Sand dollars are echinoderms, meaning spiny skin. Sand dollars live on sandy bottoms, and have the shape of an extremely flattened disk. They burrow into the sand and use their tube feet to feed, and spines to crawl along the bottom. They display radial symmetry, and have a hard external test composed of calcium carbonate. In living individuals, it is this test that has a spiny covering.
