Scorpion (Scorpiones)
Scorpions have adapted to a wide range of environmental conditions and can now be found on all continents except Antarctica. Scorpions number about 1750 described species, with 13 extant families recognized to date. Only about 25 of these species are known to have venom capable of killing a human being. Scorpions are also known to glow a vibrant blue-green when exposed to certain wavelenghts of ultraviolet light such as that produced by a black light, due to the presence of fluorescent chemicals in the cuticule. This fluorescence may have an active role in scorpion light detection.
