earth is blue

Our planet is an ocean planet: Earth Is Blue. The National Marine Sanctuary System protects some of the most iconic underwater places throughout the United States, but we can't do it without you. No matter where you are, the ocean and Great Lakes are in your hands. We hope these images inspire you to help care for our ocean and to spread the word that Earth isn't green – it's blue.

Purplish-white octopuses tucked in a rocky nook with arms facing outward

Today is International Mountain Day – and did you know that there are mountains in the ocean? Seamounts are undersea mountains formed by volcanic activity, and they're typically biological hotspots. For example, on Davidson Seamount in NOAA's Monterey Bay National Marine Sanctuary, researchers with Nautilus Live encountered more than a thousand Muusoctopus octopuses tucked into nooks! Most of the octopuses had their arms inverted in a brooding posture. We love a good octopus garden, but we love an octopus garden on an ocean mountain even more!

A Laysan albatross

Wisdom is back in Papahānaumokuākea Marine National Monument! Wisdom is a female Laysan albatross and the oldest known banded bird in the world. At least 69 years old, Wisdom is a world-renowned symbol of hope for all species that depend upon the health of the ocean to survive. Each year, she and her mate Akeakamai return to Midway Atoll National Wildlife Refuge in the monument to mate, lay an egg, and raise their chick. To date, Wisdom has hatched more than 35 chicks over the course of her life. Welcome back, Wisdom!

A bluehead wrasse swims over an Orbicella coral

Looking for a way to help corals stay healthy? Make sure you're using a reef-safe sunscreen or use Ultraviolet Protection Factor (UPF) sunwear! Several chemicals in traditional sunscreen can damage and kill corals, and are also harmful to green algae, sea urchins, fish, mussels, and dolphins. Even if you don't live near the ocean, when you shower, the chemicals in sunscreen may wash off and enter our waterways. So by making a small change in your sun protection, you can help support healthy coral reefs!

Red arms of a brittle star reaching out from beneath a coral to catch coral gametes

Who's that reaching out from the coral reef of NOAA's Flower Garden Banks National Marine Sanctuary? A sneaky brittle star! Every August, the reef-building corals within the sanctuary put on one of the most abundant spawning displays in the entire Caribbean and Gulf of Mexico. Each coral species times its gamete (egg and sperm) release to ensure genetic mixing and that coral larvae can disperse over large distances. The gametes also provide a feast for small animals like this brittle star.

Side by side view of a reef before and after bleaching

What's wrong with this picture? These two images show a reef in NOAA National Marine Sanctuary of American Samoa just months before (left) and after (right) a bleaching event. When we burn energy sources like gasoline and coal, we release carbon dioxide into the atmosphere. This carbon dioxide acts like a heat-trapping blanket, keeping heat from the sun close to the planet and warming the atmosphere and the ocean. Corals are sensitive to temperature: if the water gets too warm, they expel the colorful algae that they need to survive. This is called bleaching, and if it lasts long enough, the corals can die. But there are things we can do: by working with your community to curb your fossil fuel consumption and reduce other coral stressors, like pollution, you can help protect vibrant coral reefs!

A pink deep-sea coral covered in brittle stars

Did you know there are corals in the deep ocean? It's true! Many species of coral thrive in the deep sea, like this Swiftia coral in NOAA's Cordell Bank National Marine Sanctuary. The corals position themselves so they can grasp small particles of food from the current, and also provide habitat for other animals like these brittle stars. What other deep-sea dwellers can you spot here?

Top: a humpback whale feeding; bottom: humpback whales swimming underwater.

Happy birthday to NOAA's Stellwagen Bank National Marine Sanctuary and Hawaiian Islands Humpback Whale National Marine Sanctuary! Though thousands of miles apart, both of these sanctuaries offer refuge to humpback whales. Each summer, humpback whales migrate from the Caribbean to Stellwagen Bank off the coast of Cape Cod, Massachusetts, where they and other whales feast on the food that flourishes in sanctuary waters. And in the Pacific, humpback whales journey to the warm waters surrounding the Hawaiian Islands each winter to mate, calve, and raise their young.

A purplish octopus sitting on top of a submersible's sampling instruments

Citizen science isn't just for people anymore! This Muusoctopus octopus hopped aboard Nautilus Live's ROV Hercules last week to get a better look. Hercules was exploring a whale fall in NOAA's Monterey Bay National Marine Sanctuarythat was being scavenged by octopuses, fish, and other animals. The octopus crawled along Hercules' sampling vessels before presumably going back to eat some more. A whale fall – the carcass of a whale that has sunk to the seafloor – can feed communities of organisms for months or years.

Octopuses and other animals on a whale skeleton on the seafloor

Scientists aboard the E/V Nautilus got a treat yesterday when they came across a whale fall in NOAA's Monterey Bay National Marine Sanctuary! When whales die at sea, they sink to the seafloor where they can feed other organisms for years. There, the whale carcass or skeleton is known as a whale fall. The Nautilus Live team found this whale fall at a depth of 10,623 feet while exploring Davidson Seamount, an underwater mountain. The whale skeleton is lying on its back and is an estimated 13 to 16 feet in length. The team is working to identify the species, but it is confirmed to be a baleen whale. Look closely and you can see Muusoctopus octopuses and other marine animals!

We're not squidding around when we say we love cephalopods! Photographer Alexander Neufeld describes his encounter with this beautiful reef squid in NOAA Florida Keys National Marine Sanctuary this way: "A reef squid in the black waters off of Key Largo during a night dive. Several squid joined us during a portion of the dive, hovering just below the surface, which allowed for the reflection of the squid's body in the final image. Once the squid had enough of us, it took off in a cloud of ink."

Meet the giant clam, also known as faisua in Samoan! These beautiful clams can be spotted in the coral reefs of NOAA National Marine Sanctuary of American Samoa. Once nestled into a location on the reef, a giant clam will remain stationary throughout its life. Like corals, giant clams have developed symbiotic partnerships with algae called zooxanthellae. In return for shelter, zooxanthellae provide giant clams with nutrients they've photosynthesized – and help give the clam's mantle its pretty colors.

Located in NOAA's Monterey Bay National Marine Sanctuary, Elkhorn Slough is one of California's great estuaries. Flushed by ocean tides in the heart of Monterey Bay, its waterways, mudflats, and marsh support a huge diversity of wildlife. Estuaries like Elkhorn Slough provide food, shelter, migration stopovers, and places to breed for many animals. However, they're also quite delicate and need our help to ensure they remain thriving ecosystems. Learn more about estuaries and how you can support them.

 A mass of nets, rope, and marine debris in shallow water, with a man working to remove them

What happens to trash after it flows down a creek or falls off a vessel at sea? Usually, it stays in the ocean for a long, long time. There, it can choke animals who mistake it for food, or entangle animals and drown them. This huge conglomeration of fishing nets and other trash was removed from French Frigate Shoals in Papahānaumokuākea Marine National Monument by NOAA Marine Debris and partners. Since 1996, they have removed 1017 tons of debris the remote expanses of the Northwestern Hawaiian Islands, which is about the same weight as nine blue whales! You can help keep debris out of the sea by participating in a cleanup this weekend for the International Coastal Cleanup, or any other day of the year.

A humpback whale lunge feeding, with seabirds flying around it

This humpback whale is lunging out of the ocean to wish NOAA's Monterey Bay National Marine Sanctuary a very happy birthday! 🐋🎂 And also, of course, to get a mouthful of fish, because what's a celebration without snacks? This iconic sanctuary protects 36 species of marine mammals, more than 180 species of seabirds and shorebirds, 525 species of fish, and a multitude of invertebrates and algae. How many can you name?

Eyes of a hawk, and ears of a...fish?
Stocky hawkfish are known as po‘opa‘a in Hawaiian. In the coral reefs of Papahānaumokuākea Marine National Monument, they linger atop corals and survey their surroundings for prey, much like their terrestrial namesake. As an added level of protection, a stocky hawkfish’s pectoral fins are resistant to the stinging cells of fire corals, which normally harm other organisms upon contact. Well played, hawkfish. Well played.

Two divers installing a buoy near a seagrass bed

Oh buoy! This drill team is hard at work installing new mooring buoys in NOAA Florida Keys National Marine Sanctuary. Buoys allow boaters to enjoy their time out on the water without damaging the coral reef and seagrass bed ecosystems that lie beneath them. Buoys serve as as an alternative to anchoring, which is prohibited in waters less than 40 feet deep, and can also be used as markers relaying specific information about the area.

Whale, whale, whale, what do we have here?
Whale watchers in NOAA's Monterey Bay National Marine Sanctuary got a surprise visit from a gray newborn orca calf traveling with 10 members of the transient orca pod known as the CA216 family. While most orcas are black and white, little is known about the uncommon gray pigment of this youngster. The science is clear on one thing – this newborn is 100% adorable!

Orange and white sea anemones clustered together.

In addition to being markers of our maritime past, shipwrecks are home to a vast number of marine species – like these frilled anemones on the wreck of the Portland in NOAA's Stellwagen Bank National Marine Sanctuary. Next week, researchers from Woods Hole Oceanographic Institution (WHOI) and Marine Imaging Technologies will be visiting Portland and other shipwrecks to assess the state of the wrecks. They'll be livestreaming their expedition, and you can tune in while they journey deep beneath the ocean's surface! Leran more abouth this expedition.

A diver swimming over a large shipwreck.

Mondays are for maritime history, and NOAA Thunder Bay National Marine Sanctuary has got lots of it! D.M. Wilson, pictured here, is one of the many wrecks sitting at the bottom of Thunder Bay National Marine Sanctuary in Lake Huron. In 1894, the wooden ship was headed for Milwaukee with its usual shipment of coal when a leak stopped it in its tracks. Despite attempts to tow it to safety, the ship sank near Thunder Bay Island. Today, divers can see most of the Wilson’s hull, which remains largely intact!

Reef fishes cleaning two sea turtles.

Happy National Wildlife Day! Not only are we celebrating our sanctuary wildlife, but also the partnerships that exist between many of them. In Hawaiian Islands Humpback Whale National Marine Sanctuary, sea turtles like these two get routine clean-ups from grazing reef fish at “cleaning stations” found along the reefs. The fish keep the sea turtles free of algae and other organisms that live on them, while the reef fish get a snack! A win-win situation if you ask us.

When is a whale not a whale? When it's a whale shark! While whales are mammals, whale sharks are actually fish, named for their vast size. Like some whales, they are also filter feeders, chowing down on plankton. During the summer months, whale sharks travel to NOAA's Flower Garden Banks National Marine Sanctuary in the Gulf of Mexico to find this favorite food.

A sea otter napping on the water.

Nothing hits the spot like a midday nap, especially for sea otters! Due to their high metabolism, sea otters – like this one in NOAA's Monterey Bay National Marine Sanctuary – have to eat and rest a lot as part of their daily routine. As otterly adorable as they are, it’s important to keep a safe viewing distance when coming across a sea otter in the wild so you don't interrupt the time they need to take care of themselves. Keep sea otters safe and undisturbed by respecting their space, and their naps!

Witnessing the spectacular wildlife of our national marine sanctuaries – like this humpback whale in Hawaiian Islands Humpback Whale National Marine Sanctuary – is always whaley exciting! It’s important to keep a safe viewing distance to make sure the wildlife aren’t disturbed by our admiration. In Hawai’i, whales cannot be approached closer than 100 yards, which protects humpback whales and whale watchers alike.

Animal or plant? Both the feathery object and the coils in this photo may look like plants (or something otherworldly) but they're actually animals! Researchers from the Global Foundation for Ocean Exploration and NOAA's Flower Garden Banks National Marine Sanctuary witnessed this reef at Alderdice Bank in the Gulf of Mexico. The feathery creature is a feather black coral, while the coils are known as sea whip corals. Both feed on plankton that is swept by in the current!

This photo is from an ongoing expedition that is livestreaming dives from areas in and around Flower Garden Banks National Marine Sanctuary. Tune in and learn more.

A brightly colored sea anemone

Keep your friends close, and your anemones further away! Sea anemones – like this one found in NOAA Florida Keys National Marine Sanctuary – are close relatives of coral and jellyfish. While their brightly colored tentacles are a beautiful sight, they are actually venomous and are used for capturing prey. Most species are benign to humans, but keeping your hands to yourself protects both you and the animal. Don't make an enemy of a sea anemone!

Just kidding! This isn't a plant – it's a white-lined nudibranch. Nudibranchs, like this one found in NOAA's Monterey Bay National Marine Sanctuary, are sea slugs that often come in striking colors and forms. While they may look like they're making a fashion statement, nudibranchs often depend on their brilliant colors as defense from predators.

We’re a big fan of deep-sea fans! This fan coral and its fish friends were found at a depth of about 100 meters in the Santa Cruz Canyon, part of NOAA Channel Islands National Marine Sanctuary. Unlike their shallow-water relatives, deep sea corals don’t need sunlight to thrive; instead, they obtain energy and nutrients by trapping tiny organisms that pass through the water. Pretty fan-tastic if you ask us!

A reddish-orange octopus nestled in among lobe coral.

A day octopus – or he’e mauli in Hawaiian – sits pretty at French Frigate Shoals in Papahānaumokuākea Marine National Monument. Many cephalopods have special cells in their skin tissue called chromatophores that enable them to change color very rapidly. A part of their neuromuscular system, these cells receive signals from the environment that an octopus can use to inform color change. Octopodes of this particular species can change color almost instantly as they move over their environment, making them nearly invisible to predators!

A lionfish swimming near a coral reef.

For World Lion Day, we're bringing you the lions of the sea: Indo Pacific lionfish. As their name suggests, these fish are native to the Indo Pacific region, and are part of the food web in coral reefs in that area. In recent decades, though, these fish have been found in coral reefs throughout the southeast Atlantic, Gulf of Mexico, and Caribbean – including in NOAA Gray's Reef National Marine Sanctuary, NOAA's Flower Garden Banks National Marine Sanctuary, NOAA Florida Keys National Marine Sanctuary, and NOAA Monitor National Marine Sanctuary. Experts speculate that people have been dumping unwanted lionfish into the ocean for the last 25 years or more.

In their newfound habitats, lionfish don't have natural predators – plus, they have voracious appetites and reproduce quickly. This may spell trouble for biodiversity in coral reefs. a group of 1,000 lionfish can consume 5 million prey fish in a single year! NOAA and our partners are working to understand and control this invasive species with new traps, lionfish derbies, and more. You can help by asking restaurants near you to serve lionfish, and learn more here.

Sometimes it can be hard for maritime archaeologists to document shipwrecks because of all the fish! Here, NOAA Monitor National Marine Sanctuary archaeologist Will Sassorossi and NOAA Ship Nancy Foster's navigation officer ENS Sara Thompson explore the shipwreck of the USS Schurz, which sank during World War I off the coast of North Carolina. Shipwrecks like the USS Schurz have a second life beneath the waves as artificial reefs. Invertebrates like anemones and corals may attach to the wreck surface, while fish like the many seen here shelter and feed around the wreck.

How important is water quality to our marine and freshwater ecosystems? Important enough that we dedicate a month to celebrate it! August is National Water Quality Month. Our national marine sanctuaries depend on clean water to ensure that biological diversity, coastal scenery, and recreational and commercial opportunities thrive. During “Snapshot Day” in NOAA's Monterey Bay National Marine Sanctuary, hundreds of citizen science volunteers aid in water quality efforts, assessing rivers, streams, and other coastal California watersheds.

A hammerhead shark swimming.

Ever wonder what it might be like to have a sixth sense? Sharks have that covered! Specialized organs called ampullae of Lorenzini help these stealthy hunters detect small electrical fields released by other animals. That way, sharks can sense their prey even if it's buried in the sand or in murky water. Hammerhead sharks – like this one in NOAA Gray's Reef National Marine Sanctuary – have an especially large number of these ampullae on their broad head.

This Laysan albatross, or mōlī, in Papahānaumokuākea Marine National Monument is in for a surprise. Tiger sharks like this one are voracious predators, much like their terrestrial namesake, and are known to take a bite out of just about anything that catches their attention. Though they can be frightening, sharks like the tiger shark are incredibly important animals in ocean environments. Sharks help remove dead or decaying debris from the ocean, and thereby help keep our ocean clean, while also helping to keep ecosystems in balance.

Trash and animals don't mix well! Do you know what to do if you spot a marine mammal in distress?

First off, don't try to approach or disentangle the animal yourself. Wild animals – especially scared ones – can be volatile, and may injure you or themselves. Instead, contact your local stranding network so that trained professionals can safely help the animal in distress. If you're in Monterey Bay National Marine Sanctuary, where this fur seal was spotted, contact The Marine Mammal Center hotline (San Francisco Bay Area: 415-289-7325; Monterey or Santa Cruz Counties: 831-633-6298; San Luis Obispo County: 805-771-8300).

Ever wondered what paradise looks like? Well look no further! The beaches and coasts of NOAA National Marine Sanctuary of American Samoa are truly a sight to sea. However, marine debris not only threatens the diverse wildlife protected by the sanctuary, but it can also be an eyesore for those who admire these beautiful and culturally-significant landscapes. When celebrating Independence Day, keep in mind that trash travels! You can help preserve our national marine sanctuaries by cleaning up after yourself and encouraging those around you to do the same.

A brightly colored reef with fish.

Bereef it or not, every year around 8 million metric tons of plastic make their way into our ocean! Trash that is left behind on shores and beaches are often swept into the ocean by high tides and wind, and can travel thousands of miles once it enters the water. Even deep ecosystems far from shore, like this one in NOAA's Cordell Bank National Marine Sanctuary, can be impacted plastic pollution. If you're visiting a beach this week for the Fourth of July, help keep our ocean clean and reefs healthy by joining a beach clean up, or take the lead and organize one!

A fairy is among us! A fairy tern chick, that is. Known as manu-o-kū in Hawaiian, fairy terns are native to the Northwestern Hawaiian Islands, including Papahānaumokuākea Marine National Monument. Unlike most seabirds, fairy terns lay their eggs directly onto a surface like a tree branch or cliff ledge, rather than building a traditional nest! When the chicks hatch, they use their sturdy claws to grip onto the surface, which helps them weather even the strongest winds and storms.

A shipwreck underwater, covered in marine

Sink into some maritime history with NOAA Monitor National Marine Sanctuary! The USS Monitor, pictured here, was the first ironclad warship in the Union army. In 1862 in the throes of the Civil War, Monitor led the Union into battle against the Confederate ironclad CSS Virginia at the Battle of Hampton Roads. While the battle ultimately resulted in a draw, it marked the end of an era for wooden warships! Later that year, the USS Monitor met its fateful end off the coast of North Carolina during a treacherous storm, along with 16 brave members of its crew. Over a century later when the shipwreck was discovered, Monitor National Marine Sanctuary was designated as the first national marine sanctuary in the United States to protect our maritime heritage.

Humpback whales aren’t the only ones that enjoy the waters of Hawaiian Islands Humpback Whale National Marine Sanctuary! The sanctuary is also the perfect spot for responsible recreation. This surfer is riding the famous “Pipeline,” or “Pipe,” wave break on O’ahu’s North Shore, one of the most powerful (and dangerous) surf spots in the world. Have you surfed in Hawaiian Islands Humpback Whale National Marine Sanctuary or other sanctuaries?

A bird sticking up above a tree.

"Did someone say it's snack time?" This black-crowned night heron was spotted resting in a tree on the coast of NOAA's Greater Farallones National Marine Sanctuary, possibly wondering if it's time for to go eat yet. These herons typically feed between evening and early morning, which helps them avoid competition with other heron species.

A gray seal with its head above the water.

When gray seals and other seals hang out in the water upright like this one, they're said to be "bottling." Gray seals are often spotted within NOAA's Stellwagen Bank National Marine Sanctuary, where – between rests – they feed on fish, crustaceans, squid, and sometimes even small seabirds. While gray seals may appear approachable in the wild, human interference is a major threat to these marine mammals. Fishing entanglements, watercraft strikes, and interactions with humans put them at risk. Help protect gray seals by keeping a safe distance and not approaching them too close on land or on water.

In September of 2017, Hurricane Irma tore through NOAA Florida Keys National Marine Sanctuary, carrying large amounts of marine debris into the ocean. In response, the sanctuary and the National Marine Sanctuary Foundation launched Goal: Clean Seas Florida Keys to help professional dive shops lead underwater cleanup efforts in the sanctuary. In its first year, the initiative removed more than 18,000 pounds of marine debris from sanctuary waters!

Is it a plant? A coral? An extraterrestrial life form?

If you said none of the above, you’re correct! This crinoid in NOAA National Marine Sanctuary of American Samoa is a marine animal related to sea stars and sea urchins. Many crinoids can attach themselves to a hard surface, and use their feathery pinnules to catch plankton from the water.

An angler returning a fish to the water.

Wisdom might get all the attention for being the world’s oldest known banded bird that has raised around 35 chicks in her lifetime (and counting!), but have you met her equally dedicated mate, Akeakamai?

Each year since 2006, Akeakamai, a Laysan albatross, has returned to Midway Atoll in Papahānaumokuākea Marine National Monument with his mate Wisdom to raise a chick. Over the course of several months, both parents take turns incubating the egg. When they’re not on parenting duty, they forage for food. Once the egg hatches, both parents spend another 5 to 6 months raising the chick before it leaves the island. Happy Father's Day to Akeakamai and all the dedicated dads out there!

Happy birthday to Papahānaumokuākea Marine National Monument! The monument is of great importance to Native Hawaiians, with significant cultural sites found on the islands of Nihoa and Mokumanamana. It also protects an incredible diversity of marine life, including marine mammals, sea turtles, and 14 million seabirds. Thanks to the protection of the monument, the inhabitants of Papahānaumokuākea – like this Hawaiian monk seal and green sea turtle – can rest a little easier each night (and day)!

We're totally at loggerheads over which sea turtle species is our favorite! This loggerhead sea turtle was spotted in NOAA's Flower Garden Banks National Marine Sanctuary. Loggerheads' powerful jaws enable them to feed on hard-shelled prey, such as whelks and conch. Adults can reach up to 250 pounds! Photo: G.P. Schmahl/NOAA
A leatherback sea turtle poking its head above the water with a jellyfish in its mouth.
Did you know that leatherback sea turtles – like this one in NOAA's Monterey Bay National Marine Sanctuary – are the largest living turtle species? Leatherbacks swim thousands of miles across the Pacific Ocean to reach Monterey Bay to feast on jellyfish. This one is slurping up a brown sea nettle. Sometimes, though, what looks like a tasty jelly snack turns out to be a plastic bag. Since leatherbacks aren’t able to regurgitate plastics if they mistakenly eat them, it’s critical that we keep our ocean plastic-free and leatherback-friendly! Photo: Douglas Croft Images

Each year for World Oceans Day, we celebrate the lifegiving force that is our ocean. The ocean provides the oxygen we breathe, sustains an amazing array of animals and plants, and more. This year, we're especially celebrating the critical role that gender equality plays in ocean conservation! From the scientists conducting important marine research – like NOAA's Flower Garden Banks National Marine Sanctuary ecologist Dr. Michelle Johnston, pictured here – to the educators teaching the next generation about the ocean, our ocean (and all of us!) is indebted to the women and people of all genders who protect it.

"The more clearly we can focus our attention on the wonders and realities of the universe about us, the less taste we shall have for destruction." - Rachel Carson

Happy birthday to "the mother of the age of ecology," Rachel Carson! Rachel Carson believed we are all responsible for caring for our natural world, and her dedication to environmental preservation has inspired generations. We can all do our part to carry on Carson's legacy and become better stewards of our blue planet, whether it's through removing marine debris or reducing our carbon footprints. What will you do? Let us know in the comments!

A diver hovering over a shipwreck.
"Each dive is a story in itself. Every visit to a shipwreck, reef, and underwater community tells a new story of loss and love. The environment in which a shipwreck rests, exists, and thrives also adds to the story, creating new chapters that only the diver will witness firsthand. Hopefully the diver can bring this story to the surface to be told to the public and inspire a new generation of adventure seekers to don the gear and bring a new story for generations to come. In most cases the treasures within these sanctuaries can, should, and will hopefully outlive us all." – Jeremy Bannister, NOAA Thunder Bay National Marine Sanctuary volunteer and diver

A brain coral releasing small, circular gametes into the water column
Do you ever feel a little spawntaneous? Corals sure do! Corals can reproduce in a variety of ways, but mass spawning events like this one in NOAA's Flower Garden Banks National Marine Sanctuary are one of the most enchanting to witness, and most perplexing for scientists and researchers. Cues from the lunar cycle or water temperature stimulate entire coral reef colonies to release their tiny eggs and sperm, called gametes, at the same time into the ocean. Once these gametes are fertilized, they may form a coral larvae, or planula, which will swim freely until it settles down to grow into the adult coral that it was always meant to become!

A brown albatross with a small green band on its leg taking off from the ocean surface.

Aaaand lift-off! Albatrosses like this black-footed albatross are long-distance travelers, migrating between their feeding and nesting grounds. This particular albatross was spotted in NOAA's Monterey Bay National Marine Sanctuary by Robert Schwemmer, our West Coast Region maritime heritage coordinator, and is special because of that little bit of green you see on its leg. That's a bird band, a small tag used to identify individual birds. Thanks to Schwemmer's zoom lens, we were able to read the number on this one and match it in the U.S. Geological Survey (USGS) database.

This particular albatross was originally banded May 30, 2002 – nearly 17 years ago – when it was too young to fly. It was banded in French Frigate Shoals in what is now part of Papahānaumokuākea Marine National Monument, more than 2,700 miles away from where it was spotted in Monterey Bay! Its band can help researchers track its journey and better understand the life cycle and ecological needs of black-footed albatrosses.

Today is Endangered Species Day, so we’re honoring the largest animal to have ever lived on our planet: the blue whale! At up to 110 feet long, blue whales are truly giants of the seas, and can be seen in national marine sanctuaries like NOAA Channel Islands National Marine Sanctuary. Still, blue whales are threatened by human activity, including being struck by ships, habitat degradation, and entanglement with fishing gear. Blue whales are protected under the Endangered Species Act and the Marine Mammal Protection Act, and you can help further them by keeping a safe distance if you’re lucky enough to spot one in the wild!

North Atlantic right whales are one of the most endangered marine mammals in the world, and the sanctuary works closely with NOAA Fisheries and other partners to reduce human impacts, like collisions with vessels and entanglement in fishing gear. You can help protect right whales, too, by supporting your regional stranding network and helping raise awareness about protecting whales! (Photo: Peter Flood)

A basking shark swimming at the ocean surface.
What's a basking shark? Oh, y'know, just ONE OF THE COOLEST ocean creatures out there, and, no big deal, the second-biggest shark in the world. They can grow to about the length of a school bus, and use their gaping mouths to feed on tiny crustaceans the size of a grain of rice. They can be found in many of your national marine sanctuaries – this one was photographed in NOAA's Stellwagen Bank National Marine Sanctuary – but in the eastern Pacific, they were sighted less frequently beginning in the latter half of the 20th century.Recently, though, they've been spotted more often in and around NOAA Channel Islands National Marine Sanctuary, and two sharks were tagged by sanctuary researchers!

 A diver above a shipwreck.
The Outer Banks contain some of the most dramatic barrier islands and most dangerous shoals and currents on Earth. The area is often referred to as the Graveyard of the Atlantic because these waters have entombed thousands of vessels and countless mariners who lost a desperate struggle against the forces of war, piracy, and nature. Recently, NOAA Monitor National Marine Sanctuary archaeologists and their partners have been working to document these wrecks; several could be included in an expanded sanctuary. Here, a Monitor diver swims over the wreck of U-352, a German U-boat sunk by the USCGC Icarus in 1942.

Thirty-three years ago today, a tiny national marine sanctuary was designated to protect Fagatele Bay in American Samoa. The bay harbors incredible biodiversity – in just a quarter of a square mile, you can find at least 271 species of fishes, 186 species of coral, and at least 1,400 species of algae and invertebrates. In 2012, the sanctuary expanded to become one of the largest: NOAA National Marine Sanctuary of American Samoa. Happy birthday to this ocean treasure!

A diver exploring the wreck of Grecian
Most people think of our Great Lakes as just another muddy old lake, but that is very much not the case. I have a special love for the beautiful blue of Lake Huron and diving on the shipwrecks in Thunder Bay National Marine Sanctuary. I’ll never forget a particularly magical day diving on Grecian. It was a beautiful blue-skies, no-wind day and the visibility seemed endless. Nearly 100 feet underwater I could see the surface and the golden sun rays shimmering down to me on that exciting shipwreck.

NOAA National Marine Sanctuary of American Samoa is a hotspot for marine biodiversity! The sanctuary was originally established just to protect the reefs of Fagatele Bay, seen here. It has since expanded to become the largest of the 13 sanctuaries in the National Marine Sanctuary System. The sanctuary protects shallow and deep water coral reefs, rare marine archaeological resources, and a plethora of fish, marine mammals, and other ocean dwellers. NOAA co-manages the sanctuary with the government of American Samoa and works closely with local communities to preserve the ecological wonders and cultural traditions that are supported by the sanctuary.

It's Citizen Science Day! Thousands of citizen scientists dedicate their time across the National Marine Sanctuary System each year. By collaborating with sanctuary researchers, they help us better understand the condition of our sanctuaries and the organisms that live there. In NOAA's Stellwagen Bank National Marine Sanctuary, the citizen scientists of Stellwagen Sanctuary Seabird Stewards conduct year-round, systematic seabird surveys. Their efforts have helped reveal previously unknown details about these avian world-travelers and how they can serve as barometers of change in the marine environment. (Photo: Peter Flood)
Two volunteers picking up trash from a beach.
Have you ever come across trash strewn on your favorite beach or in your local park and wondered, “What’s that doing here?!” Trash travels, and plastic debris, aluminum cans, fishing gear, and more can end up in the ocean. But we’re here to tell you that you can help prevent it! Alongside the NOAA Marine Debris Program, our national marine sanctuaries provide opportunities for community members to volunteer their time in clean-up efforts, like these two volunteers in NOAA Olympic Coast National Marine Sanctuary. To learn more about how you can get involved, visit https://marinedebris.noaa.gov/discover-issue/solutions. (Photo: Karlyn Langjahr/NOAA)

We all live in a yellow submarine! Well, not really, but it’s National Submarine Day and we couldn't help ourselves! This brightly colored submersible, called Delta, has performed more than 7,000 deep-water dives, many of which were in and around NOAA Channel Islands National Marine Sanctuary. It’s also nicknamed “the Jeep of the Seas”! (Photo: Robert Schwemmer/NOAA)
An orca spyhopping.]
NOAA's Monterey Bay National Marine Sanctuary hosted some surprise Spring Break visitors last week! The L pod of southern resident orcas traveled far from their usual feeding grounds near NOAA Olympic Coast National Marine Sanctuary, likely in search of Chinook salmon, their primary food source. The L pod is led by an older female believed to be 90 years old, and is composed mostly of related females and their offspring. Even a three-month-old calf was spotted with the group! They are well studied in the Pacific Northwest, and are known to be highly social with unique vocalizations. (Photo © J. Flowers/Monterey Bay Marine Life Studies www.marinelifestudies.org

We’re here to tell you a tail about the blue whale. Baleen it or not, blue whales are the largest known animal to have ever existed on Earth! Their tongues alone can weigh as much as an elephant, and their hearts are as large as a small car. In the summer and fall feeding seasons, blue whales travel to the California coast, including NOAA's Monterey Bay National Marine Sanctuary, to gulp down shrimp-like krill (about four tons a day, to be exact!).

Piracy on the open ocean! Parasitic jaegers get their name from their habit of pursuing other birds and forcing them to drop their catch so the jaeger can take it. Also known as Arctic skuas, these birds breed in the Arctic then migrate south along coastlines. Here, a parasitic jaeger is pursuing a laughing gull near NOAA's Stellwagen Bank National Marine Sanctuary. (Photo: Peter Flood)

Hannah (left) and a second person snorkel down to a shipwreck.
"At the age of 14, I became open water dive certified. I had spent summers before snorkeling the shipwrecks of NOAA Thunder Bay National Marine Sanctuary and couldn't wait to be fully submerged in scuba gear on one of the historical wrecks. My first dive in the Great Lakes was on a shipwreck in Thunder Bay National Marine Sanctuary called Joseph S. Fay. My dad was my dive buddy and will never forget the bliss I had while exploring a shipwreck underwater without having to stay at the surface. Six years later, I returned to Joseph S. Fay at sunrise with a group of women divers completing a feat of diving all five of the Great Lakes in 24 hours. This time, my dad and scuba instructor cheered on the shore as the sun rose over Lake Huron. The sense of place, community, and desire for exploration that the National Marine Sanctuary System has instilled in me motivates me everyday.

We wreckon that documenting submerged artifacts and shipwrecks is no easy feat! That’s why we've been collaborating with Diving With A Purpose, or DWP, for over a decade to collect underwater artifacts, create site maps, and educate the public about maritime archaeology and the history of our national marine sanctuaries. Founded with support from the National Association of Black Scuba Divers, DWP helps educate, train, and provide field experiences to youth and adults interested in maritime archaeology and marine conservation, with a special focus on documenting African-American submerged artifacts, slave trade shipwrecks, and coral reef restoration. You can find NOAA and DWP divers working in NOAA Florida Keys National Marine Sanctuary and NOAA Thunder Bay National Marine Sanctuary! Check out some of their recent work.

When you can’t find protection in the open ocean, you bring the protection to you! That’s exactly what these small fish in NOAA Channel Islands National Marine Sanctuary are doing. In need of a shelter from predators, the fish gather tightly together to form a round “bait ball.” By hiding close to one another, most of them can be protected. As the old adage goes, teamwork makes the dream work...except for those unlucky fish on the edges. (Photo: Robert Schwemmer/NOAA)

“Hey, I have a whaley funny joke for ya. What do you call a pod of musical orcas?" ... “An orca-stra! *buh dum tss!*” When they aren’t splashing around dad jokes, orcas can be sighted sporadically along North America’s West Coast, including in NOAA's Monterey Bay National Marine Sanctuary. The best time to spot an orca in this sanctuary is from April until June, when they feed on migrating gray whales. (Photo: Douglas Croft Images)
A close-up of an orange branching coral.
Staghorn coral were once a dominant species on Caribbean reefs, including those of NOAA Florida Keys National Marine Sanctuary. Beginning in the 1980’s, pressure from disease, climate change, pollution, and overfishing began to take a toll on the reef-building corals, and populations declined by around 97 percent. However all is not doom and gloom! Researchers at Florida Keys National Marine Sanctuary and NOAA Fisheries are working hard to protect and manage the sanctuary’s corals through staghorn coral nurseries, protective activities, zoning and channel markings, and other restoration efforts.

A silhouette of kayakers paddling through a rock arch.
"I recently took a group of 27 elementary school students kayaking in the Santa Barbara Harbor. For many of these Ocean Guardian Ambassadors and their parents, it was their first hands-on experience with the ocean and they had never been on a kayak before. It was amazing to see the transformation of one young student on my kayak, who started out terrified and severely uncomfortable to eventually becoming an future ocean lover. An hour and a half into the experience, she was running her hand through the water, taking a turn paddling and asking when we would get to kayak again." – Claire Fackler, ONMS national volunteer coordinator What inspires you about the ocean?

A pelican diving toward the water.
How would you score this pelican's dive? Brown pelicans – like this one in NOAA's Monterey Bay National Marine Sanctuary – plunge into the water to catch fish with their heads pointed straight down and their wings folded back. Their sharp eyesight helps them spot a meal from heights of 20 to 60 feet! It’s no wonder they are called pelicans and not pelican’ts. (Photo: Douglas Croft Images)
Sunrise over Lake Huron.
Today is World Water Day! The Great Lakes contain about 21 percent of the world's supply of surface fresh water, and provide water for drinking, agriculture, transportation, power, recreation and a host of other uses. In NOAA Thunder Bay National Marine Sanctuary in Lake Huron, you'll also find history: the sanctuary protects some 200 shipwrecks that hold stories of our nation's maritime past. What body of water are you grateful for today? (Photo: Nick Zachar/NOAA)

Day to day, the feather duster worm lives in a tube it builds itself from sand. When it emerges from the tube, the worm’s gills spread open like a housekeeping feather duster, helping it sweep the sea for a dinner of microscopic plankton. (Photo: Greg McFall/NOAA)
A humpback whale underwater trailing fishing gear
This is some whale-ly exciting news! On March 6, Hawaiian Islands Humpback Whale National Marine Sanctuary coordinated an effort to free a young humpback whale off Maui. The whale was entangled in heavy gauge line through its mouth that trailed several hundred feet behind it. The disentanglement team managed to remove all but a small amount of the line – 400 feet of line was removed in all! The recovered gear has been identified as pot gear set off Dutch Harbor, Alaska, which is more than 2,500 miles from the sanctuary. We're so glad this whale now has a better chance of surviving and thriving! Learn more about the disentanglement effort. If you see a whale in distress, please DO NOT attempt to aid it yourself – that can be extremely dangerous for both you and the whale. Instead, maintain 100 yards distance and call the NOAA 24-hour Hotline at 1-888 256-9840. If you're unable to call, please radio the U.S. Coast Guard on VHF CH. 16 and they will relay the report.

Many species of marine algae competing for space.
Algae the first to say there's a lot of seaweed growing here! Low tides during the summer revealed a diverse array of algae species competing for space on tidal rocks in the Makah Reservation. Researchers from NOAA Olympic Coast National Marine Sanctuary monitor seawater temperatures and intertidal organisms like algae, sea stars, and mussels here each year. It's part of a collaborative effort with the Makah Tribe and the Multi-Agency Rocky Intertidal Network (MARINe), which monitors dozens of intertidal sites spanning the U.S. West Coast.

Happy St. Patrick's Day from this green moray eel in NOAA Florida Keys National Marine Sanctuary! Green moray eels are actually brownish, but they don green in celebration of holiday – or, rather, to protect themselves from parasites and disease. That is, these eels secrete a yellowish mucus that covers their skin, giving them a greenish tinge. (Photo: Greg McFall/NOAA)

We don't yet know what causes the color difference! (Photo: Steve Miller)
A diver on a shipwreck in NOAA Thunder Bay National Marine Sanctuary
The first time I dove a wreck in the Great Lakes, my breath was taken away, more from the vision than the cold. The wreck that had sunk over 150 years ago lay clearly below me. It was a time capsule. The cold, fresh waters of Lake Huron had perfectly preserved the ship. Rigging was still threaded through wooden dead-eyes. The deck forward still held the anchors in place ready to be deployed. Great Lakes diving is my favorite. The preservation and history are unprecedented." – Michael Moulton, public school teacher and scuba instructor What inspires you about the ocean and Great Lakes?

A close-up of a pufferfish resting among seagrass
This month, we celebrate one of our favorite marine photosynthesizers: seagrasses! Seagrasses are flowering plants that grow on the ocean floor, particularly in shallow waters. Seagrass beds – such as those in NOAA Florida Keys National Marine Sanctuary – provide shelter and food for many organisms, like this pufferfish! These lush marine meadows also help filter nutrients from stormwater runoff and trap sediments that would otherwise float to sensitive nearby coral reefs. Boat propellers can dislodge seagrasses from the ocean floor, damaging this critical habitat. You can help seagrasses and pufferfish alike by avoiding boating in shallow waters that are home to seagrasses. (Photo: NOAA)
Research scientists riding on a small boat.
Happy International Women’s Day! Our national marine sanctuaries and marine national monuments are indebted to the hard work and research conducted by women scientists and resource managers. Dr. Nancy Foster Scholar Andrea Kealoha is one such scientist. For her Ph.D. research, Andrea studies water chemistry and coral reefs, aiming to understand how coral reefs like those of NOAA's Flower Garden Banks National Marine Sanctuary will respond to a changing ocean. In 2016, Andrea and a rapid-response team assessed water and reef invertebrate health at East Flower Garden Bank after a localized mortality event hit. Learn more about her research and what she found. (Photo courtesy of Andrea Kealoha)
A pink coral with cloud-like material floating above it.
Like many of us, corals like to be spawn-taneous! The "cloud" above this cauliflower coral in Papahānaumokuākea Marine National Monument is actually reproductive material, or gametes, being ejected out into the water. Spawning like this helps ensure genetic diversity, because coral larvae may travel long distances and settle on distant reefs. In many coral species, these spawning events only occur once a year and may last for only 10 minutes, making them pretty special for researchers to witness. Studying coral spawning can help scientists assess the impact of environmental disturbances on coral reproductive health. (Photo: Lindsey Kramer/USFWS)

Whale, what do we have here! This gray whale and her calf are embarking on a great migration north along the California coast en route to their summer feeding grounds in the Arctic. On their way, they may travel through several national marine sanctuaries, including NOAA's Monterey Bay National Marine Sanctuary and NOAA Channel Islands National Marine Sanctuary. Gray whales have the longest recorded annual migration of any mammal, traveling about 10,000 miles round-trip between their breeding and feeding grounds. Next stop, Arctic buffet! (Photo: NOAA)

A dolphin backflipping above water.
We’re backflipping into Dolphin Awareness Month with this Pacific white-sided dolphin in NOAA's Monterey Bay National Marine Sanctuary! Pacific white-sided dolphins are highly social animals that can be seen traveling in schools of up to a thousand individuals. They are also very playful, and can be spotted “bow riding,” or swimming near the front part of a ship, jumping, somersaulting, and spinning in the air! Pacific white-sided dolphins are protected by the Marine Mammal Protection Act, but they still face threats from fishing gear entanglement and underwater noise pollution. You can help by keeping a distance from the dolphins, and reporting dolphins that are in distress. Learn more about how you can help these charismatic whales. (Photo: Douglas Croft Images)
Sea otter on its back eating a crab
Happy World Wildlife Day! Humans all over the world depend on healthy ocean wildlife. For example, sea otters – like this otter chowing down on a crab – help keep kelp forest ecosystems in NOAA's Monterey Bay National Marine Sanctuary and elsewhere healthy. In turn, healthy kelp forests serve as a nursery for fish; they also absorb wave action, reducing coastal erosion. What's your favorite kind of ocean wildlife? (Photo: Jenni Peters)
A shipwreck propeller covered in mussels.
Shipwrecks and submerged archaeological resources in NOAA Thunder Bay National Marine Sanctuary have become a popular home for invasive quagga and zebra mussels. Mussel colonization can deteriorate these archaeological time capsules, making it more difficult for archaeologists, historians, and resource managers to document the wrecks. Zebra and quagga mussels also pose a threat to their local ecosystem; as consumptive filter feeders, each mussel can filter a liter of water per day! This depletes the food supply for many native fish and invertebrate species. And that’s a wrap for Invasive Species Week! Learn more about invasive species in our national marine sanctuaries. (Photo: David J. Ruck/NOAA)
Close-up on Asian kelp
Asian kelp, or "wakame," is an invasive species of kelp native to Japan that has colonized harbors along the California coastline, including in NOAA's Greater Farallones National Marine Sanctuary and NOAA's Monterey Bay National Marine Sanctuary. Wakame colonizes ecosystems rapidly and densely. That can alter the habitat of native species by reducing the amount of light cover and and restricting water movement. Thanks to a little kelp from national marine sanctuary scientists and volunteers, wakame removal and research efforts are well underway! Studying wakame will help improve management practices of the invasive species while improving understanding of how it impacts local ecosystems. (Photo: Steve Lonhart/NOAA)

Invasive lionfish can have seriously negative impacts on ecosystems in NOAA's Flower Garden Banks National Marine Sanctuary and NOAA Florida Keys National Marine Sanctuary. Sanctuary researchers are working to better understand and remove this species, and you can help, too! For one thing, recreational divers and snorkelers can participate in lionfish derbies. Lionfish are pretty tasty, too, so by encouraging local grocery stores and restaurants to carry them, you help control their populations.

Two opalescent nudibranchs crawling over a red invasive bryozoan.
These opalescent nudibranchs seem unfazed that the rust-colored bryozoan they are crawling over is an invasive species that’s taken up residence in NOAA's Monterey Bay National Marine Sanctuary. Watersipora subtorquata is a filter-feeding invertebrate that grows on hard surfaces like rocks, pier pilings, and ship hulls. It's a problem along the West Coast, where it can harm native invertebrate species by smothering them or outcompeting them for space. Monterey Bay National Marine Sanctuary researchers continue to study Watersipora to understand how it is impacting the health of the sanctuary. Learn more about invasive species!.

 Bright orange coral.
This orange cup coral may be beautiful, but it's an invasive species in NOAA's Flower Garden Banks National Marine Sanctuary and NOAA Florida Keys National Marine Sanctuary. This Indo-Pacific hard coral has established itself throughout the tropical western Atlantic, Caribbean, and Gulf of Mexico. Scientists believe it may have made the journey attached to ship hulls or within ship ballast water. Orange cup coral displaces native corals and sponges, taking up space in which native species would normally establish themselves. Also, because these corals reproduce at a young age and larvae may float on the current for up to 14 days before settling, they are able to spread far and wide. In Flower Garden Banks National Marine Sanctuary, sanctuary staff have worked to remove orange cup coral from the reef to keep it from getting too established. (Photo: NOAA)
A lionfish swimming over a coral reef.
Invasive Species Week is upon us, and what better way to kick off the week than with the infamous *drumroll please* lionfish! In recent years, Indo-Pacific lionfish have been found in coral reefs throughout the southeast Atlantic, Gulf of Mexico, and Caribbean – including in sanctuaries like NOAA Florida Keys National Marine Sanctuary Because of their voracious appetites, rapid reproduction rate, and lack of natural predators, these invasive lionfish post a serious threat to coral reefs, with potential long-term consequences for native fish communities, habitats, and entire ecosystems. Learn more about this invasive species. (Photo: Greg McFall/NOAA)

A black and white photo of Lt. Frank H. Moody.
During World War II, the Tuskegee Airmen served as the first African-American fighter pilots for the U.S. military. Some of airmen trained over the Great Lakes, including over Lake Michigan and Lake Huron – and some of them tragically lost their lives during those training exercises. This Tuskegee Airman, Lieutenant Frank H. Moody, crashed into Lake Huron and was killed on April 11, 1944. Researchers from NOAA Thunder Bay National Marine Sanctuary have been working to recover lost Tuskegee aircraft and honor these airmen's legacy. Recently, Moody's airplane was discovered resting in 30 feet of water.
A close-up of a yawning elephant seal.
This sleepy seal needs a power nap! Elephant seals – like this one in NOAA's Monterey Bay National Marine Sanctuary – use lots of energy diving deep underwater to find food while avoiding predators, like white sharks. An elephant seal can dive for up to 30 minutes at a time for months on end, only spending a couple minutes at the surface for a quick breather. Between months of searching for food, breeding, defending their territory, and raising their pups, it’s only fair that elephant seal catch a few Z’s now and again! (Photo: Matt McIntosh/NOAA)

In some parts of the monument, over 50% of the population might only be found in this region! (Photo: James Watt/NOAA)
A close up of a pinkish-white squid in dark waters.
Reef squid – like this one spotted on a night dive in NOAA Florida Keys National Marine Sanctuary – are social cephalopods. One way they communicate with each other is by changing the pigments in their skin, flashing colorful spots and patterns to indicate danger or readiness to mate. If they feel really threatened, reef squid will eject a cloud of black ink to confuse their predators, signaling that they are not squidding around! (Photo: Alexander Neufeld)

James and a dog stand on a beach. James is holding two garbage bags.
"I am fortunate enough to work with volunteers almost on a daily basis. A lot of my volunteers travel hundreds of miles just to come out and clean Washington's beaches, including the numerous ones along NOAA Olympic Coast National Marine Sanctuary. Each year, our volunteers help remove nearly 120,000 pounds of household plastics, lost fishing gear, and other marine debris from the coastal environment. As a collective whole, our efforts are stronger, and our volunteers prove that every time they participate in our cleanups." – James Roubal, program coordinator at Olympic Coast National Marine Sanctuary Foundation and Washington CoastSavers What inspires you about the ocean?(Photo courtesy of James Roubal)
An anemone beginning to eat a crab.
As the saying goes, keep your friends close, and your anemones closer...unless you're a crab. Despite their colorful and flowery appearance, sea anemones – like this one in a NOAA's Greater Farallones National Marine Sanctuary tide pool – are carnivorous predators! A sea anemone’s tentacles can sense even the slightest touch, triggering a rapid sting that paralyzes its prey. Sea anemones commonly snatch up small fish or crustaceans that cross their path. It's been a crabby day for this unlucky crustacean.(Photo: Sarah Heintzelman/NOAA)
A breaching whale.
Whale would you look at that breach? Scientists still aren't quite sure why humpback whales and other species breach, but one hypothesis is that breaching helps whales remove parasites from their skin – similar to the way some land animals scratch their backs against trees. It's also possible that noise levels might impact breaching behavior. When noise levels from rough seas or boats impact a whale's ability to communicate, they may use the sound of their bodies crashing against the water's surface as an alternate method of communication – and use visual cues from above the water's surface to help them direct communication.(Photo: Douglas Croft Images)

 A Hawaiian monk seal mother and pup nap on a beach.
Anyone else in the mood for some beach time? Hawaiian monk seals – found in Hawaiian Islands Humpback Whale National Marine Sanctuary and Papahānaumokuākea Marine National Monument – know how to make the most of a sunny day. Though these seals are one of the most endangered marine mammals in the world, protection efforts by NOAA and our partners have led populations to increase in the past few years. Today, about 1,100 live in the Northwestern Hawaiian Islands, with an additional 300 residing in the Main Hawaiian Islands! It's only fair that occasionally they get to put up their flippers and just take in the sun. 😎 (Photo: Mark Sullivan/NOAA, under NMSF Research Permit #10137)
Ice over a lake at sunrise.
Some icy trivia for you – which national marine sanctuary sometimes freezes over in the winter time? NOAA Thunder Bay National Marine Sanctuary! The ice on this Lake Huron sanctuary is beautiful, but also can be treacherous. In 1875, for example, the schooner Cornelia B. Windiate came to an untimely end during a fall gale. It's thought heavy seas covered the decks in ice, causing the vessel to sink to the bottom of the lake.(Photo: Nick Zachar/NOAA)
A humpback whale underwater.
Whale hello there! Every winter, thousands of humpback whales make their way to Hawaiian Islands Humpback Whale National Marine Sanctuary. In the warm waters surrounding Hawai‘i, these whales mate, calve, and nurse their young. In the sanctuary, mothers can be seen breaching alongside their calves, while males can be seen competing with one another for females in fierce head-to-head battles. Learn more about the sanctuary at hawaiihumpbackwhale.noaa.gov!(Photo: Ed Lyman/NOAA, under NOAA Permit #774-1714)

A lantern with a red lens.
Today marks the anniversary of our nation's first national marine sanctuary, NOAA Monitor National Marine Sanctuary! This small but important sanctuary protects the resting place of the USS Monitor, one of the most famous warships in our nation's history. The ship was regarded as President Abraham Lincoln's "secret weapon" in the Civil War. However, in 1862, Monitor sank while under tow off North Carolina when a fierce storm swamped the low-riding ship. The last anyone saw of Monitor was its red signal lantern rising and falling in the heavy seas. More than a century later, that red lantern was the first artifact recovered by NOAA from the Monitor shipwreck, and it is now on display at The Mariners' Museum and Park in Newport News, Virginia.(Photo courtesy of The Mariners' Museum)

Two Hawaiian spinner dolphins swimming together.
Spin into the weekend with these Hawaiian spinner dolphins in Papahānaumokuākea Marine National Monument! Hawaiian spinner dolphins exhibit a "fission-fusion society," where they fuse into large pods of hundreds as they move offshore at night to feed, then split into smaller groups to rest and socialize during the day. The tranquil, remote waters of the monument are the perfect place for these charismatic dolphins to rest and feed! (Photo: Kevin Lino/NOAA)
A manta ray swimming over a reef, seen from below.
It's a bird, it's a plane – it's a manta ray! Lucky divers in NOAA's Flower Garden Banks National Marine Sanctuary get to see manta rays cruising the reef. Much like our own fingerprints, the spot patterns on a ray's belly are unique to each individual. This helps researchers identify individuals and better understand their habits! (Photo: G.P. Schmahl/NOAA)
A brown and yellow-spotted moray eel looks out from a crevice. This photo was taken in NOAA Florida Keys National Marine Sanctuary.
Who captures fish raw with two sets of jaws? That's a moray! In addition to their "main" set of teeth, moray eels have what are known as pharyngeal jaws. This second set of jaws is within the eel's throat, and helps it swallow its prey. Talk about a predator with serious bite! (Photo: Steve Lonhart/NOAA)

A small white crab with brown stripes in the palm of a person's hand.
Talk about a crab-tivating new friend, and one that fits in the palm of your hand! Just watch out for its claws if it's feeling crabby. This little juvenile red rock crab (Cancer productus) was picked up out of some algae during a research expedition in NOAA's Greater Farallones National Marine Sanctuary. In adulthood, red rock crabs are, indeed, brick red, but when they're this young they can be a variety of colors and patterns. (Photo: Mojoscoast/ACCESS/NOAA/Pt. Blue/R. Wallen)
Close-up on a loggerhead sea turtle's face.
Loggerheads are turtley awesome! Loggerheads get their name from their relatively large heads, which support powerful jaws and enable them to feed on hard-shelled prey. From hatching to adulthood, a loggerhead increases its weight more than 6,000 times! Marine debris, fishing gear, and development near their nesting areas remain major issues for loggerheads, but by working together we can help reduce these threats. This beautiful loggerhead was spotted in NOAA's Flower Garden Banks National Marine Sanctuary. (Photo: G.P. Schmahl/NOAA)
A sea otter at the ocean surface holding a crab in its paws.
Cute AND helping the ecosystem: the sea otter story! Sea otters help stabilize kelp forest ecosystems in places like NOAA's Monterey Bay National Marine Sanctuary. One the sea otter's favorite foods is the purple sea urchin, which is known for eating kelp holdfasts and destroying kelp forests – so by chowing down on urchins, sea otters help protect the kelp. This sea otter is doing double duty, too, by snacking on an invasive green crab, a species that threatens West Coast ecosystems. (Photo: Lilian Carswell/U.S. Fish and Wildlife Service)
A pink jellyfish floating in the ocean over a coral reef.
Don't be jelly of this moon jelly's gorgeous pink hues! These lovely jellyfish are common in NOAA Florida Keys National Marine Sanctuary from August to October. Their sting tends to be mild, but still best to look and not touch! (Photo: Katy Danca Galli)
Bright pink deep-sea corals and basket stars.
Today is International Mountain Day – and some of the largest mountains in the world occur under the sea. Thanks to the steep slopes of these seamounts, nutrients are carried upwards from the depths of the ocean toward the sunlit surface, providing food for corals, fish, crustaceans, and more. One seamount is Davidson Seamount in NOAA's Monterey Bay National Marine Sanctuary, which is 26 miles long, eight miles wide, and 7,480 feet tall! Davidson Seamount supports a lush, biodiverse community of species like the precious coral and basket stars pictured here. (Photo: NOAA/Monterey Bay Aquarium Research Institute (MBARI))
Large male elephant seal resting on grass.
Northern elephant seal, or giant prairie dog? Some of the largest breeding colonies of northern elephant seals occur in NOAA Channel Islands National Marine Sanctuary and Channel Islands National Park – but even an elephant seal competing for a mate needs to take a nap sometimes.

A Laysan albatross stands over an egg, with her wings extended.
Wisdom is back! Wisdom, a Laysan albatross and the world's oldest known bird, has returned to Midway Atoll in Papahānaumokuākea Marine National Monument. She is at least 68 years old – and biologists have confirmed that she has laid an egg! Albatross often take time off to rest between egg-laying years, but the Wisdom and her mate Akeakamai have met on Midway Atoll to lay and hatch an egg every year since 2006. Wisdom has laid between 30 and 35 eggs in her lifetime. In 2017, the chick that she fledged in 2001 was observed just a few feet away from her current nest, marking the first time a returning chick of hers has been documented.Please join us in welcoming Wisdom home!

A reef with large umbrella-like coral atop other corals.
Can you name a more iconic duo than corals and their tiny single-celled algae partners? Called zooxanthellae, these small algal cells provide food for corals by transforming sunlight into nutrients. Coral polyps use food that the algae leak out as an energy source to grow and flourish, like this reef-building community in NOAA National Marine Sanctuary of American Samoa! The algae also provide corals' brilliant colors. Because the algae are key to healthy coral reefs, this is also why we mostly find reef-building corals in waters that have adequate access to sunlight. (Photo: The Ocean Agency/XL Catlin Seaview Survey)
Arms of a red brittle star poking out of a coral and wrapped around tiny eggs.
Each year, the coral colonies of NOAA's Flower Garden Banks National Marine Sanctuary take part in mass spawning events, releasing gametes that can drift on the current, settle elsewhere, and start new coral colonies. These spawning events can be a spectacular sight to see! Other marine creatures, like this brittle star, also partake in the festivities by stealing away some gametes to eat. Since there are billions of these tiny gametes cascading underwater during this annual event, this sneaky brittle star gets a pass 😎 (Photo: Emma Hickerson/NOAA)
A round yellow coral with a barren patch that shows the coral skeleton.
In the past few years, something has been targeting the corals in and around NOAA Florida Keys National Marine Sanctuary. In 2014, scientists started noticing patches of corals that were white and skeletal, with no living tissue. This disease, termed "stony coral tissue loss disease," has since spread over 150 square miles. Sanctuary scientists and partners are working to understand what is causing this disease and how it can be stopped – right now, they know that it seems to be transmitted by touch and water circulation. If you visit the sanctuary, you can help protect corals by using mooring buoys to avoid anchoring on and damaging corals, using reef-friendly sunscreens, cleaning your dive gear, and never, ever touching corals. Learn more about the disease and other ways you can help. (Photo: Nick Zachar/NOAA)
Metallic-colored fish swimming in front of coral reef.
Coral reefs are havens for many marine animals, like this giant trevally, or ulua in Hawaiian! In Papahānaumokuākea Marine National Monument, coral ecosystems are kept relatively isolated from human contact in an effort to keep reef diversity undisturbed. The incredible ecosystems of the monument include species that are found nowhere else in the world. More than 50 percent of the fish species and 30 percent of the corals in the Northwestern Hawaiian Islands are found only in the waters around Hawai‘i!(Photo: Greg McFall/NOAA)
Bottom-up perspective of corals and other invertebrates.
The coral ecosystems in our national marine sanctuaries and monuments are unbereefable! Your National Marine Sanctuary System is home to diverse coral ecosystems, ranging from the tropical waters of Papahānaumokuākea Marine National Monument to the deep waters of NOAA's Monterey Bay National Marine Sanctuary. We’ll be sharing these marvels of the sea all week long, so stay tuned! Here, a towering coral reef assemblage reaches to the surface in NOAA Florida Keys National Marine Sanctuary. (Photo: Beata Lerman)
Two orange, black, and white striped fish swim over a large sea anemone.
We found Nemo! A special mucus layer on anemonefish – like these two in NOAA National Marine Sanctuary of American Samoa – allows them to live among anemones without being stung. In return for the protection the anemone provides, the anemone gets food leftovers from the fish. Plus, the anemonefish is quite protective of its home, so it chases away anything that might be interested in chowing down on the anemone! (Photo: Greg McFall/NOAA)

Learn more about what you can do at the sanctuary nearest you. (Photo: Nathan Coy)
Close-up of a orange fish with big eyes and spikes on its back, lying on the ocean floor.
Don’t let those adorable eyes fool you, this balloonfish doesn't mess around! Balloonfish, like this one in NOAA Florida Keys National Marine Sanctuary, have highly elastic stomachs that allow them to ingest large volumes of water, making them too big to be eaten by potential predators. Plus, when they expand, those long, sharp spikes stick straight out – not a pleasant mouthful! (Photo: Daryl Duda)
Two yellow birds facing each other atop a green glass sphere-like object, with other glass spheres covering the shore.
Laysan finches are endemic to the Hawaiian Islands. Lacking substantial predators both on ground and in the skies, these birds have little to fear and readily approach other creatures, including humans! Man-made objects, such as these glass fishing floats washed ashore on Papahānaumokuākea Marine National Monument, also attract their curiosity, but sometimes that curiosity can lead these birds to trouble. Laysan finches have been found trapped in tents, under tarps, and even in pit toilets. Help keep these birds safe by always disposing of your waste properly – trash travels! (Photo: Koa Matsuoka)
Tomol paddlers on the ocean at sunrise.
Each year, members of the Chumash community journey from the California mainland to Limuw, or Santa Cruz Island. Paddlers, or pullers, voyage using a tomol, a traditionally-built redwood plank canoe. It has a six-person crew, and unique abalone inlay designs. Along their way, the pullers travel through NOAA Channel Islands National Marine Sanctuary. They are supported by the sanctuary's Research Vessel Shearwater, which sets course, hosts resting paddlers, and helps protect the tomol and its pullers from vessel traffic. Read one tomol puller's story. (Photo: Robert Schwemmer/NOAA)
A diver swimming through the water.
Dive into NOAA Florida Keys National Marine Sanctuary, you never know what you might discover! Sometimes, recreational divers and fishers stumble upon pieces of historical shipwrecks and other artifacts on the seafloor. Fisherman Jose Antonio Lopez Ruiz of Homestead, Florida, is credited with finding this wooden wreckage from an unidentified 19th century sailing ship near Alligator Reef near Islamorada. He did the right thing by reporting the find and not disturbing it! Here, volunteer Cassie Qualls returns to the surface after investigating the wreckage. Florida Keys National Marine Sanctuary encourages anyone who happens across new discoveries to get in touch, so these artifacts can be studied to reveal rich stories about our maritime past!

A person lies on her paddleboard, floating above an underwater shipwreck.
One more day of relaxation before it's back to work! Here, a stand up paddleboarder takes a break above the wreck of the shipwreck Albany. One of the more shallow wrecks in NOAA Thunder Bay National Marine Sanctuary (only five feet deep!), Albany is an excellent wreck to explore by paddleboard, kayak, or snorkel. (Photo: Bryan Dort)
Two dolphins swimming at the water's surface.
Atlantic white sided dolphin: "I’m not so sure I can do it..." Also Atlantic white sided dolphin: *leaps out of the water like a magnificent acrobat* Atlantic white sided dolphins are capable of impressive jumps and breaches, even earning the nickname “springer” and “jumper." These marine mammals can be spotted in the temperate waters of NOAA's Stellwagen Bank National Marine Sanctuary and across the North Atlantic. (Photo: Mackenzie Maier)
 A dark orange and white striped fish with large fins.
Tired of turkey already? What about the turkeyfish? Also known as the lionfish, its fins resemble the colorful plumage of a turkey. In recent decades, this fish has become an invasive species in Atlantic waters, including in NOAA's Flower Garden Banks National Marine Sanctuary. With a voracious appetite, rapid reproduction, and no known predators, it is a significant threat to biodiversity and reef health. One management method is to eat them! So, if you’re feeling seafood for a post-Thanksgiving treat, why not give the turkeyfish a try? (Photo: Bess Bright)

This Thanksgiving, we are thankful for all the people who support the National Marine Sanctuary System, and all the creatures who live in these protected waters! From the photographers who bring the ocean to our fingertips, to humpback whales who majestically swim through these waters, and everyone in between, thanks for making our national marine sanctuaries and marine national monuments spectacular! What marine critters are you thankful for? Let us know in the comments! (Photo: Douglas Croft Images)
Two elephant seals fighting on a beach.
Every winter, the beaches of NOAA's Greater Farallones National Marine Sanctuary and other sanctuaries along the West Coast transform into a mating ground for elephant seals. Males battle it out for territory in quick clashes that rarely result in lasting damage. Soon after, the females arrive to breed, and will spend a month on land raising their pups before voyaging back to the sea. These elephant seals are lots of fun to watch, but make sure to give them lots of space – an elephant seal selfie is NOT a good idea! These huge seals can be dangerous, and when you get too close you can stress them during a critical time in their life. (Photo: Sara Heintzelman/NOAA)
A young bird with brown plumage, green legs, green around its yellow eyes, and a pink bill leans forward.
Just a liiiiittle farther...What do you think this juvenile green heron is reaching for? One of the simple joys we can all enjoy in national marine sanctuaries is birdwatching! No matter your age, skill, or location on land or sea, we can all enjoy some pretty incredible birding experiences in sanctuaries. In NOAA Florida Keys National Marine Sanctuary, mangrove-fringed islands provide nesting grounds for a number of bird species. Plus, juvenile fish among the mangrove roots give these birds plenty of food to snack on. (Photo: David J. Ruck/NOAA)
Sea turtle resting among invertebrate-covered rocks.
Dive in NOAA Gray's Reef National Marine Sanctuary, and you might encounter loggerhead sea turtles! These turtles visit the sanctuary to rest and forage. As with all wild animals, always give loggerhead sea turtles plenty of space. Even if you're not near the sanctuary, you can help protect these threatened sea turtles by properly disposing of your trash and recycling when possible – plastic in the ocean can be easily mistaken for food! Learn more about safeguarding sea turtles in Gray’s Reef. (Photo: Greg McFall/NOAA)
Historical black and white photo of two officers standing aboard a war vessel.
Before the USS Monitor sank and became protected by NOAA Monitor National Marine Sanctuary, it served as a powerful Union vessel during the Civil War. In 1862, the ironclad warship took to the waters of the East Coast for a series of battles against Confederate crews. In the end, though, it was the forces of nature that brought Monitor down to the ocean floor. Learn more about the Monitor's history. (Photo: The Library of Congress)
A close-up of a bat ray swimming across the ocean floor.
Rays like this bat ray in NOAA Channel Islands National Marine Sanctuary are searayiously cool! There are many different types of sea rays, and each are known for their flattened bodies.

A close up of a manatee staring directly at the camera.
Why, hello there! Today is the 28th anniversary of NOAA Florida Keys National Marine Sanctuary, and what better way to celebrate than with Florida’s state marine mammal, the manatee? These marine grazers can weigh up to 3,000 pounds as fully grown adults, and can consume nearly a tenth of their own weight in water grass, algae, and other vegetation in just a day! If you're visiting the Keys, make sure to slow down in manatee habitat to avoid colliding with these slow-moving animals. (Photo: Keith Ramos/U.S. Fish and Wildlife Service)
A white and orange sea slug on algae.
Stop clowning around! This little nudibranch, spotted in NOAA's Cordell Bank National Marine Sanctuary, is none other than the sea-clown triopha.

A diver hovers over a shipwreck.
Flash back to October 23, 1868: the two-masted schooner F.T. Barney was sailing the waters of the Great Lakes. But en route from Cleveland to Milwaukee, it was hit by the schooner T.J. Bronson. In less than two minutes, Barney sank to the floor of Lake Huron – but miraculously, no lives were lost. Today, the wreck is protected as part of NOAA Thunder Bay National Marine Sanctuary, and remains one of the most complete wrecks of its kind. (Photo: Tane Casserley/NOAA)
A dark colored dolphin leaping out of the water.
I believe I can fly! *splash* False killer whales like this one in Papahānaumokuākea Marine National Monument are very social marine animals. As their name implies, though they look a bit like orcas, they're an entirely separate species of dolphin. They are often spotted in small groups of a few individuals, but when they capture prey they will converge and share the meal. Learn more about false killer whales. (Photo: Jim Cotton/NOAA)
A seal poking its head above the water.
We’re sealriously obsessed with gray seals like this one in NOAA's Stellwagen Bank National Marine Sanctuary! While gray seals may appear approachable in the wild, human interference is a major threat to these marine mammals. Fishing entanglements, watercraft strikes, and interactions with humans put them at risk. Help protect gray seals by keeping a safe distance and not approaching them too close on land or on water.

A bright orange fish swimming through a kelp forest.
Meet the fiery state fish of California: the Garibaldi. This feisty fish is found across the California coast and is a common sight in the kelp forests of NOAA Channel Islands National Marine Sanctuary. In the spring, male Garibaldis are responsible for creating and defending nests that might attract a female garibaldi to lay her eggs in. However, these fathers-to-be are unforgiving to trespassers, chasing out intruders that inch too close, which includes the female garibaldi after she’s laid her eggs! (Photo: Claire Fackler/NOAA)
A school of yellow fish swim across a reef.
There’s notang brighter in the sea than the yellow tang! These radiant fish are reef dwellers that thrive in Pacific waters, like those in Hawaiian Islands Humpback Whale National Marine Sanctuary. Some have been recorded to live for up to 30 years in the wild! (Photo: Claire Fackler/NOAA)
A large shark swims in front of a shipwreck.
With their ragged, protruding teeth, sand tiger sharks may look fearsome, but they're actually quite docile! You can often spot them when diving on shipwrecks in the Graveyard of the Atlantic like the USS Tarpon, pictured here. Wrecks support bountiful populations of small fish and invertebrates, key snacks for the sand tiger shark! The USS Tarpon is one wreck that could be protected by the proposed expansion of NOAA Monitor National Marine Sanctuary. (Photo: Tane Casserley/NOAA)
A humpback whale jumps above the ocean’s surface with water splashing above its head.
Whale, whale, whale, what do we have here? This energetic humpback whale spotted in NOAA's Monterey Bay National Marine Sanctuary is exhibiting a common whale activity known as breaching. There are many possible motivations for these acrobatic leaps above the water’s surface, including communication with other whales, attracting mates, or just being playful. Humpback whales sure know how to make a splash! (Photo: Douglas Croft Images)
A school of tuna fish with shiny bodies swim below the sea’s surface.
NOAA's Greater Farallones National Marine Sanctuary is home to a fintastic ocean predator: the Pacific bluefin tuna! Pacific bluefin tuna like to feed on squid and smaller fish such as herring and mackerel. And they’re no stranger to the wide open seas, migrating thousands of miles each year to either feed or spawn. They're one of the most impressive fish in the entire tunaverse!(Photo: NOAA)
A close up of the face of an orange fish with a large mouth.
Oyster toadfish, like this one in NOAA Gray's Reef National Marine Sanctuary, have a voice unlike any other marine creature! By vibrating their swim bladder muscles, males from this bottom-dwelling species let out foghorn-like calls to serenade nearby females during mating season. Toadally charming, eh? (Photo: Greg McFall/NOAA)
Two young people watching a whale surface.
Happy birthday to NOAA's Stellwagen Bank National Marine Sanctuary and Hawaiian Islands Humpback Whale National Marine Sanctuary! Designated on this day in 1992, these national marine sanctuaries were created to protect critical habitat for humpback whales. Humpbacks and other endangered whales flock to Stellwagen Bank off Cape Cod to feed, while Hawaiian Islands Humpback Whale shelters humpbacks every winter as they breed and calve their young in the waters of Hawai‘i.

All hail the mighty krill! Despite their tiny size, these shrimp-like crustaceans are powerhouses for ocean ecosystems, serving as a food source for whales, seabirds, fishes, and other marine life. Krill like this one from NOAA's Cordell Bank National Marine Sanctuary congregate as they swim, making it easy for predators to scoop them up. Occasionally, massive swarms can be viewed from outer space! (Photo: Sophie Webb/NOAA)
Several dark grey whales leaping out of the water.
Dive into the weekend with these melon-headed whales!

Our love for the ocean is manta be! Today marks the 46th birthday of the National Marine Sanctuary System. Today, we serve as the trustee for a network of underwater parks encompassing more than 600,000 square miles of marine and Great Lakes. It's been a pleasure to serve as stewards for our special marine and Great Lakes places, and we're looking forward to everything to come. Please help us celebrate by sharing your favorite sanctuary memories in the comments! (Photo: Beata Lerman)
A humpback whale diving beneath the ocean surface.
The whales are soon to return to Hawaiian Islands Humpback Whale National Marine Sanctuary! Each winter, thousands of humpback whales journey down to the warm, shallow waters around the Hawaiian Islands. Here between November and May, they breed, give birth, and raise their young. Whale watching during this time is spectacular, and tons of fun. Just make sure to give whales plenty of space – stay back at least 100 yards. Get tips for responsible whale watching.

"At our house our recycling bin is always twice as full as our garbage bin and we are participating in local movements to reduce single-use plastic straws and bags. And whenever we are outdoors, whether it's at the beach or just walking around town, we try to pick up litter as we go." – Craig Wanous, Florida Keys Eco-Discovery Center manager What inspires you about the ocean?

There’s nothing like seeing a bright and healthy coral to uplift your Thursday! Bereef it or not, cauliflower corals like this one in Papahānaumokuākea Marine National Monument aren't actually plants, but animals. Each coral structure is actually a colony of tiny, tiny animals called polyps. These polyps build hefty skeletons, which build up to create a strong coral reef.

White dolphin's head sticking out of the water.
Like many of us, this albino Risso's dolphin is a big dolfan of Monterey Bay National Marine Sanctuary! This juvenile was first spotted with its mother in the sanctuary in 2014, and has been seen occasionally ever since, including earlier this year. (Photo: Douglas Croft Images)
A research diver holding a metal rod while hovering over a shipwreck.
Despite sometimes tragic stories, shipwrecks can serve as habitat for diverse marine life – and can be an amazing place to dive. In NOAA Florida Keys National Marine Sanctuary, an estimated 1,000 wrecks lie scattered on the ocean floor. One of those is the wreck of Benwood, which sank in 1942, pictured here. Have you explored one of the shipwrecks within the sanctuary? We highly wreckommend it! (Photo: Brenda Altmeier/NOAA)

It appears this sailor got a bit too carried away (literally)! Velella velella, or by-the-wind-sailors, drift across the open seas using their chitinous “sails,” which poke above the water’s surface. Despite their free-floating existence, it is not uncommon to find large numbers of Velella velella washed ashore, especially during a bloom. This by-the-wind-sailor jelly was found off the shores of NOAA Olympic Coast National Marine Sanctuary and Olympic National Park. (Photo: National Park Service)
A golden eagle in flight
A few summers ago our camp of 26 youth and four staff settled down by Monterey Bay National Marine Sanctuary to enjoy lunch. It was a beautiful, calm day. Just as we were about to break into our sandwiches, a golden eagle came speeding only a couple of feet off the beach, and took out a duck in a poof of feathers. Amidst the squawking and flurry of the other birds escaping, thirty of us sat with sandwiches in hand, mouths hanging open. We watched as the golden, after a moment, laboriously took back to the air weighted down by it's limp prey. It flew to a cliff within full sight and began plucking it's lunch as the rest of us excitedly recovered and eventually enjoyed our own lunches with this unexpected guest. You just never know when a spectacular experience like this is going to occur, but the more we protect our resources the better we can ensure that these moments are not too far and few between.

 A dark red squid hovering above the seafloor.
A kraken of the depths? Though this Pholidoteuthis adami squid may look devilish, it's actually just trying to blend in with its surroundings. Red light is the first color of light to be filtered out by water, and by the time you get down to the deep sea, the only light available is blue. That blue light doesn't reflect off red animals, so they're much more difficult to see by predators and prey alike! That is, unless you're exploring the ocean with a remotely operated vehicle equipped with bright white lights. (Photo: NOAA Office of Ocean Exploration and Research)
Small, dark red squid in ocean surrounded by white floating particles.
Beware! The vampire squid is here to devour your...marine detritus? We squid you not! Despite its sinister name, the vampire squid is only a scavenger, feeding on the “marine snow” that floats throughout the water column. Instead of ejecting ink, this deep-sea dracula will squirt a bioluminescent mucus towards would-be predators if threatened. Talk about a sticky squiduation! This juvenile was spotted in the deep waters of Monterey Bay National Marine Sanctuary. (Photo: NOAA/Monterey Bay Aquarium Research Institute (MBARI))
Nautilus with red and white hard shell floating through water, with some corals beneath it.
Before rocket engines used jet propulsion, there was the nautilus! Nautili maneuver through the ocean by expelling water from chambers in their hard external shells. In addition to this unique hard shell, the nautilus can have up 90 tentacles, beating its distant cousins, the octopus and the squid, by far. Check out this nautilus swimming through NOAA National Marine Sanctuary of American Samoa. (Photo: Michelle Johnston/NOAA)
Orange octopus with eyelids closed hunkered down between sediment formations.
Happy Octopus Day! This sleepy cephalopod appears to have a case of the Mondays. But don’t be fooled, as octopuses like this one in the Gulf of Mexico are highly agile and attentive creatures. Octopuses have the largest brain of any invertebrate – and more than half of their 500 million neurons are located throughout their eight arms. These cephalopods are equipped for quick action, whether they are stealthily hunting prey or defending themselves from likely predators.

A kayaker only a few feet away from a spyhopping humpback whale. The whale appears to be looking at the kayaker.
DON'T BE THAT GUY! Humpback whales need your help. Right now, whales are feeding close to shore in Monterey Bay National Marine Sanctuary. While it can be tempting to get close to these amazing animals, when you approach them you encroach on the space they need to catch anchovies and other prey. Plus, you put yourself in danger – a humpback whale can weigh more than 50 tons, and you don't want that weight accidentally slamming in to you as a whale breaches or lunges to the surface to catch its prey. If you're as close as this kayaker is to a whale, you are WAY TOO CLOSE. As a rule of thumb, stay 100 yards away from whales; do not cross in front of them, pursue them from behind, or surround them. If you're approached by a whale, drift until the whale moves away. And if you see someone approaching a whale, speak up! Tell others to give the whales plenty of space, and you can report whale harassment or injury to the NOAA Enforcement Hotline at 1-800-853-1964. (Photo: Douglas Croft Images)

A resting sea otter wrapped in kelp.
Ready to nap the weekend away? So is this sea otter in Monterey Bay National Marine Sanctuary! Sea otters often wrap themselves up in a nice little blanket of kelp to keep them from drifting too far while they take a quick snooze. If you're exploring the sanctuary or other areas with sea otters, make sure to give them plenty of space. While it's tempting to get a closer view of the adorable floof that is a sleeping otter, they need their rest! Each time you approach an otter, you're interrupting the time it needs to rest, feed, or otherwise maintain its health. (Photo © Monterey Bay Aquarium)

A sea otter rests on the ocean surface, wrapped in kelp.
We're pawsitively thrilled at this week is Sea Otter Awareness Week! These otterly amazing creatures have made an incredible comeback all along the West Coast, including in places like Monterey Bay National Marine Sanctuary. After extensive hunting in the 1700s and 1800s, only about 50 otters were left in California. Thanks to conservation efforts, there are now nearly 3,000! You can help these cuties thrive by giving them plenty of space when you're exploring the California coastline. Though it may be tempting to get close, each human-otter interaction takes away valuable time sea otters would otherwise spend resting, socializing, or eating. (Photo © Monterey Bay Aquarium)

"I grew up playing on the beach at my family's waterfront cabin on the Hood Canal in Washington, so the ocean, tide pools, and salt water was a huge part of my childhood. As I got older I knew that I wanted to help protect places like that so that future generations could find the same kind of adventure and experiential learning I did as a child. Because I work with K-12 students so much, I try and make sure that I'm an environmental role model to them." – Christine VanDeen, NOAA Olympic Coast National Marine Sanctuary AmeriCorps service member What inspires you about the ocean?

A leatherback sea turtle swims at the ocean surface.
Why should you reduce your use of plastic and always dispose of your trash properly? Well, for one thing, you'll be helping to protect marine animals like this leatherback sea turtle! One of the major issues with plastic in the ocean is that it's easily mistaken for food by hungry animals. Leatherback turtles like this one in Monterey Bay National Marine Sanctuary, for example, primarily eat jellies. And a plastic bag floating on the ocean surface looks a lot like one of those jellies! So always strive to reduce, reuse, recycle – and refuse! By reducing how much plastic we use, we help these sea creatures live long and healthy lives. Find resources to help you go DebrisFree.

A view of a humpback whale from behind. Rope is wrapped around its tail.
Marine debris can have impacts no matter its size, from microplastics to large debris. Fishing gear, for example, can entangle large marine mammals like this humpback whale in NOAA Hawaiian Islands Humpback Whale National Marine Sanctuary. Fortunately, teams of intrepid individuals are on the scene to help whales like this one. In Hawai‘i, the Hawaiian Islands Entanglement Response Network is a partnership of government state agencies, tour operators, fishers, and more who work together to free whales. This collaboration has freed more than 23 whales from entangling gear! If you see an entangled whale or other animal, please don't try to disentangle it yourself! These are large, wild animals that may be scared or panicked, and you put both yourself and the whale in danger by getting into the water with it. Instead, contact your local marine mammal stranding network.(Photo: Ed Lyman/NOAA, under MMHSRP permit #932-1489)
An aerial photo of the coastline in NOAA National Marine Sanctuary of American Samoa
Ah, the beauty of a crystal clear sea – but is it really so clean? When we think of trash and plastic in the ocean, many of us picture big piles of large debris floating on the ocean surface. But the truth is that most of the plastic in the ocean is so small we can't even really see it. We call this microplastic. Plastic doesn't biodegrade; instead it breaks down into tiny, tiny pieces. Microplastics have been found in the stomachs of many marine organisms, from plankton to whales, and they can leach contaminants into the water. Because they're so small, they're incredibly difficult to remove from the ocean – you can't just scoop them out easily! So one of the best ways to stop microplastics from affecting our ocean is to keep plastics out of the water in the first place. What choices will you make today to help keep debris out of the ocean? Let us know in the comments! (Photo: Matt McIntosh/NOAA)
Many plastic bottle caps jumbled together after being picked up off a beach
Take a minute to think about the plastic you've used so far today. Did you get your coffee in a to-go cup with a plastic lid? Grab lunch takeout from the restaurant down the street? Get a plastic bag from the grocery store? Plastics are, of course, useful, but many of them end up in the trash and in the ocean. Because plastics don't biodegrade, they can persist in the environment for a long, long time. There, they can leach chemicals into the ocean, be mistaken for food by marine animals, and entangle marine life. The good news is that you can help! Say no to single-use plastic, recycle whenever possible, and get involved in local beach and watershed cleanups, and you can help keep our ocean and waterways clean and healthy. This week, we'll be bringing you information about marine debris and how you can help solve this problem. What questions do you have about trash in the ocean? (Photo: NOAA)
An underwater view of Gray's Reef, with fish swimming above a seafloor covered in invertebrates. A diver swims behind the fish.
"I came to work for NOAA Gray's Reef National Marine Sanctuary because I believe that in order to help preserve the biodiversity of our planet, we need healthy wilderness habitats. Our ocean offers the greatest example of wilderness but with the added challenge of remoteness. These habitats are harder for humans to reach and less known, but are equally impacted by human actions. Having a job that offers me the opportunity to make connections for people with the natural world is inspiring and a gift." – Jody Patterson, Gray's Reef National Marine Sanctuary events and volunteer coordinator What inspires you about the ocean?

A dead Laysan albatross chick that has been dissected to show a stomach full of small plastic pieces.
Plastic trash can travel through watersheds and throughout the ocean. There, it breaks down into smaller pieces that animals may easily confuse for food. This is particularly a problem for seabirds like Laysan albatrosses, which skim the ocean surface for food and pick up plastic along the way. They then regurgitate the plastic to their chicks, who cannot digest it and may die as a result. This Laysan albatross – and many others like it – was born on Kure Atoll in Papahānaumokuākea Marine National Monument, which is largely uninhabited and located more than a thousand miles from any major city. It died with a stomach full of debris. Your trash travels, so make sure to clean up after yourself and others to help keep wildlife safe and healthy. (Photo: Claire Fackler/NOAA)
A stony coral releasing gametes.
Corals are stationary animals that build hard skeletons to protect their colonies. So how do they reproduce and ensure the genetic diversity of future generations? Earlier this month, the reef-building corals of Flower Garden Banks National Marine Sanctuary spawned, releasing reproductive material into the water column where it has the opportunity to mix and produce larvae. Those larvae will drift along in the ocean until they find a suitable place to settle, and there they'll grow into a new generation of corals! (Photo: Emma Hickerson/NOAA)

White sea anemones cling to an underwater cliff.
Rocky reefs within Olympic Coast National Marine Sanctuary provide habitat for fish, invertebrates, seaweeds, and more. The giant plumose anemone is common on vertical walls, where they filter water for food. These anemones can reach three feet in height when their tentacles are fully extended!
A small blue and yellow damselfish swims over a sponge.
"I once had a single, small damselfish follow alongside me for whole hour as I swam across a bay from end to end. I'm not sure why it behaved that way – maybe it was habituated to people and thought I would feed it, or maybe it was just using me for cover from a reef shark that was also hanging around the area at the time. Regardless of the reason, the companionship struck me and the memory has lasted for years. It reminds me that every interaction we have with the natural world, even something as unassuming as a snorkel excursion, can affect some piece of that ecosystem – not necessarily in an obviously negative or positive way. You are always more than a spectator, whether you mean to be or not. I believe we all have a duty to be conscious of that implied responsibility." – Chiara Zuccarino-Crowe, Michigan Sea Grant outreach coordinator (Photo: Greg McFall/NOAA)

A translucent baby squid with red dots swims in a dish of water.
What are the speckles on this baby squid? Chromatophores! Chromatophores are special pigmented cells that enable squid, octopuses, and cuttlefish to rapidly change color and texture. This color-changing skill helps them camouflage themselves with their surroundings, and also assists with communication. This baby squid was found in Greater Farallones National Marine Sanctuary by researchers with the ACCESS Partnership. ACCESS conducts regular monitoring expeditions within national marine sanctuaries in California to better understand habitat and ecosystem conditions. (Photo: Ryan Anderson/NOAA/Pt. Blue/ACCESS)

More than 200 species of fish seek shelter and food in Gray's Reef National Marine Sanctuary – including belted sandfish like these. Here in this rocky area off the coast of Georgia, you'll find fish, sponges, crabs, soft corals, and more! (Photo: Greg McFall/NOAA)
A white humpback whale flipper reaching out of the ocean.
Humpback whale flippers are huge – up to one-third the length of the whale's body! These flippers are what inspired its scientific name, Megaptera, which means "big-winged." (Photo: Ed Lyman/NOAA, under MMHSRP Permit #20311)
A closeup view of a leatherback sea turtle's head while it swims at the ocean surface. A sea nettle tentacle is hanging out from the corner of its mouth.
Did you know the largest sea turtle in the world can be found in Monterey Bay National Marine Sanctuary, just off the coast of California? Leatherback sea turtles like this one can be more than six feet long and weigh more than 2,000 pounds. These huge turtles have a big appetite for jellyfish – look closely, and you can see the tentacles of a sea nettle jelly hanging out of this one's mouth. That food preference puts them especially at risk from marine debris, as floating plastic bags and other plastics look remarkably like swimming jellies. Help protect these endangered sea turtles and always dispose of your trash properly! (Photo: Douglas Croft Images)

A hawksbill sea turtle swims through a coral reef.
This hawksbill sea turtle in National Marine Sanctuary of American Samoa is cruising through Turtle Tuesday. Sea turtles may seem to move slowly, but their flippers make them efficient swimmers and they can migrate thousands of miles across the globe. Who knows where this sea turtle will travel next?

Anna (left) and Stellwagen Bank National Marine Sanctuary research coordinator Dr. David Wiley examine a shearwater that Wiley is holding.
"I am really proud to be affiliated with the great shearwater research program in Stellwagen Bank National Marine Sanctuary as a Dr. Nancy Foster Scholar. The team tags birds with satellite tags each summer while taking a wealth of other data and samples from each tagged individual, and has so far identified some important trends in seabird habitat use and feeding preferences. This tagging work is both novel and highly valuable for fisheries management and seabird ecology. The team also gets to use fish gut catapults and other ingenious field gear to make the tagging happen, obviously making these research trips a big highlight of my year!" – Anna Robuck, Dr. Nancy Foster Scholar & URI Graduate School of Oceanography Ph.D. student (Photo: NOAA)
A purple and brown giant clam attached to rocks and corals.
Check out this beautiful purple giant clam in NOAA National Marine Sanctuary of American Samoa! Once nestled into a location on the reef, giant clams remain stationary throughout life, and play a major role in reef community structure. Like corals, giant clams have developed symbiotic relationships with algae called zooxanthellae. In return for shelter, zooxanthellae provide giant clams with nutrients they've photosynthesized.

A cormorant in flight.
Cormorants are just one of many varieties of seabird found in sanctuaries like Channel Islands National Marine Sanctuary. But unlike many seabirds, cormorant feathers aren't coated in a waterproofing oil. That means these birds have to spend much of their time sunning themselves and drying their wings. (Photo: Robert Schwemmer/NOAA)
A right whale surfaces so that part of its head is visible. A small seabird rests on the ocean surface in front of it.
Get a close-up glimpse of this North Atlantic right whale's baleen! Many whales have hundreds of plates of keratin – the same material that makes up your fingernails – that hang down from their upper jaw. These plates are known as baleen, and act like a strainer. The whale takes in a big gulp of water (and krill or fish), closes its mouth, pushes the water out through the baleen, and then slurps down the krill or fish left behind in its mouth. That way they get a belly full of food, and not saltwater! Each year, North Atlantic right whales travel north to Stellwagen Bank National Marine Sanctuary off the coast of Massachusetts to feed. North Atlantic right whales are one of the most endangered marine mammals in the world, with only a few hundred left. Find out how the sanctuary is helping to protect them. (Photo: Peter Flood)
A researcher holds up a sieve filled with zooplankton. Another researcher kneels on the ship deck behind her. Both are smiling at the camera.
How do researchers track ecosystem health in our West Coast national marine sanctuaries? With regular surveys! The ACCESS Partnership supports marine wildlife conservation and healthy marine ecosystems by conducting regular ocean research throughout Greater Farallones National Marine Sanctuary and Cordell Bank National Marine Sanctuary. The data we collect helps resource managers understand ocean conditions and how they're changing over time. Here, Cordell Bank National Marine Sanctuary research coordinator Danielle Lipski (right) and student intern Grace Kumaishi (left) process zooplankton samples that were collected from 100 meters below the ocean surface.

A Hawaiian monk seal swims underwater and looks at the camera.
Why hello – I didn't seal you there! This curious pinniped is none other than a Hawaiian monk seal, or ilio-holo-i-ka-uaua in Hawaiian. Though they are one of the most endangered marine mammals in the world, there is some good news -- populations have increased by three percent annually for the past three years thanks to work by NOAA and our partners. Today, about 1,100 live in Papahānaumokuākea Marine National Monument, while an additional 300 reside in the Main Hawaiian Islands. If you see a Hawaiian monk seal on the beach or in the ocean, please let us know so we can better understand and track this endangered species! Get more info on how to how to report sightings.

Two kayakers talking to one another.
Volunteers help make sanctuaries fantastic places to visit and play. In Monterey Bay National Marine Sanctuary, for example, Team OCEAN volunteers are trained naturalists who kayak throughout the sanctuary. These naturalists serve as docents on the water, teaching visitors about respectful wildlife viewing and the incredible ecosystems of the sanctuary. (Photo: Amity Wood/NOAA)

A brain coral releases egg bundles.
Every August, seven to 10 days after the full moon, the reef-building corals within the sanctuary put on a fantastic spawning display, onTA brain coral releases egg bundles.e of the most abundant displays in the entire Caribbean. Most scientists agree that these mass spawning events are designed to allow genetic mixing and dispersal of offspring over large distances. Plus, the sheer volume of the events allow for the fertilization and survival of a significant number of larvae despite the best efforts of predators. (Photo: G.P. Schmahl/NOAA)
A snorkeler swims beneath the water, just above the wooden remains of a shipwreck.
Located in Lake Huron, Thunder Bay National Marine Sanctuary protects one of the best-preserved and nationally-significant collections of shipwrecks in the United States. Here, a snorkeler explores the wreck of the two-masted schooner Portland, which sank in 1877. While many of the wrecks within the sanctuary are deep and only accessible by divers, Portland rests in a shallow area only six feet beneath the surface. That makes it easy to explore while snorkeling or kayaking! (Photo: David J. Ruck/NOAA)
A sea lion leaps out of the ocean near a beach. Additional sea lions are hauled out on the beach behind the leaping sea lion, and another sea lion is at the ocean surface in the foreground watching it.
Wheeeeee! This California sea lion is having a blast leaping out of the water in Channel Islands National Marine Sanctuary. What do you think the sea lion in the foreground thinks of all this revelry? (Photo: Jeff Harris/NOAA)
Humpback whales lunge feeding at the ocean surface. Small fish are jumping through the water to try to escape.
Feeding frenzy! Each summer, humpback whales are drawn to Monterey Bay National Marine Sanctuary for its abundance of food sources like anchovies. Humpback whales use a number of feeding techniques, including lunge feeding, pictured here. When lunge feeding, a whale moves quickly toward the surface and opens its mouth, taking a huge gulp of water so its throat pleats expand. It then closes its mouth and pushes the water out through its baleen, filtering the water so that fish and krill are left behind in its mouth. Yum!(Photo: Douglas Croft Images)
A large rock overlooking the ocean. The rock has honeycomb-like depressions in its surface.
A fossilized wasp nest in Greater Farallones National Marine Sanctuary? Not quite! This is a tafoni formation, also known as honeycomb weathering. The divots are created over time when salty air and saltwater hit sandstone and collect in small depressions on the rock. (Photo: Sara Heintzelman/NOAA)
Three people on an inflatable boat holding their hands up in celebration; the boat is holding piles of nets and other debris.
"Before I was the Papahānaumokuākea Marine National Monument superintendent, I served as a member of a multi-agency team that spent a month in the monument removing nets and other discarded debris from the reefs and islands. We spent hours each day searching for and removing nets tangled on reefs that could have been entanglement hazards for all the protected and unique species that inhabit these remote islands. In a month we pulled over 20 tons of nets, buoys, line, and other debris off the reefs and shorelines. It was an incredibly rewarding experience and a daily reminder of why we need to do all we can to keep our ocean clean and healthy." – Athline Clark, Papahānaumokuākea Marine National Monument superintendent (Photo: NOAA)
A tiger shark lunges at a Laysan albatross. The shark's head is above water and its jaws are open; the Laysan albatross is also at the surface.
Look out! This tiger shark (niuhi in Hawaiian) is about to snag a Laysan albatross snack in Papahānaumokuākea Marine National Monument. Because of their association with shark attacks – and those impressive teeth – tiger sharks are feared by many people. But sharks like the tiger shark are incredibly important animals in ocean environments, helping keep ecosystems in balance. This Shark Week, thank a shark for keeping our ocean healthy! (Photo: Ilana Nimz/NOAA)
A sand tiger shark swims through a shipwreck.
When surveying shipwrecks throughout the Graveyard of the Atlantic, Monitor National Marine Sanctuary archaeologists often get to see sand tiger sharks like this one! Sand tiger sharks look fearsome due to their rows of protruding, ragged teeth. But in reality, they're quite docile! Shipwrecks serve as artificial reefs along the seafloor, attracting small fish and invertebrates, which are exactly what sand tiger sharks are interested in. Diving on a shipwreck? Give sand tiger sharks plenty of space and they'll do the same for you. (Photo: NOAA)
A view of mangrove trees looking up through the water.
This Shark Week, don't forget to think about shark habitat! Mangroves like these in Florida Keys National Marine Sanctuary serve as nurseries for sharks and other organisms. Mangroves are trees that grow in coastal waters, creating a dense tangle of roots throughout shallow water. These roots provide shelter to young sharks, which can prey on other small creatures that make their home in the mangroves. (Photo: David J. Ruck/NOAA)
A spiny dogfish shark turns away from the camera.
Not all sharks are big! Spiny dogfish, like this one in Cordell Bank National Marine Sanctuary, are only three or four feet long. But though they are little, they are fierce. Sharp venomous spines on front of each dorsal fin protect them from predators, and they relentlessly pursue prey like fishes, crabs, and squid. (Photo: Rick Starr/NOAA)
A black-and-white photo of a sandbar shark.
Sharks – like this sandbar shark in Flower Garden Banks National Marine Sanctuary – have several adaptations that make them excellent predators. Specialized organs called ampullae of Lorenzini help sharks sense electric fields in the water generated by other fish. Their eyes, too, are specially adapted: all shark eyes have a tapetum lucidum, a layer of mirrored crystals located behind the retina, allowing them to see in in low light conditions and up to ten times better than humans in clear water. Despite these adaptations, sandbar sharks and other sharks typically pose little threat to humans. We're more dangerous to them than they are to us! (Photo: Nick Zachar/NOAA)

A male elephant seal bellows while on a beach.
"I often think of the connectivity of the National Marine Sanctuary System. I think, for example, of elephant seals that may pass through Olympic Coast National Marine Sanctuary before making their way to Greater Farallones National Marine Sanctuary. Although we still have a lot to do for marine conservation, knowing that these sanctuaries provide habitat for all walks of marine life, from marine mammals to crustaceans, reminds me that we have done so much good already and we are only going to continue to do better." –Nissa Kriedler, Dr. Nancy Foster Scholar (Photo: Robert Schwemmer/NOAA)
Two yellow, black, and white-striped anemonefish swim above a large sea anemone.
A special mucus layer on anemonefish – like these two in National Marine Sanctuary of American Samoa – allows them to live among anemones without being stung. In return for the protection the anemone provides, the anemone gets food leftovers from the fish. Plus, the anemonefish is quite protective of its home, so it chases away anything that might be interested in chowing down on the anemone! (Photo: Greg McFall/NOAA)
A close-up of a young hawksbill sea turtle being held in a person's hand.
A turtley awesome success story! Last year, Monitor National Marine Sanctuary partnered with the Bureau of Ocean Energy Management to conduct assessments of suspected and known shipwrecks off North Carolina. On their way out to one site, researchers teamed up with NC Wildlife Resources Commission to bring along two rehabilitated sea turtles for release. This is a juvenile hawksbill named Puck, who got to go home to the ocean! (Photo: Joe Hoyt/NOAA)

A closeup view of orange and white coral polyps.
Coral: animal, vegetable, or mineral? Animal! Corals are actually made up of tiny animals called polyps. These polyps have little tentacles that they use to reach out and grab food, which they funnel in toward their stomach. Most coral polyps are nocturnal and retract inside the coral skeleton during the day. But on a night dive in places like Flower Garden Banks National Marine Sanctuary you might get to see the polyps in action! (Photo: GP Schmahl/NOAA)

A black oystercatcher comes in for a landing over the surf. Note: this is not the bird that was transported to the wildlife rehabilitation center.
"Our nonprofit partnered with Monterey Bay National Marine Sanctuary to bring 350 students to their sanctuary this year. Many of the students had never been to the ocean. To culminate their classroom lessons about marine debris, elementary students from Paso Robles, California, took a field trip to sanctuary. On the trip, the students noticed a bird in distress at the end of a pier, caught in discarded fishing line. They notified park rangers who captured the bird. The students helped transport the bird to the nearby wildlife rehabilitation center. It was the most memorable marine debris lesson ever!" – Gregory Ellis, One Cool Earth executive director (Photo: Robert Schwemmer/NOAA)
A black-and-white photo of a swimming shark in silhouette. The sun is visible through the water toward the top of the photo.
Sharks get a bad rap, but they're actually incredibly important animals in ocean environments. For one thing, sharks help remove dead or decaying debris from the ocean. This shark was photographed at Pearl and Hermes Atoll in Papahānaumokuākea Marine National Monument.

A crab rests beneath a sea anemone on the deep-sea floor of Cordell Bank National Marine Sanctuary.
"It was 3:42 am. Still pitch black outside and bleary-eyed, I scarfed down a croissant before my 4 am watch. That morning was miserable. I seldom get sea sick, but I couldn't keep my croissant down; needless to say, I was not looking forward spending the next four hours sitting in a dark shipping container trying to focus on monitors. But, when I stumbled up to the control van, I became transfixed on the screens. Dozens of beautiful bamboo corals extended out from a rocky wall like elegant fingers. A crab, perched on the wall, began to scuttle across and I quickly forgot about my seasickness and was instead mesmerized by the majesty of Cordell Bank National Marine Sanctuary. From the sea surface, you would never guess such stunning environments were just beneath the water in complete darkness! It was such a treat to see such a rare glimpse of the benthos and I was even more excited in anticipation of learning the stories of the deep sea through the chemistry of the corals in order to help protect their habitat." – Carina Fish, UC Davis/Bodega Marine Laboratory - University of California, Davis graduate student (Photo: OET/NOAA)

A person bends over a large conglomeration of fishing nets and other debris that is submerged in shallow ocean water.
Trash travels: every year, NOAA staff journey out to the Northwestern Hawaiian Islands of Papahānaumokuākea Marine National Monument to remove literal TONS of debris from these remote islands. Though the islands are largely uninhabited, ocean currents carry trash to their shores from far and wide, putting animals like albatross, Hawaiian monk seals, and green sea turtles at risk. What will you do to help keep these islands – and other ocean habitats – debris free? (Photo: Koa Matsuoka)

A white plastic bag lies crumpled on the sandy bottom of the ocean. Two anemones – one purple, one orange – are on the bag.
Trash we discard here on land can make its way into the sea, where it travels into distant ecosystems. This plastic bag, for example, was lying at the bottom of the Gulf of Mexico all the way at 5,250 feet – almost a mile down! By refusing, reducing, reusing, repurposing, and recycling, you can help reduce marine debris and negative impacts on wildlife throughout the ocean.

A person in Papahānaumokuākea Marine National Monument adds a large handful of brightly colored plastic lighters to a bin. Only the person's arms are clearly visible; they are wearing work gloves. This is a photo from the annual cleanup of remote islands within the monument.
"I worked for a wildlife charter before working for Papahānaumokuākea Marine National Monument. I witnessed plastic pollution in various forms. I witnessed two turtles bound by plastic outside of Yokohama Bay. Authorities were notified and the turtles were disentangled. I've also retrieved plastic bags from the water – removing just one bag could potentially remove at least one animal from harm's way. Like the National Marine Sanctuary System, we all rely on each other's actions for improvement and change. One person can't save the world, but we can save lives. It's up to each one of us to do our part to save these animals and oceans. As each saved life accumulates, these efforts can and will be noticeable globally." – Caroline Jackson, Papahānaumokuākea Marine National Monument administrative assistant (Photo: NOAA)

A sea lion rests at the ocean surface in a mass of kelp. It is holding its flippers and head out of the water.
While it may look like this sea lion in Cordell Bank National Marine Sanctuary is waving, it's likely actually regulating its temperature. Sea lions use their flippers to help cool down. Their flippers have less blubber than the rest of their body, so heat can escape from the flipper's surface when sea lions hold them above the water. (Photo: Dru Devlin/NOAA)

An orange and white octopus sits on a coral reef. The octopus's coloration and texture makes it well-camouflaged with the coral around it.
A day octopus – or he’e mauli in Hawaiian – sits pretty at Pearl and Hermes Atoll in Papahānaumokuākea Marine National Monument. Many cephalopods have special cells in their skin tissue called chromatophores that enable them to change color very rapidly. A part of their neuromuscular system, these cells receive signals from the environment that an octopus can use to inform color change. Octopodes of this particular species can change color almost instantly as they move over their environment, making them nearly invisible to predators! (Photo: Andrew Gray/NOAA)
A pink octopus moves away from the camera. A light orange deep-sea coral is in the foreground to the left.
A kraken of the depths? Not quite – but this octopus WAS spotted in the deep sea. Many different octopus species live in deep waters!

A Kemp's ridley sea turtle swims at the ocean surface, with its head poking above the water.
What's the smallest sea turtle in the world? The Kemp's ridley turtle! These wee sea turtles only grow to about two feet in length – from the tiny tiny hatchling size of 1.5 inches. These endangered turtles can be found throughout the Gulf of Mexico and along the U.S. Atlantic seaboard. This one was spotted off the coast of Hatteras, North Carolina, not too far from NOAA Monitor National Marine Sanctuary. If you're lucky, you might also see them in NOAA Florida Keys National Marine Sanctuary. (Photo: Peter Flood)
A hawksbill turtle rests on the reef floor. A diver swims up above it.
Did you know you can find sea turtles at every single site within the National Marine Sanctuary System, with the exception of Thunder Bay National Marine Sanctuary? It's true! Our sanctuary system protects crucial habitat and breeding grounds for many species of sea turtles. In Flower Garden Banks National Marine Sanctuary, for example, you'll find both loggerheads and hawksbills – the photo here shows a hawksbill. These relatively small turtles search in the holes and crevices of coral reefs to find sponges and other invertebrates to eat. (Photo: Emma Hickerson/NOAA)
A green sea turtle rests on a beach. In the foreground is a pile of derelict fishing nets.
One of the major threats to sea turtles is entanglement in fishing gear and other marine debris. Each year, threatened green sea turtles make their way to breeding grounds in the Northwestern Hawaiian Islands. Although these islands are largely uninhabited and are protected by Papahānaumokuākea Marine National Monument, ocean currents carry enormous quantities of trash here from around the world. More than 50 tons of debris enters monument waters each year! Here, fishing nets and other debris can entangle breeding adults and young hatchlings. You can help protect these and other sea turtles by reducing the amount of plastic you use and participating in beach and watershed cleanups. What actions will you take? (Photo: Andy Collins/NOAA)

A bright pink jellyfish extends its tentacles downward. The sea around it is dark, with small particles of marine snow illuminated.
Hot pink in the deep sea? When exploring the deep ocean, researchers will often spot creatures that appear pink or red when we shine a light on them – like this jelly in NOAA Channel Islands National Marine Sanctuary. That coloration is actually an evolutionary advantage! Red light doesn't penetrate to ocean depths, so a red fish or jelly will essentially be invisible. Read more about this ocean phenomenon.

Your national marine sanctuaries protect all sorts of ecosystems, including coral reefs – like this gorgeous one at Rose Atoll in NOAA National Marine Sanctuary of American Samoa. Coral reefs support enormous biodiversity – you'll find more species per unit in these reefs than any other ecosystem on Earth. Plus, they harbor lush fisheries, protect our coastlines from storm surge and erosion, and support to local economies through tourism. This World Environment Day, thank a coral reef!

A close-up on a Hawaiian monk seal's face. Its eyes are closed and it is nestled under greenery in a way that makes the plants look like a flower crown.
This Hawaiian monk seal made its own flower crown for a seal-fie! These endangered seals haul out on beaches throughout Papahānaumokuākea Marine National Monument and NOAA Hawaiian Islands Humpback Whale National Marine Sanctuary to rest and look generally fabulous. Make sure to give them plenty of space so they can enjoy their time on the beach!

"There is incredible diversity in each sanctuary on our planet that we work to protect, it's absolutely inspiring. People of all ages, from all different backgrounds, come together to fight for something so vitally important and beautiful. Once you explore it, you're hooked. I try to be a member on as many conservation boards as I can and educate myself and others on the future of our oceans and waters. For me, it's always a very rewarding experience to bring people out to NOAA Channel Islands National Marine Sanctuary, to really SHOW them rather than tell them. It's easy to become inspired in a sanctuary as beautiful as in the Channel Islands." – Michael Cohen, Channel Islands Adventure Company founder (Photo: Cindy Shaw)
An adult northern fulmar taking off from the surface of the ocean. The bird is facing away from the camera.
How did the fulmar get its name? This seabird's name comes from Old Norse for "foul gull." To defend themselves and their nest site, fulmar chicks will projectile vomit a foul-smelling stomach oil. How's that for a tern-off? (Photo: Peter Pearsall/U.S. Fish and Wildlife Service)
A view through a school of Atlantic spadefish. The fish are silver with black stripes. The light of the sun is visible on the right-hand side of the photo through the water column.
Gray's Reef National Marine Sanctuary has fish in spades – spadefish, that is! Divers visiting this sanctuary off the coast of Georgia are often surrounded by schooling fish like these. Learn about diving in your sanctuaries.(Photo: Greg McFall/NOAA)

"Hey, I'm flying here!" This black-legged kittiwake and Cory's shearwater got a little close while flying in Stellwagen Bank National Marine Sanctuary. Fowl play, perhaps? (Photo: Peter Flood)
A red and brown hermit crab occupying a snail shell.
Feeling a little crabby? You're in good company! Hermit crabs can be found in many of your national marine sanctuaries, including NOAA Hawaiian Islands Humpback Whale National Marine Sanctuary, like this one. These wee crustaceans use empty shells to protect themselves. As they get bigger, they move into larger, more accommodating shells. (Photo: NOAA)

A diver carrying a camera swims above a sunken aircraft wing.
Today, for Memorial Day, we honor the many men and women who gave their lives in service to our nation. In addition to protecting important ecosystems and habitats, your National Marine Sanctuary System also protects maritime heritage resources that tell the story of our maritime nation. Papahānaumokuākea Marine National Monument, for example, protects the waters around Midway Atoll, which are the resting place for at least 31 sunken aircraft that are considered war graves. The Battle of Midway was one of the most decisive U.S. victories of WWII and is referred to as the turning point of the war in the Pacific. Here, a diver documents the wing section of a F4U Corsair. Find out more about a recent expedition to explore these aircraft and honor the legacy of the brave men who helped to turn the tide in the Pacific. (Photo: Tane Casserley/NOAA)
Members of the Chumash community paddle a traditional tomol, or plank canoe. The sun is rising in the background and the paddlers are in silhouette.
"In my capacity as a caretaker of NOAA Channel Islands National Marine Sanctuary, I am always humbled by the knowledge that the first people of these islands and waters, the Chumash, have known for thousands of years about the life-sustaining, culturally-defining and sacred nature of this place. As I go about our work, I strive to learn from and honor these indigenous values and the Chumash people of our community. Through this native connection and wisdom, our sanctuary mission is even more profound." – Mike Murray, Channel Islands National Marine Sanctuary deputy superintendent for programs (Photo: Robert Schwemmer/NOAA)

A black-footed albatross flies above the ocean. The bird's plumage is brown, and its wings stretch from the top of the photo to the bottom.
Cordell Bank National Marine Sanctuary was established in 1989 to protect the lush ecosystems on and around Cordell Bank, a rocky feature off the coast of California. Marine mammals and migratory seabirds – like black-footed albatrosses, pictured here – travel here from all over the Pacific Ocean to feed! (Photo: Douglas Croft Images)
A loggerhead sea turtle swims near the sea floor. Its shell has numerous barnacles encrusted on it. In the background, fish swim over a ledge covered in invertebrates.
Sea turtles are found in almost all of your national marine sanctuaries. Loggerhead turtles like this one often frequent NOAA Gray's Reef National Marine Sanctuary off the coast of Georgia. Here, they can be spotted resting among the natural reef ledges and basking at the ocean's surface. (Photo: Peter Auster/NOAA/UConn/Mystic Aquarium)
A California sheephead swims through a sunlit kelp forest.
Kelp forests, like those in Channel Islands National Marine Sanctuary and other West Coast sanctuaries, are home to enormous biodiversity. Kelp forests provide food and shelter for many marine animals. Here, you'll find juvenile fish hiding from predators, sea stars hunting sea urchins, sea otters searching for invertebrate snacks, and more. (Photo: Robert Schwemmer/NOAA)
A close-up view of a starburst anemone.
Explore the tidepools of Greater Farallones National Marine Sanctuary and you're likely to see anemones like this starburst anemone! Though anemones look rather like flowers, they're actually animals. Their "petals" are stinging tentacles that they use to gather food like small fish and crabs toward their mouth. (Photo: Sara Heintzelman/NOAA)
Fish swim above the wreck of the German U-boat U-85.
"Working for NOAA Monitor National Marine Sanctuary opened my world to a new appreciation for cultural resources and our nation’s maritime heritage. I love telling people the wonderful stories of the Civil War ironclad, USS Monitor, and its brave crew, the Monitor Boys. Our sanctuary also researches the rich maritime history that exists all around Monitor, up and down the North Carolina coast, including World War I and World War II shipwrecks. With each shipwreck, I eagerly dive in to learn its stories and share them with students, teachers, and the public!" – Shannon Ricles, Monitor National Marine Sanctuary education and outreach coordinator (Photo: Steve Sellers/NOAA)

A Hawaiian monk seal scoots on the beach toward the ocean. A small transmitter is attached to its back. Birds take flight in the background.
The National Marine Sanctuary System provides important refuge for many endangered species, from leatherback sea turtles to Hawaiian monk seals like this one. Though Hawaiian monk seals are one of the most endangered marine mammals on the planet, through protection efforts by NOAA and our partners, their numbers have been increasing over the past several years. Here, a rehabilitated monk seal heads home to the ocean in Papahānaumokuākea Marine National Monument. The transmitter on its back will allow researchers to track its movements and learn more about Hawaiian monk seal populations. If you see a Hawaiian monk seal when you're in Hawai‘i, you can help protect it by giving it plenty of space so it can rest or hunt. You can also help by reporting your sightings to the island's local Marine Mammal Response Coordinator. The more we know about where these seals are, the better we can care for them! (Photo: NOAA)
A tan-colored octopus blends into sand on the seafloor.
If I stay very still, you can't see me! Octopuses like this one in Gray's Reef National Marine Sanctuary are masters of disguise. Special pigmented cells called chromatophores allow them to change color and texture in the flash of an eye, helping them hide from predators and prey alike! (Photo: Alicia Reigel/LSU)
A side view of a California brown sea hare grazing on algae. The sea hare has two sensory organs on top of its head that look like rabbit ears.
Did you know that rabbits live in the ocean? Well, not exactly – but you can find sea hares! California brown sea hares like this one in NOAA Channel Islands National Marine Sanctuary are actually large sea slugs. They get their name from the sensory organs on their heads that look rather like rabbit ears. Also like rabbits, they are grazers, though they far prefer algae to anything terrestrial. Have you spotted sea hares while tidepooling or diving in your California sanctuaries? (Photo: Dr. Tony Knight)
A close view of a nudibranch, a shell-less mollusk. The nudibranch is dark red, with orange branching gills.
Bad hair day? Not quite! This is Dendronotus iris, a kind of nudibranch. Those "hairs" you see are actually branching gills, which can be tipped with white, orange, yellow, or purple. This nudibranch prowls the rocky reefs of Monterey Bay National Marine Sanctuary for anemones to chow down on. (Photo: Chad King/NOAA)
A black and white North Atlantic right whale breaches out of the water. Its belly and flippers are visible.
Now that's a whale of a breach! This North Atlantic right whale was photographed breaching in the waters near Stellwagen Bank National Marine Sanctuary. North Atlantic right whales are one of the most endangered marine mammals in the world, with only about 450 remaining. After years of being hunted for their blubber and baleen, today they are at risk of entanglement and ship strikes. There is some good news: Stellwagen Bank is working closely with partners like NOAA Fisheries to protect these whales and reduce threats. (Photo: Peter Flood)

"As a biology student and someone who is passionate about ocean conservation, I learn more and more of the negative trends in which our environment is heading. Sanctuaries give me hope that not all will be lost. Sanctuary waters are full of healthy marine life and incredibly beautiful ecosystems. Seeing how vibrant our ocean can be inspires me to be a better guest to this planet." – Savanna Mahn, constituent and legislative affairs volunteer intern, Office of National Marine Sanctuaries (Photo: Robert Schwemmer/NOAA)
A white and brown Laysan albatross stands over a small fluffy chick. The adult is looking down at the chick.
This weekend we celebrate both World Migratory Bird Day and Mother's Day – and what better way than with Wisdom the Laysan albatross? At about 67 years old, Wisdom is the oldest known wild bird in the world, and is a mother many times over! Here she is with her 2017 chick on Midway Atoll in Papahānaumokuākea Marine National Monument. Every year, Laysan albatrosses and numerous other bird species migrate from their feeding grounds to the Northwestern Hawaiian Islands to breed and raise their chicks. Protecting these places helps ensure the survival of new generations! (Photo: Naomi Blinick/U.S. Fish and Wildlife Service)
A brown duck walks on wet sand, leaning forward with its bill near the sand.
This little cutie is none other than the Laysan duck. These ducks are considered the rarest native waterfowl in the United States: while once they were found throughout the Hawaiian Islands, today they only reside in the Northwestern Hawaiian Islands. There, they're protected by Papahānaumokuākea Marine National Monument. In recent years, Pacific Islands: U.S. Fish and Wildlife Service has relocated some Laysan ducks from Laysan Island to Midway Atoll and Kure Atoll, in order to increase their chance of survival!

A snowy egret stands in shallow water. The bird is white, with a long neck, yellow and black bill, and black legs.
Whether you're a birdwatching beginner or an avian expert, national marine sanctuaries are a bird enthusiast's paradise! Snowy egrets are just one of the hundreds of species of bird to visit Florida Keys National Marine Sanctuary. Keep a sharp eye on the shallows and you might spot these beautiful birds using their brilliant yellow feet to stir up prey! (Photo: Matt McIntosh/NOAA)
A black oystercatcher stands on a rock in front of breaking waves. The bird is black, with an yellow eye, red-orange bill, and pinkish legs.
Seabirds aren't the only birds that rely on national marine sanctuaries. For shorebirds like this black oystercatcher in Monterey Bay National Marine Sanctuary, sanctuaries are home. Black oystercatchers patrol the intertidal zone, looking for mussels and other shellfish. They find open mussels, jab that long bill in, and extract the contents for a hearty seafood meal. (Photo: Robert Schwemmer/NOAA)

An elephant seal resting in the surf.
"One day, there was an injured elephant seal on the public beach outside my office. It's a popular beach with people and dog-walkers. There was also a group of three families from the US and France at a family reunion. I asked the kids if they wanted to help me make a driftwood fence around the injured seal to keep dogs and people away. The kids, four to 12 years old, quickly gathered bundles of driftwood and made a stick fence around the seal giving it about 20 feet on all sides. The parents wanted to leave to see the sunset, but the kids would not go until their project was done. They were so proud of their accomplishment, I got a huge group hug and lots of group pictures before they left. In my work, this is what I'm most proud of: connecting kids to the ocean, making them feel important through stewardship activities, and empowering them to take action." – Carolyn Skinder, Monterey Bay National Marine Sanctuary southern region program coordinator (Photo: Robert Schwemmer/NOAA)
A close-up on a red-orange giant Pacific octopus resting on the sea floor.
Excuse me, this space is already octopied! This giant Pacific octopus was spotted hanging out in NOAA Olympic Coast National Marine Sanctuary.

If you live inland, it may seem like you're not very connected to the ocean – but through rivers and watersheds, you are! Waterways like these also connect fish habitats. Salmon like these coho salmon spend much of their lives at sea in Olympic Coast National Marine Sanctuary, then make their way up rivers in Olympic National Park to spawn. By protecting both ocean and river ecosystems, we help ensure species like these salmon can thrive! (Photo: Adam Baus)

Three Hawaiian monk seals play in shallow water.
Cuddle pile! These are Hawaiian monk seals, or ilio-holo-i-ka-uaua in Hawaiian. Though they are one of the most endangered marine mammals in the world, there is some good news -- populations have increased by three percent annually for the past three years thanks to work by NOAA and our partners. Today, about 1,100 live in Papahānaumokuākea Marine National Monument, while an additional 300 reside in the Main Hawaiian Islands. If you see a Hawaiian monk seal on the beach or in the ocean, please let us know so we can better understand and track this endangered species! Get more info on how to report sightings. (Photo: NOAA)
Three divers holding photographic equipment swim above the greenish hull of a shipwreck. Schools of fish swim in the background.
Photographing history: divers from Monitor National Marine Sanctuary and East Carolina University photograph the German U-boat U-352. This U-boat sank on May 9, 1942 and was the first U-boat sunk by the U.S. Coast Guard off the U.S. East Coast during World War II. Today, U-352 is one of the most frequently-dived U-boats in the Graveyard of the Atlantic. It rests in 115 feet of water and is covered in coralline algae, sea anemones, and corals. Red barbier baitfish and amberjack are so common that it can be difficult to take a clear photograph of the wreck! (Photo: NOAA)
A deep-sea fish rests above the sea floor. Two small parasitic isopods are attached to its fins.
Happy Bat Appreciation Day! There are lots of bats beneath the waves, like BAThypterois viridensis, a type of tripod fish. Tripod fishes rest on the seafloor on the tips of elongated rays of their pelvic and lower caudal fins. They use the elongated rays of their pectoral fins as sensory “antennae” that project out and forward as the fish sits facing into the current.

A common dolphin rises from the surface of the ocean. In front of it, a tail of another dolphin is above the surface.
Happy National Dolphin Day! Common dolphins like these are often spotted in Stellwagen Bank National Marine Sanctuary. Common dolphins are eager bow-riders, and sometimes can be spotted in groups of hundreds or thousands! In the sanctuary, they prey on squid and other small schooling fish. (Photo: Peter Flood)
white sponges cling to the side of a muddy slope. A brittle star clings to one of them and other invertebrates grow above the sponges. Two laser dots calibrated to 10cm apart show the size of the sponges.
Discovery in the deep! This beautiful deep-sea sponge is actually a new species. In 2017, scientists on board the E/V Nautilus used a remotely operated vehicle to explore never-before-visited areas of Cordell Bank National Marine Sanctuary. Among the creatures they saw were two new species of sponge! The sponge in the foreground here is one of them, and is a kind of Farrea sponge. (Photo: NOAA/OET)
An aerial view of a mother humpback whale and her calf swimming through bright blue ocean water. The calf is close to the mother's side.
The cuteness here is over-whale-ming! Each winter, thousands of humpback whales visit the warm waters of Hawaiian Islands Humpback Whale National Marine Sanctuary to mate, give birth, and care for their newborns. Mothers and calves like this pair can often be seen swimming or resting at the surface. While adult humpback whales can hold their breath for 10 to 15 minutes, calves must rise to the surface every three to five minutes to breathe. (Photo: J. Moore/NOAA, under MMHSRP permit #20311)
A female snorkeler swims over the flattened remains of a wooden shipwreck. The water is blue while the shipwreck appears greenish-yellow.
You don't have to be a diver to explore the shipwrecks of Thunder Bay National Marine Sanctuary! Many of the historic wrecks in this Great Lakes sanctuary are shallow enough to explore with a snorkel or a kayak. This is the wreck of the wooden schooner Portland, which sank more than a century ago after running aground. (Photo: David J. Ruck/NOAA)

Heroes in training: last month, Monterey Bay National Marine Sanctuary staff and partners were trained to safely disentangle whales. One skill they practiced was how to attach a telemetry buoy to gear entangling a whale, which allows rescuers to track the whale's movements. Knowing where the whale is helps buy more time for experts to attempt to set it free. Disentangling whales is extremely dangerous work and requires expertise and training. Responders never get into the water with a whale, and nor should you! If you see an entangled whale, please alert your local marine mammal stranding network: https://www.fisheries.noaa.gov/report.

A large mola mola swims above the sea floor. Smaller fish swim beneath it.
Holy mola! Don't be fooled, this isn't a baby whale – it's a mola mola! Also known as ocean sunfish, mola mola are the largest bony fish in the ocean. Despite their huge size (they can weigh more than 2,000 pounds!) these fish chow down on tiny prey like jellyfish. This mola mola was spotted in NOAA Gray's Reef National Marine Sanctuary.

Two divers, surrounded by pink fish, swim above a vibrant rocky reef. The reef is covered in bright pink strawberry anemones and other colorful invertebrates.
"I am inspired by the communities of people that led the way to preserve the incredible treasures that the National Marine Sanctuary System protects. Everyday people like you and me stepped up to participate in the federal processes to help stewards take care of these special ocean and Great Lakes places. That level of collaboration inspires me. Now, we need to find ways to connect all people to the ocean so they form their own personal love and care for it. Its easy for me, growing up and living so close to a shoreline my entire life, but I often think about those that live out of reach, or the means to get there are not possible, or those that are states away. How can we inspire an ethic to conserve our ocean to those that can't experience its awe itself?" – Jennifer Stock, Cordell Bank National Marine Sanctuary education & outreach coordinator
An orange sea star clings upside down within a rock crevice. The top rock is covered in limpets and other invertebrates; the bottom rock is coated in algae.
Hold tight, little sea star! Look closely and you can see this sea star's tube feet, which it uses to cling to this tidepool in Greater Farallones National Marine Sanctuary. A sea star's tube feet use hydraulic pressure to move, and then the tube foot likely uses a glue-like substance to stick to the rock. Sea stars aren't the only ocean animals with tube feet – their cousins sea urchins, sand dollars, and sea cucumbers also have them. (Photo: Sara Heintzelman/NOAA)
A reddish octopus sits against a reef on the sea floor on top of a few shells. A fish swims above
Apr. 6, 2018: Look closely and you'll see this octopus in Gray's Reef National Marine Sanctuary is mid-snack on some shellfish! But how do octopuses eat, anyway? An octopus's mouth is on its underside, and contains a hard beak. The beak is made of chitin, a material similar to what's in your fingernails, and helps the octopus chow down on tough food!

a bobcat stretches out between two small rocks in the midst of a river in golden light
Apr. 5, 2018: Stretch it out! On the Olympic Peninsula, land and sea are closely connected. Olympic Coast National Marine Sanctuary works closely with Olympic National Park to protect the animals that depend on these watersheds. Here, a bobcat hunts for salmon. Salmon that swim up rivers to spawn in the park live much of their lives in sanctuary waters offshore: seven species of Pacific salmon can be found along the outer coast of Washington.

North Atlantic right whale breaching
Apr. 4, 2018: Celebrate Whale Wednesday with this amazing view of a North Atlantic right whale breaching! With only about 450 individuals remaining, the North Atlantic right whale is one of the most endangered marine mammals in the world. Each year, many of them travel to Stellwagen Bank National Marine Sanctuary off the coast of Massachusetts to feed. The sanctuary has been collaborating with partners to find innovative ways to protect these whales from entanglement and ship strikes. (Photo: Peter Flood)
Cockerell's dorid
Apr. 3, 2018: Is this Cockerell's dorid wearing orange in decoration? Perhaps, but these q-tip-like appendages serve another function. They're called cerata, and function sort of like external gills, aiding the dorid in respiration! (Photo: Steve Lonhart/NOAA, taken in Monterey Bay National Marine Sanctuary)
orange colored Crinoid
Apr. 2, 2018: Blast from the past: Crinoids like this one are living fossils. They've been in our ocean for almost 500 million years! Don't let their plant-like appearance fool you: crinoids are invertebrates, and are relatives of sea stars and sea urchins. This one was photographed in Flower Garden Banks National Marine Sanctuary.

octopus blending into its surrounding
Mar. 30, 2018: Ocean magic eye puzzle: look carefully and you'll see an octopus! Octopuses, as well as many of their squid and cuttlefish cousins, are masters of camouflage. Special pigmented cells in their skin called chromatophores enable them to change color rapidly. Part of the octopus's neuromuscular system, these cells receive signals from the environment, helping the octopus hide from predators and prey! Despite its excellent disguise, this octopus was spotted in Gray's Reef National Marine Sanctuary. (Photo: Greg McFall/NOAA)

white-spotted rose anemone clings to and attempts to ingest a moon jelly
Mar. 27, 2018: Talk about a big bite! Here, a white-spotted rose anemone clings to and attempts to ingest a moon jelly in Monterey Bay National Marine Sanctuary. Although the jelly is twice the size of the anemone, most of the jelly is water, so it's not an impossibly large meal. While moon jellies are usually open ocean species, sometimes oceanographic conditions bring them closer to shore – and into the mouths of creatures like this anemone. (Photo: Steve Lonhart/NOAA)
elephant seals resting on the beach
Mar. 26, 2018: Someone's got a case of the Mondays! Northern elephant seals like these haul out each year along the California coast, including in Greater Farallones National Marine Sanctuary. On shore, they rest, mate, and raise their young. Though elephant seals look goofy, it's always important to remember that these are wild animals and give them plenty of space! Learn how to safely watch wildlife along the coast. (Photo: Sara Heintzelman/NOAA)
many different types of fish swimming together
Mar. 25, 2018: "Being a dive master has opened up so many incredible doors for me. One of the most rewarding parts of getting to lead people around is when they notice garbage or fishing line on the reef and help to remove it. I think the reason the sanctuaries are so successful is that it allows people to physically see what is being protected by the law. Because of this firsthand experience anyone can have, they learn to appreciate the marine life and want to help protect it too! " - Natalie Nites, NOAA Florida Keys National Marine Sanctuary Team OCEAN volunteer. (Photo: Daryl Duda)

Scrawled filefish swimming near a reef
Mar. 11, 2018: "I make sure that when I am boating that nothing goes into the water, I try to recycle everything I can, and I don't eat seafood unless it is invasive lionfish. I also participate in as many coastal cleanups to help to remove all of the garbage along our shorelines and I try to encourage others to do the same. We have a long ways to go in ocean conservation, but national marine sanctuaries, along with national parks, monuments, and wildlife refuges, afford us the best opportunity to help leverage limited resources to address coastal and marine conservation." – Mark Chiappone, research associate at Nova Southeastern University and assistant professor at Miami Dade College (Photo: Scrawled filefish in NOAA Florida Keys National Marine Sanctuary.

Mar. 3, 2018: March is Dolphin Awareness Month, and here at Sanctuaries, we love our dolphins! Dr. Nancy Foster Scholar Alexandra Avila photographed these Hawaiian spinner dolphins in Hawaiian Islands Humpback Whale National Marine Sanctuary. Spinner dolphins are incredibly gregarious, sometimes gathering in groups of several hundred or more! These dolphins feed at night and return to coastal waters to rest and socialize. Because they rest during the day, it's important to give them lots of space -- would you like someone trying to hang out with you when you're trying to get some shut-eye? (Photo: Alexandra Avila)
shipwreck on the beach covered invasive species
Mar. 2, 2018: Where do invasive species come from? In some cases, nonnative species can hitch a ride to new places on ships or via marine debris, like this derelict vessel near Olympic Coast National Marine Sanctuary. Though species can also travel from one place to another on organic matter, plastic and other manmade materials don't degrade as quickly and are more likely to cross large distances. You can help reduce the spread of invasive species by reducing marine debris: always dispose of your waste properly and join beach cleanups in your area whenever you can! (Photo: NOAA)
women holding up a loinfish she caught
Mar. 1, 2018: Fishing for a cause: Each year, Flower Garden Banks National Marine Sanctuary holds the "Lionfish Invitational," a lionfish research and removal effort in the sanctuary. In recent decades, Indo-Pacific lionfish have invaded the reefs of the Flower Garden Banks and other sanctuaries, threatening fish populations and reef biodiversity. In an effort to limit the effects of the lionfish, divers and researchers spend several days removing them from the reef. Scientists also conduct surveys to determine what species, quantities, and sizes of fish are present. Here, participant Rachel Bowman holds up a lionfish after a dive. (Photo: Andy Lowe)
a shrimp crawls over the invasive Watersipora subtorquata
Feb. 28, 2018: Watersipora Wednesday! Here, a shrimp crawls over the invasive Watersipora subtorquata in Monterey Bay National Marine Sanctuary. Watersipora is an invasive genus of bryozoan -- or aquatic filter-feeding invertebrate -- that has taken up residence in and around the sanctuary. Though there's still much to learn about how these organisms grow and thrive, Watersipora are thought to have been introduced to the California coast by hitching a ride on ships and boats traveling along the coastline. Once settled in a new environment, Watersipora can have damaging effects on native invertebrate species, smothering them and outcompeting them for space. But researchers at Monterey Bay National Marine Sanctuary have been working hard to understand how these organisms grow and thrive, and what ecological consequences we can anticipate from their spread.

diver holding a captured lionfish
Feb. 27, 2018: With voracious appetites and no natural predators in the Atlantic, invasive lionfish are seriously threatening coral reef biodiversity and health in several national marine sanctuaries. There is good news, though: research led by scientists from REEF Reef Environmental Education Foundation shows that volunteers can help defend local marine habitats! The data show that lionfish derbies in areas including Florida Keys National Marine Sanctuary can reduce lionfish numbers by 52 percent across an area of nearly 75 square miles.

Pacific white-sided dolphins jumping out of the water
Feb. 15, 2018: We're continuing to leap through Whale Week with these Pacific white-sided dolphins! For fifteen years, Cordell Bank National Marine Sanctuary, Greater Farallones National Marine Sanctuary, and Point Blue Conservation Science have been collaborating to understand how whales, dolphins, and other marine creatures use sanctuary habitats. Data from the ACCESS Partnership have been used to help ensure the safety of these wonderful animals. For example, sanctuary managers use the data to reduce the overlap of whales and ships transiting to and from the ports of San Francisco Bay. (Photo: NOAA/Point Blue/ACCESS)
Humpback Whale entangled in marine debris
Feb. 14, 2018: One of the biggest risks to humpback whales and other whales is entanglement by fishing gear and other debris. Hawaiian Islands Humpback Whale National Marine Sanctuary leads the Hawaiian Islands Disentanglement Network, a community-based network that works to locate entangled whales and free them. In March 2017, the team removed more than 500 feet of electrical cable from this whale! You can help protect whales like this one by disposing of waste properly and participating in beach cleanups near you. Less trash in the ocean means less risks to these magnificent whales! (Photo: Ed Lyman/NOAA, under MMHSRP Permit #18786)
North Atlantic right whale feeding near Atlantic white-sided dolphins
Feb. 13, 2018: The North Atlantic right whale is one of the most critically endangered populations of large whales in the world -- there are likely only about 450 left in the wild. Each year, right whales travel to Stellwagen Bank National Marine Sanctuary to feed, and give birth to young in the warm waters near Gray's Reef National Marine Sanctuary. To protect these whales, we're working closely with NOAA Fisheries and other partners to reduce human impacts, like collisions with vessels and entanglements in fishing gear. You can help protect right whales, too, by supporting your regional stranding network and by working to reduce marine debris! This right whale is known as Scoop. He's an adult male who was first sighted in 1982 and has fathered at least 3 calves. Here, he's feeding near Atlantic white-sided dolphins -- images like these give a sense of just how big whales like Scoop are! (Photo: Allison Henry/NOAA, under MMPA Permit #17335)
breaching humpback whale
Feb. 12, 2018: Whale what do you know? It's Whale Week! All week long, we'll be celebrating these gentle giants that are found throughout our national marine sanctuaries. This magnificent breaching humpback whale is Salt, the "grand dame" of Stellwagen Bank National Marine Sanctuary She was first spotted in Massachusetts Bay in the 1970s, and has been seen in the sanctuary just about every year since then. She has had 14 calves and many grandchildren, and at least one great-grandcalf! Salt was one of the first northern humpback whales to be recognized at Silver Bank off the coast of the Dominican Republic, providing proof of the humpback whale migratory route in the North Atlantic -- which in turn has helped us better protect humpback whale populations through "sister sanctuary" relationships.

Jan. 24, 2018: Ulua you looking at? Ulua is the Hawaiian name for the giant trevally, one of the top predators of Papahānaumokuākea Marine National Monument in the Northwestern Hawaiian Islands. Ulua are now relatively rare in the main Hawaiian Islands due to human impacts like fishing, but they are often seen in the monument. Ulua are quite large: they can grow to weigh more than 100 pounds! (Photo: John Burns/NOAA)
fish swimming around a coral reef
Jan. 23, 2018: Fagatele Bay in National Marine Sanctuary of American Samoa is a coral-lover's dream. This small bay is only about a quarter-square-mile in area, but is home to nearly 170 species of coral! (Photo: David J. Ruck/NOAA)
humpback whale feeding at the surface of the water
Jan 19, 2018: Open wide! Humpback whales like this one in Stellwagen Bank National Marine Sanctuary are filter-feeders, chowing down on small schooling fish and krill. Plates of baleen – the hairlike material you can see on the roof of this humpback whale's mouth – help them strain out tiny prey from huge gulps of seawater. A humpback whale can have between 300 and 400 baleen plates on each side of its mouth! (Photo: Carolyn O'Connor)
close up of a sea fan
Jan. 18, 2018: This "arm" reaching for you belongs to none other than a red gorgonian, Lophogorgia chilensis. Also known as sea fans and sea whips, gorgonians are closely related to coral. Like corals, gorgonians are colonies of individual organisms. Those white, flower-like appendages are actually polyps, reaching out to grab plankton and other prey. This beautiful gorgonian was photographed in NOAA Channel Islands National Marine Sanctuary. (Photo: Evan Barba)
spotted moray eel
Jan. 17, 2018: What??? It's Flower Garden Banks National Marine Sanctuary's anniversary?? This spotted moray eel may be shocked, but it's true -- the sanctuary is 26 years old today! This vibrant sanctuary is located in the Gulf of Mexico and protects some of the healthiest coral reefs in the world. Learn more at flowergarden.noaa.gov. (Photo: Steve Miller)
top: seabird swimming, bottom: crab
Jan. 16, 2018: Happy 37th anniversary to Gray's Reef National Marine Sanctuary and Greater Farallones National Marine Sanctuary! Though these two sanctuaries share a birthday, they're quite different. Off the coast of California, the misty Greater Farallones provides breeding and feeding grounds for whales, sharks, seabirds, and more. Georgia's Gray's Reef, on the other hand, protects a live-bottom reef home to more than 200 species of fish, as well as invertebrates like this little crab. Happy anniversary to these two sanctuaries, and many thanks to their staff and volunteers for protecting our ocean's amazing places! (Top photo: Patrick Sysiong; bottom photo: Greg McFall/NOAA)
lobate comb jelly
Jan. 15, 2018: What on Earth is this mysterious blob? A lobate comb jelly, of course! Comb jellies, or ctenophores, move around by beating comb-like rows of cilia. This one was spotted in Monterey Bay National Marine Sanctuary. (Photo: Chad King/NOAA)
wreck of D.M. Wilson
Jan. 14, 2018: Ever wish you could hop into a time machine? Diving in Thunder Bay National Marine Sanctuary, you can get pretty close by exploring some of the best-preserved shipwrecks in the world. This is the wreck of D.M. Wilson, a wooden bulk freighter that sank in 1894 after springing a leak. Much of Wilson's hull remains intact today! (Photo: David J. Ruck/NOAA)
green sea turtle
Jan. 13, 2018: It's a honu world! In Hawaiian, green sea turtles are known as honu. These turtles can frequently be spotted in Hawaiian Islands Humpback Whale National Marine Sanctuary, where they chow down on algae and seagrasses. (Photo: Claire Fackler/NOAA)
pink hydrocoral
Jan. 12, 2018: Does this pink look a little tropical to you? Don't be fooled! This pink hydrocoral was actually photographed in the cold, deep waters of Cordell Bank National Marine Sanctuary, off the coast of Northern California. The rocky habitat of Cordell Bank rises from the seafloor of the continental shelf, and hosts all sorts of technicolor creatures! (Photo: NOAA)
Sunset at Rialto Beach
Jan. 11, 2018: Need a moment of relaxation? Take a deep breath and imagine the sound of waves splashing into shore on this rocky Pacific Northwest beach. Sunsets at Rialto Beach in NOAA Olympic Coast National Marine Sanctuary and Olympic National Park are spectacular. What's your favorite sanctuary to catch the sunset from? (Photo: Adam Baus)
Venus flytrap anemone
Jan. 10, 2018: Watch out – this Venus flytrap anemone stings! Like the plant from which they get their name, Venus flytrap anemones trap unwitting prey. The anemone's tentacles contain stinging cells that inject venom and can close to keep prey from escaping. This beautiful anemone was spotted in the deep waters of National Marine Sanctuary of American Samoa by researchers aboard the NOAA Ship Okeanos Explorer. The anemone itself is perched on top of a dead Iridogorgia coral, perhaps to better access the current and passing prey. (Photo: NOAA Office of Ocean Exploration and Research, 2017 American Samoa)
a pair of manta rays swimming
Jan 9, 2018: These two were manta be together! These manta rays were spotted at Pearl and Hermes Atoll in Papahānaumokuākea Marine National Monument. Known as hāhālua in Hawaiian, manta rays can weigh up to 3,000 pounds and have wingspans of 20 feet across. Despite their size, they have tiny prey: these enormous fish feed on plankton.

Sand tiger shark swims past a diver
Jan. 8, 2018: Close encounters of the shark kind! Last year, Monitor National Marine Sanctuary partnered with the Bureau of Ocean Energy Management to assess shipwreck sites off the coast of North Carolina. Here, East Carolina University diving safety officer Jason Nunn encounters a sand tiger shark amidst the wreck of Raritan. Sand tiger sharks are often found at shipwreck sites in these areas. Though their scraggly teeth give them a fearsome appearance, they're actually quite docile! (Photo: John McCord/CSI)
coral reef with fish swimming around
Jan. 7, 2018: "The most inspiring feature of the National Marine Sanctuary System is its ability to capture people from a young age. In 13 years of teaching marine science I've seen it happen right in front of my eyes. Year after year, young adults who visited NOAA Florida Keys National Marine Sanctuary through the MarineLab program either apply for jobs with us or come to tell me about how being in this environment has inspired them to pursue a career to further understand and protect it. My children may not grow up to pursue a career in marine science (or they might), but I hope that no matter their career choice, they have a strong enough knowledge of our ocean to be able to make good choices for its future. I hope this for everyone." – Jessica Dockery, director of education at MarineLab Environmental Education Center/Marine Resources Development Foundation (Photo: Daryl Duda)
elephant seal hanging out on the shore
Jan. 6, 2018: This elephant seal was spotted hanging out on the shores of Monterey Bay National Marine Sanctuary. Each year, elephant seals haul out on these beaches to molt, give birth, and mate. These elephant seals need their rest, and approaching them can be dangerous – always give them plenty of space! If you're looking to get a seal photo like this one, a zoom lens is key.

Jan. 5, 2018: New year, new life – Wisdom, the oldest known bird in the world, has laid another egg! A Laysan albatross, Wisdom is approximately 67 years old. Each year, she flies to Papahānaumokuākea Marine National Monument to meet up with her mate, Akeakamai. Since 2006, Wisdom has successfully raised and fledged at least nine chicks. Here, Akeakamai tends to their egg while Wisdom forages offshore for food. (Photo: Jodi Spross/U.S. Fish and Wildlife Service) USFWS Pacific Region
sanctuary responders on boat removing marine debris from a whale
Jan. 4, 2018: A Christmas miracle! On December 25th, these intrepid responders from Hawaiian Islands Humpback Whale National Marine Sanctuary freed an entangled whale off Maui. The whale had been trailing some 400 feet of heavy gauge line from its mouth, but working with partners, sanctuary responders were able to remove and recover all the gear. Many thanks to these ocean heroes! If you spot an entangled whale, please don't try to disentangle it yourself – this can be dangerous for both you and the whale. Instead, call your local marine mammal stranding coordinator hotline. (Photo: J. Moore/NOAA, under NOAA MMHSRP permit #18785-02)
