  • The internal skeleton of an echinoderm is made of calcium carbonate bony plates that are bumpy or spiny for protection.

    An echinoderms water vascular system is a system of canals that carry food and oxygen and remove wastes.

    The water vasuclar system also helps an echinoderm move.

  • Asteriodea (AS-tuh-ROID-ee-uh)

    sea stars5 to many arms

  • A starfish is able to re-grow its arms.

    A starfish uses its tube feet to move and to open its food (bivalves).
