What are sandbabies?

Sandbabies, also known as sand dollars, are flat, burrowing sea urchins belonging to the order Clypeasteroida. They are characterized by their round, disc-like shape and a hard, skeleton-like shell that is often found washed up on beaches. Sandbabies are typically found in shallow coastal waters and play a role in the marine ecosystem by feeding on organic matter and algae. Their distinctive appearance and delicate structure make them popular among beachcombers and collectors.
