In these animals the five arms have been incorporated into the body and the ossicles form a rigid test with pedicellariae and moveable spines. They also have tube feet that aid the spines in locomotion. The mouth is on the lower surface and has a distinctive chewing apparatus known as Aristotle’s lantern after the famous Greek philosopher who described it.
