Pseudoscorpions are small arachnids with a twelve segmented abdomen and pincers that resemble those of true scorpions. Usually between 2 to 8mm, they can be yellowish-tan to dark-brown, the paired claws often a contrasting color. They may have two, four or no eyes and two comparatively long pedipalps (pincers) containing venom. Pseudoscorpions were first described by Aristotle, who probably found them feeding on booklice. They practice an unusual form of commensal behaviour, hitching rides on other animals, such as beetles. This behaviour is called "phoresy". They have silk glands in their jaws for building hibernation and egg-laying retreats. There are around 25 described families worldwide, with about 150 species in 17 families found in Australia.
