The Phyla Echinodermata has starfish and sea urchins in it. Starfish and Sea Urchins have 5 part radial symmetry. Most reproduction in Echinoderms is sexually but asexual reproduction also occurs. The body plan of Echinoderms is shifted during their development into an adult. They are bilaterally symmetric as larva, but as they develop in to adults, their radial symmetry begins to show. Their water vascular system is a hydraulic system. They use this water system for movement. I find it interesting that some of the species in phyla echinodermata can regenerate their body parts.
