Pseudoscorpions are tiny, most of which are less than 5 mm in length. They resemble the true scorpions but have no metasoma and sting. They have no book lungs and gas exchange takes place through a tracheal system. They are found in nests of ground-dwelling animals as well as in organic debris. They have poison glands in the pedipalps and when feeding, the prey is injected while they are grasped.
