Echinoderms, such as starfish and sea urchins, have a unique water vascular system that aids in movement and feeding through the use of tube feet. They also have an endoskeleton made of calcium carbonate plates. Arachnids, crustaceans, and mandibulates do not have a water vascular system or tube feet.
