"As soon as we saw this fluorescence, we realized that the web-footed geckos must use a new mechanism: the bright, neon-green fluorescence patterns were clearly produced in the skin of the lizards," explains David Prötzel, first author of the study. UV light is composed of wave lengths slightly too short for most humans to see. A few specimens simultaneously produce different colors when viewed under long wave and short wave UV light, while a number of fluorite specimens’ phosphorescence (glow without a visible light source) in a third color.

The platypus is so strange that British scientists in the late 18th century were dubious as to its existence, even though a preserved pelt had been sent to London. GFP stands for green fluorescent protein (the official name for the molecule) and is, imaginatively, a protein that fluoresces green in the presence of UV light . The concomitant formation of metallic Bi nanoparticles and oxygen vacancies was successfully achieved within Bi/BiOBr/RGO composites by facile and green UV-light exposure. The web-footed gecko (Pachydactylus rangei) from the Namib desert fluoresces neon-green along its flank and around the eye under strong UV-light.
