  • Many coarse spines cover the upper surface that have pincers (those pincers help obtain food by paralyzing prey)
  • They have an endoskeleton;bony-like plates of calcium that are bumpy or spiny
  • Radial symmetry with five parts or multiples of fives (like starfish have radial symmetry and five tentacles (most of them do))
  • A water-vascular system;a system of fluid-filled internal tubes that carry food or oxygen, removes wastes, and helps echinoderms move (tubes eventually connect to tube feet).
  • Tube feet;very strong structures that allow them to move and obtain food (act like sticky suction cups)
