Fluorescent Fattail scorpion (Androctonus crassicauda)

Fun fact about scorpions, they light up under UV light. So if you bring a blacklight to the desert, this is what you see.

The fluorescence is a result of the hyaline layer of the scorpion’s outermost layer of exoskeleton (the cuticle) absorbing UVA and emitting a greenish light..
