Phylum Echinoderm
Echinoderms are radial symmetric animals that have water vascular systems. Using this water vascular system enables the animal to move and hold onto prey. Reproduction can be asexual and sexual. Asexual reproduction is usually by the regeneration of a broken arm or by the organism tearing itself in half. Sexual reproduction occurs as echinoderms release gametes into the ocean. Once the egg is fertilized, it will develop into larvae that will change into the typical echinoderm features.
