Pseudoscorpions of the family simple phoresy. They may have two, four or no eyes.

They have two very long pedipalps with palpal chelae pincers which strongly resemble the pincers found on a scorpion. The pedipalps generally consist of an immobile "hand" and "finger", with a separate movable finger controlled by an adductor muscle. A venom gland and duct are usually located in the mobile finger; the venom is used to capture and immobilize the pseudoscorpion's prey.

During digestion, pseudoscorpions pour a mildly corrosive fluid over the prey, then ingest the liquefied remains.

Kangaroos and Commensalism

A coloured etching of a pseudoscorpion 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 like true scorpions and the Tetrapulmonata. Instead they breathe exclusively through spiracles. Behavior[ edit ] Phoretic pseudoscorpion on a fly, Germany Some species have an elaborate mating dancewhere the male pulls a female over a spermatophore previously laid upon a surface. The young go through three molts over the course of several years before reaching adulthood.

Many species molt in a small, silken igloo that protects them from enemies during this vulnerable period. They are active in the warm months of the year, overwintering in silken cocoons when the weather grows cold. Smaller species live in debris and humus. Some species are arborealwhile others are phagophileseating parasites in an example of cleaning symbiosis. Some species are phoretic[9] others may sometimes be found feeding on mites under the wing covers of certain beetles.
