- 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)
