The Cordell Bank is home to an extraordinary ecosystem, including marine birds, mammals, and other natural resources. The Sanctuary encompasses brilliant and diverse marine life, above and below the water.The upper reef crests of Cordell Bank are carpeted in lush invertebrate cover, including hydrocorals, stony corals, sponges, anemones, hydroids, macroalgae and tunicates, providing critical habitat to a variety of first-year juvenile and adult rockfish species. Cordell Bank is truly a biologically diverse and unique place.
The Sanctuary supports healthy resident populations and is a destination feeding ground for many migratory marine mammals, seabirds, and fishes. Invertebrates proliferate on the Bank and in the surrounding water column.
