The sand dollar (Clypeaster sp. Family Clypeasteridae) a flat, round type of sea urchin, is specially adapted to burrowing in sand. The star shape is due to its set of five pores arranged in a petal-like pattern through which it moves sea water into its internal water-vascular system. It's the latter that allows the sand dollar to move about. A link is provided below.
Surprisingly, the actual name for a group of sand dollars is "a fortune." The term "sand dollar" refers to the round flat shape of the rigid endoskeleton which apparently reminded American sailors and sea-farers of a large coin when they spoted them washed up on beaches, bleached a dazzling white by the sun. This comparison to coinage and money led to the eventual use of the term "fortune" to describe a large group of these marine animals, which can congregate by the hundreds on sandbars just below the surface of the sea floor.
