These arachnids are carnivores and generally eat small insects and arthropods.
Slow and wingless, they don't cover much ground, but cling to animals that carry them around – usually other insects, sometimes birds and mammals.
A well-developed venom gland is located at the end of their large pincers; pseudoscorpions capture prey by paralyzing or killing it with this poison. Like other arachnids, they use a form of external digestion, which takes place inside the prey’s body, and consume what is essentially pre-digested food.
Pseudoscorpions hold their pedipalps in front of their head when they move. When disturbed, they will pull the pincers over their body and come to a halt. They can move backwards.
Chelifer cancroides, the most frequently observed pseudoscorpion, lives solely in homes. They are generally found in the bathroom, where they are attracted by moisture in the bathtub or sink and cannot escape up the smooth sides.
