Pacific sea nettles are a type of jellyfish that frequent the waters of your West Coast national marine sanctuaries.

Their reddish-brown bell can grow up to three feet wide, with tentacles reaching 15 feet or more!

This species is the most abundant of the large jellies found in the California current.

Sea nettles are important predators, drifting with the currents capturing small fish and plankton in their tentacles.

Like all jellies, sea nettle tentacles are packed with tiny barbed stingers that inject a paralyzing toxin into their prey.

When currents carry sea nettles into kelp forests, they become prey for a variety of other species, including sea turtles, fish, crabs, and sea stars.

In recent decades, large “blooms” of sea nettles, and other jellies, have increased in frequency and size along the West Coast.

While blooms can benefit species like sea turtles that feed on jellies, they can negatively impact other species and be a nuisance for fishers, divers, and surfers.

Next time you're visiting a West Coast national marine sanctuary, see if you can spot a mesmerizing Pacific sea nettle gently drifting through the water.
