Few treasures discovered while beachcombing are as recognizable as the Common Sand Dollar. With its delicate five-petal star design and smooth, porcelain-white appearance, this fascinating marine animal has become one of the most beloved beach finds along North America's coastlines. Whether you're strolling the shoreline searching for seashells or admiring ocean-inspired beach jewelry, the Common Sand Dollar is a timeless symbol of the sea's natural beauty.
Unlike seashells made by snails or clams, the Common Sand Dollar is actually the skeleton, or test, of a flattened sea urchin. While alive, it is covered with thousands of tiny purple or brown velvety spines that help it burrow beneath the sand and move across the ocean floor. After the animal dies, waves gradually bleach the test into the familiar white sand dollar treasured by beachcombers.

Living sand dollars spend nearly their entire lives buried just beneath the sandy seafloor in shallow coastal waters. They often gather in large colonies where ocean currents provide a steady supply of microscopic algae and organic particles to feed upon.
After storms, strong waves may wash empty tests ashore, creating exciting opportunities for beachcombers.
If you're hoping to add a sand dollar to your beachcombing collection, timing is everything.
The best opportunities include:
Remember that living sand dollars should always be returned to the water. Collect only naturally bleached, empty tests to help protect marine ecosystems and future generations of ocean life.
