DESCRIPTIONFaviidae is a species of brain coral found in the Red Sea. When viewed under blue light a bright green glow is emitted by the coral, this is caused by fluorescent pigments within the coral polyps. As well as creating a beautiful glow these pigments act as a sunblock protecting the coral from intense sunlight in the shallows. Image taken in Marsa Shagra, Egypt.
