# Sea Potatoes

A sea potato is a type of sea urchin, specifically the species Echinocardium cordatum, known for its heart shape and preference for burrowing in sandy seafloors. They are called “sea potatoes” due to their resemblance to the root vegetable, both in shape and the way they are found buried in the sand.
