What are equipped with spiny skins and peculiar tube feet?

Echinoderms are named for their “spiny skin.” However, the spines aren't on their skin. ... A unique feature of echinoderms is their water vascular system. This is a network of canals that extend along each body part. In most echinoderms, the canals have external projections called tube feet (see Figure below).
