Echinoderms (which include starfish) have a water vascular system associated with movement in some species and feeding in others. Water is pumped around the system through the ring canal, lateral canals, radial canals, ampulla, podium and to the sucker feet. This water vascular system has a vacuum effect allowing the starfish to suction its many feet to the substrate and release them at its own will.
