[Description]
This is a small sea urchin that inhabits shallow sandy bottoms. Its body is flattened and oval-shaped, densely covered with short spines on its surface. It is named Usukashipan (thin sweet bread) because its shape resembles a thin sweet bread. It lives buried in the sand, feeding on organic matter and detritus. It burrows by moving sand grains with the tube feet and spines on its body surface, protecting itself from predators and playing a role in nutrient cycling on the seabed, acting as a cleaner of the sea.
