How Are Sand Dollars Formed?

Answer

Sand dollars are actually skeletons (also called tests) of a sea creature called a sea urchin. While they are alive, the sand dollars have spines on their tests like other sea urchins. After they die, a combination of decay, erosion, and scavenger fish strips the sand dollar of its flesh and spines, and the currents and tide eventually carry them to the beach, where the sun dries them out and bleaches the color out of them.
