Brittle Star

Ophiothrix spiculata

This isn't a mass of hairy worms. It's the arms of a Spiny Brittle Star, a cousin of the sea star. The Brittle Star hides under a rock or behind some kelp, and sticks out a couple of arms to get food. The hairy-looking bristles on its arm catch tiny, floating pieces of dead plants and animals and pass them down the arm to the central mouth. Fishes think Brittle Stars taste great. If a fish grabs an arm, the arm just breaks off and the Brittle Star grows another one.
