Are Basket Stars, Sea Stars?

The basket star, Gorgonocephalus eucnemis, is basically a fancy brittle star. After attaching to a rock or other firm substrate, an adult basket star will spread its five intricately branched arms into the water to catch tiny zooplankton (crustaceans, arrow worms, and sometimes fish larvae and jellies). Hooks on the arms snag the prey items which are then rolled up in mucus strings within the tiny branchlets.
