What is a Sand Dollar Have you ever taken a walk along the beach to collect seashells and found a gray disk shaped like a silver dollar? If so, chances are you found the "shell" of a sea animal known as a sand dollar, that had been washed up by the tide onto the beach. Sand dollars live on the sandy' bottoms of coastal waters. A living sand dollar's body is covered with short, movable spines used for digging and crawling. When the sand dollar dies, the body tissues decay and the spines drop off, revealing the round, flat skeleton. Gray spots form a star-shaped pattern on its back.
