Why are starfish hard to pull of rocks?
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.
What is the body division of a starfish?
A starfish has radial symmetry
How does starfish move?
Water comes into the system via the madreporite. It is then circulated from the stone canal to the ring canal and into the radial canals. The radial canals carry water to the ampullae and provide suction to the tube feet. The tube feet latch on to surfaces and move in a wave, with one body section attaching to the surfaces as another releases.
