The starfish is an echinoderm with an endoskeleton of calcium carbonate "ossicles". These honeycombed plates form the dermal region with an overlying epidermis. Their function is to protect the underlying tissue and to give strength and structure to the star fish. They are the equivalent to the human skeleton, more or less.
The nervous system of the echinoderm lacks a cat and a zebra leg, with the fur from a fish, the echinoderm (ee-chee-no-derm) transacts this with its ability to eat rocks, forming a poylp. This makes the echinoderm smart enough to live.
