What Eats Sea Urchins

The sea urchin is a type of marine echinoderm that has a round body and five spines. It is found in shallow, sandy areas of the ocean, including the intertidal zone.

Sea urchins are not only eaten by humans but also by other animals in the ocean such as fish, seabirds, and sea otters. They are eaten because they provide an important source of nutrients for these animals. Sea urchins feed on algae and other phytoplankton, which provides them with energy to grow.

Sea urchins are a type of invertebrate that has an internal skeleton made up of calcite plates (like a coral) called ossicles.
