Sand dollars actually live on the bottom of the ocean or under the ocean floor. They can move throughout the sediment. The have things called Podias which move the sand dollar's food towards its food opening. They have few natural predators, some of them are ocean pouts and sunflower starfish. You will commonly find them broken mostly because of the undertow and the tides. Sometimes you will find a sand dollar and it will most likely be a dead one.
Sand dollars are not very rare and can be found in sandy ocean floors around the world, particularly in shallow coastal waters.
The skin of the sand dollars have small spines, which in turn has tiny hairlike structures called cilia. The cilia helps the sand dollars to catch any organic matter floating around for food.

Sand dollars grow and develop their unique skeletal structure through a process called biomineralization. They absorb calcium carbonate from the ocean water and use it to build their hard, flat skeletons. As they grow, the sand dollars' skeletons develop distinctive patterns of pores and spines, which help them move and protect themselves.
