The clypeasteridae also known as the sand dollar, are round and semi-flat organisms with spines lining the underside of the body and elongated genital papillae aiding its survival and reproduction. The spines help them move along the sea floor to feed and increase in density to burrow the sediment while avoiding predators. The elongated genital papillae allow the sand dollar to asexually reproduce undisrupted under the sediment as the gametes are released into the water and later fertilized by male clypeasteridae.
