The Pacific sand dollar is essentially just an irregular sea urchin and shares many of its characteristics. It has a calcium carbonate fused exoskeleton, called a test, which is flattened, accounting for its disc like appearance.
Like all echinoids, sand dollars have a water-vascular system, which controls their tube feet and spines, used to feed, move, and even to extract oxygen from the water. They are suspension feeders, often burying one end of their bodies in the sand to catch floating prey with their raised edge, before passing them to their mouths. They often gather in large groups, and orient themselves according to the surrounding current. These little fellows are eccentric, and often overlooked, but they get around, bet your bottom dollar.
