Eupatagus Antillaruim Sea Urchin

Sea urchins are a type of echinoderm which is still alive and living relatively unchanged today. They live at the bottom of soft ocean floors and have long spines protruding from their central body. They move along the bottom of the ocean using many small feet while feeding on various plant and animal matter on the bottom.
