Answer:

Sand dollars, like sea stars, are echinoderms, a group that also includes brittle stars, sea urchins and sea cucumbers.

Explanation: Eccentric sand dollars are common on sandy seabeds in the subtidal zone and their tests frequently wash up on sandy beaches. ... excentricus are dark colored and covered with tiny spines.
