Scorpionfish fluorescing red underwater, photographed at night using blue coloured flashlight and a yellow filter. In the background coral glows green. Blue light excites pigments within some underwater organisms causing them to emit a fluorescent glow. In fish, this may be a means of camouflage, warning or sexual signal. Photographed in the Red Sea, Egypt.
