Sea lily

About 2,400 meters (a mile and a half) below the surface of Monterey Bay, this "sea lily" clings to the wall of Monterey Canyon. Marine biologists call this animal a "stalked crinoid." Crinoids are relatives of sea stars and sea urchins that live by capturing tiny food particles that drift by on deep-ocean currents. The stalk on this crinoid keeps it up above the muddy seafloor, where the currents are slightly stronger. Like many sea stars, this stalked crinoid has five-fold symmetry, and a mouth located at the center of its feathery arms.
