The reef includes forests of bull kelp up to 100 feet (30 m) long, which provide protective habitat for numerous animals, including the bat ray, big skate, broadnose sevengill shark, cabezon, kelp bass, leopard shark, spiny dogfish, kelp greenling, plumose anemone, and numerous species of rockfish.[3] The reef also supports more than 39,000 seabirds, including 5% of the common murre nesting population in Oregon.[2] The Oregon Coast Aquarium in Newport, Oregon contains a simulated version of Orford Reef in its Passages of the Deep exhibit.[4]
