  • 1. Living echinoderms are characterized by an extensive water vascular system developed from the larval left hydrocoel, a complex, multi‐plated endoskeleton with stereom structure, and pentamery. Fossil evidence shows that stereom evolved before pentamery, but both were acquired during the Lower Cambrian.
