Looks like a Bobbit Worm but was found in Santa Barbara, CA (which is not within the range of the bobbit worm…) The animal was brought on to the Wet Deck of the Sea Center for observation under a microscope.
Marine polychaete with eversible proboscis. Found inside and on rotten wood, appears to be feeding on the ship worms inside
