There are several species of sand dollars found in marine ecosystems, including the common sand dollar (Echinarachnius parma) and the keyhole sand dollar (Mellita quinquiesperforata). These creatures are echinoderms that belong to the same family as sea urchins and starfish. Sand dollars are known for their flat, round bodies and distinctive five-part radial symmetry.
Sand dollars are part of the class Echinoidea and primarily belong to the family Clypeasteridae. The most commonly recognized types include the common sand dollar (Echinarachnius parma), found in shallow coastal waters, and the keyhole sand dollar (Dendraster excentricus), which has distinctive holes on its surface. Other notable varieties include the Pacific sand dollar and the Atlantic sand dollar, each adapted to their specific marine environments. These species vary in color, size, and habitat preferences, but all share the characteristic flat, disc-like shape.
