The individual corals are quite beautiful. In the picture above there is an Elkhorn Coral, Acropora palmata, on the left and a Common Sea Fan, Gorgonia ventalina, on the right. Notice, however, the white areas where the underlying corals have died and bleached. Corals in many parts of the world are dying back, probably due to a combination of climate change and the effects of development, partially forced by an increasing population size.
To the left is a Golf Ball Coral, Favia fragum.
