Sand dollars are NOT a type of sea urchin, but they are related to them. They are both 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.
Sand dollars are a type of sea urchin specially adapted to burrowing in sand. In contrast to most other sea urchins, the bodies of sand dollars are clothed with hard out sides
