    They have spiny skins, internal skeletons and elaborate hydraulic systems used in locomotion and food getting - and they all live in the sea. Examining echinoderm life-styles shows that seastars (Class Asteroidea) are predators, brittle stars and basket stars (Class Ophiuroidea) are detritus feeders, urchins and sand dollars (Class Echinoidea) are herbivores, sea cucumbers (Class Holothuoidea) feed on detritus and plankton.
