What Is A Sand Dollar?

A sand dollar is a highly flattened form of urchin of the order Clypeasteroida. As an echinoderm, they have a pentameral symmetry to their body organization, a water vascular system, and an endoskeleton made of calcite plates. They live in shallow marine environments just below the low tide line, buried in the sand or mud. They are active predators, feeding on crustacean larvae, small copepods, diatoms, and algae.

The are basically circular in shape, though some having flattened or indented sides. Living, they are covered with velvety-looking spines that they use to move.

These are part of the respiratory system and leave an easily identified “flower” on the skeleton.
