Scorpion

Scorpion, any of an order (Scorpionida) of terrestrial arachnids having two claws held in front of the head and a stinging tail curled forward over the back. All scorpions have a poisonous sting but few are dangerous to humans. The sting is usually used in defense or, with the palps, in catching prey. Scorpions are restricted to dry, warm regions of the world and feed on grasshoppers, crickets, spiders, and other arthropods.
