Sand Dollars

Facts About

 Living in south eastern United States, we have visited many beaches and I can tell you that sand dollars are elusive and fascinating creatures, but can sand dollars hurt you? 

While sand dollars do have spines, they are soft and do not pose any threat to humans beyond some minor scrapes.

Living sand dollars come in a wide range of colors, from green to red and even purple. Adults typically grow from 3-4 inches in diameter.

Sand dollars often live in giant colonies, with over 600 individuals in one congregation.

When the waters are calm, sand dollars will orient themselves upright and bury themselves halfway out of the sand.

They can easily catch tiny, free-floating organisms such as larvae, algae, and diatoms in this position. Sand dollars are omnivorous.

Sand dollars typically live to be around 10 years old, and we can determine their age by the number of rings they have on their exoskeleton.
