The sand dollar habitat is the sandy or muddy ocean floor of coastal areas and bays. Dead sand dollars are often found washed up on beaches. They are called sand dollars because they look like a large, round, flat coin. Alive however, sand dollars look like fuzzy cookies. Sand dollars have tube feet on their top and underside. They use the underside tube feet to move around on the ocean floor. Their mouth is also on their underside. They sift through the sand using their tube feet to find food.
