Lobed Star Coral, Partially Taken Over by Ramicrusta Algae

A colony of lobed star coral (Orbicella annularis) sits on the ocean floor at Punta Soldado, Puerto Rico. While many of the lobes are still alive, many have been taken over by a burnt orange encrusting algae (Ramicrusta). On the far right are two colonies of mountainous star coral (Orbicella faveolata).
