Echinoids are invertebrate marine animals that are found throughout the world. The group includes sea urchins and sand dollars. Echinoids exhibit pentaradial symmetry and have a skeleton, or test, of fused calcitic plates embedded in the skin. Tube-feet are used for feeding and respiration, and spines are involved in locomotion and defense against predators.Echinoids More...
