Coral Bleaching at Hawaii

Antler coral (Pocillopora grandis) bleached white by the compounding effects of an El Nino with global warming photographed while scuba diving the Kona coast, Hawaii Island. Excessively warm seawater temperature is stressful to live corals resulting in coral bleaching. Corals get their colors from symbiotic algae of the genus Symbiodinium, a type of dinoflagellate called zooxanthellae. When stressed corals expel their symbiotic zooxanthellae the live coral turns white.
