Sand dollars are radially symmetrical and have an internal skeleton but no backbone. This belongs to echinoderms.
Echinoderms are known for their radial symmetry and pentamerous bodies (five or more limbs, typically grouped two on the left, one on the middle, and two on the right).
The body is divided into five equal sections, each of which has a duplicate set of different internal organs. Although brittle stars lack a heart, brain, or eyes, some of them appear to have light-sensitive areas on their arms.
Echinoderms have tube feet, which resemble tentacles and have suction pads at the ends. The extraordinary vascular system that controls these tube feet hydraulically.
