Ocean conditions and undersea topography combine to fuel a rich and diverse marine community around Cordell Bank. The rocky bank is encrusted with colorful anemones, sponges, and corals and provides habitat for species like top snails, decorator crabs, rosy rockfish, lingcod, and giant Pacific octopus. The waters above and around the bank concentrate krill, juvenile rockfish, anchovy, and jellies attracting ocean sunfish, California sea lions, and the blue whale.
