It’s Hard to Believe This Sand Dollar is a Living Animal

Sand dollars are a mysterious throwback to earlier times. Seeing them reminds us that animals from long ago still exist today. It’s rare to see a living one, but here you see how they look so much different from their dead counterparts that wash up on the beach.

Sand dollars feed on some of the tiniest ocean animals known to human beings. They both move food toward their mouth and move along the ocean floor on a multitude of furry spines. They have a tiny little mouth with five sets of teeth, and they are some of the weirdest animals you will find at the beach.
