Scorpions are one of the most recognized predatory arthropods. They have eight legs and a pair of grasping pinchers and a narrow often curved forward tail with a venomous stinger at the end. There are thirteen families and about 1,750 described species and subspecies of scorpions. Scorpions are found on all major land masses except Antarctica. The oldest known scorpions lived around 430 million years ago in the Silurian period. Scorpions are known to glow a vibrant blue-green when exposed to certain wavelengths of ultraviolet light. This is due to the presence of fluorescent chemicals in the cuticle. One fluorescent component is now known to be beta-carboline. A hand-held UV lamp has long been a standard tool for nocturnal field surveys of these animals. This fluorescence is believed to have an active role in scorpion light detection. All known scorpion species possess venom and use it primarily to kill or paralyze their prey so that it can be eaten. In general, it is fast-acting, allowing for effective prey capture. However, as a general rule they will kill their prey with brute force if they can, as opposed to using venom. It is also used as a defense against predators. Of all the known species of scorpion, only 25 have venom that is deadly to humans. These paperweights are a perfect way to explore these fascinating specimens from every angle without worrying about harming the specimen. Different batches may have a slight yellow tint, but this will not affect the visibility of the specimen.
