Scorpion are distant relatives of spider, but while spiders bite, scorpion carry their venom in poison glands near the stinger that they carry at the tip of the tail. Many scorpions live in arid areas, such as deserts, where they will shelter from the heat of the day under stones or in the burrow of another animal, and hunt insects at night. Other species live in jungles and shelter under bark during the day. When a scorpion spots prey, it raises its tail ready to strike, and once it has caught its victim paralyses or kills it by stinging it. A scorpion will also raise its tail as a display when it meets anything that it sees as a threat, such as a meerkat or a large
spider. Scorpion range in size from those that are only 1 or 2 cm as full-grown adults to as much as 17 cm. None will deliberately attack a human, except in self-defence so people may get stung if they accidentally disturb one.
