All echinoderms possess a unique water vascular system, which aids in locomotion, feeding, and respiration through the use of tube feet. Additionally, they exhibit radial symmetry, typically as pentamerous (five-part) symmetry in adults, allowing for a symmetrical arrangement of body parts around a central axis. These features are key to their classification and function within marine ecosystems.
its your face
Echinoderms have tube feet, with the exception of urchins, which have spines. They are invertebrates. They also have no organs or eyes.
