Caption: Sarcophyton sp. coral, with extended feeding polyps, fluorescing green under blue light. Some species of coral emit a fluorescent glow. It is thought the glow may attract symbiotic algae, or protect the coral from the intense ultraviolet light of the sun in shallow water. Photographed in the Red Sea, Egypt.
