THE CHARACTERISTICS OF ECHINODERMS Classified within their own phylum within the animal kingdom, sponges have some of the simplest body organization in terms of cellular interaction. FEEDING: Echinoderms family will feed REPRODUCTION: All arthropods lay and fertilize eggs. Once fertilized, the eggs will wait a gestation period. During this fertilization and gestation period, many female arthropods including sheep crab and the California spiny lobster will store the eggs close to the body until the young have developed and hatched. Once hatched these small creatures will float on the current feeding on other plankton until they settle out on the ocean floor. Once they have settled the arthropods will live out the rest of their lives as bottom dwelling organisms. THE BODY STRUCTURE OF ECHINODERMS: The body shape of echinoderms are bilaterally symmetrical. THE COMPONENTS OF ECHINODERMS: Echinoderms have multiple digits and vary widely in size. Development of these pages is currently ongoing.
