Sea Stars and Urchins off Antarctica

Sea stars (Odontaster validus) and sea urchins (Sterechinus neumayeri) spread over an algae-covered seafloor off the coast of Antarctica. These two species are often found living in association with one another, and they were studied (together and separately) by NaGISA, the Natural Geography In Shore Areas project, during the Census of Marine Life.
