Spiny brittle star
Those aren't worms, they're brittle stars, sea star cousins that bury themselves for protection. They leave an arm or two free to catch bits of food, but sometimes their wave hails a hungry fish.

Brittle stars occur in incredible numbers on the sandy seafloor. In kelp forests near La Jolla in southern California, millions of them may carpet the seafloor in layers up to an inch thick!
Brittle stars live in an incredible range of water depths—from the shoreline down to 6,755 feet (2,059 m).
