The Book Scorpion (pseudoscorpion)

A pseudoscorpion, also known as a false scorpion or book scorpion, is an arachnid and can be found on Sibuya Game Reserve.

Pseudoscorpions are generally beneficial to humans since they prey on clothes moth larvae, carpet beetle larvae, booklice, ants, mites, and small flies. They are tiny and inoffensive, and are rarely seen due to their small size, despite being common in many environments. Pseudoscorpions often carry out phoresy, a form of commensalism in which one organism uses another for the purpose of transport.

Pseudoscorpions spin silk from a gland in their jaws to make disk-shaped cocoons for mating, molting, or waiting out cold weather. However, they do not have book lungs as most of their closest relatives, the spiders, do. They breathe through spiracles, a trait they share with the insects.
