Sea Urchin
oil on canvas

Sea urchins are related to starfish and sand dollars and date back 500 million years. Their spines, are a means of defense and give them the nickname "hedgehog of the sea." Sea urchins move by means of tiny tube feet the same way starfish and sand dollars do and their teeth are so strong that they can bore holes in rocks and make a place to hide from prey..
