How do echinoderms use their endoskeleton like an exoskeleton?
Echinoderms, such as sea stars and sea urchins, have an endoskeleton made of hard plates called ossicles that lie inside their bodies.

It allows echinoderms to control their body shape and movement, just like an exoskeleton does for other invertebrates.

How is parapodia different from tube feet?
Parapodia are paired appendages found on polychetes, or marine worms, which are used for movement. Tube feet are found on echinoderms, like sea stars, which are also used for movement.
