Stony corals have a patchy distribution in the shallow marine waters surrounding San Salvador Island. They occur as isolated individual colonies, in patch reefs, fringing reefs, and barrier reefs. Stony corals are scleractinian anthozoan cnidarians (there are also non-scleractinian stony corals in the fossil record, such as tabulates and rugosans). They consist of individuals or colonies of gelatinous polyps that secrete hard skeletons of aragonite (CaCO3). Most scleractinian corals live in warm, tropical to subtropical, photic zone environments (the shallow portions of the world’s oceans where sunlight penetrates). Microbes (Symbiodinium - Protista, Dinoflagellata/Pyrrhophyta) called zooxanthellae live in their tissues and need to be in sunlight to make their own food (photosynthesis), which is shared with the host coral animal. Scleractinian corals have stinging cells (nematocysts) in their tentacles that paralyze prey. Diploria brain corals are easily identified by the presence of convoluted, labyrinthiform corallites. In Diploria labyrinthiformis, the convoluted ridges that make up the surface have a prominent median groove. The more commonly encountered species Diploria strigosa (see elsewhere in this photo album) lacks a median groove.
