Occasionally distinct in appearance to their fossil ancestors, living forms nonetheless provide clues of ancient crinoidal modes of life. An array of branching arms (brachia) is arranged around the top of a globe-shaped, cup-like structure (calyx) containing the main body of the animal. Crinoids, members of the phylum Echinodermata, are passive suspension feeders and catch plankton without producing an active feeding current. Today, the stalked forms are known only from deep water habitats, where flow conditions are rather constant and feeding velocities relatively low. For feeding, they form a characteristic parabolic …The body lies in a cup-shaped skeleton (calyx) made out of interlocking calcium carbonate plates. Arms attached to the calyx also have a plated skeleton and are used to capture food particles. In most species, the calyx is anchored to the sea floor by a stem made of a stack of disk-shaped plates.The three main sections of a crinoid give it the lily-like appearance.
