Green brittle star

These starfish have five slender arms that extend out from their central circular bodies. Brittle stars are adapted to a wide range of environments, from shallow shoals to the deep sea, and get their food from a variety of sources, including plankton, sediment on the seafloor, and the remains of other organisms.
