"This kind of biofluorescence only happens when blue light hits the amphibian, whose skin—and bones, in the case of the marbled salamander—absorb that wavelength and emit a different wavelength, usually an electric green. (This is not the same as bioluminescence, in which an animal like a deep-sea anglerfish either produces its own light through chemical processes or with the help of a glowing symbiotic bacteria that lives in its body.) To get these images, the researchers flooded the amphibians with blue light and photographed them with a special filter that only allowed the fluorescent light from the animal to hit the camera."
