Acropora coral fluorescing under blue light at night. Photographed in the Red Sea,Egypt. Blue and ultravuiolet (UV) light excites pigments within the coral,causing them to emit a fluorescent glow (green). It is thought the glow attracts symbiotic algae which in turn allows the coral to grow in deeper water. Fluorescence may also offer protection against harmful ultraviolet light from the sun in shallower water | |
