When you look at our planet from space, one thing is abundantly clear: Earth Is Blue. Our planet is an ocean planet, and whether you live near the coast or a thousand miles from it, the ocean is part of your life. From providing the food we eat to determining our weather, the ocean matters to each of us -- and the National Marine Sanctuary System protects this vital resource.
With that in mind, the photos and videos of Earth Is Blue bring these ocean treasures directly to smartphones and computers all over the world, where they can serve as a tangible reminder that 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.

Despite their colorful and flowery appearance, sea anemones – like this one in 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)
