Arthropods of the order scorpiones, of which 1500 to 2000 species have been described. The most common live in tropical or subtropical areas. They are noctural and feed principally on insects and other arthropods. They are large arachnids but do not attack man spontaneously. They have a venomous sting. Their medical significance varies considerably and is dependent on their habits and venom potency rather than on their size. at most, the sting is equivalent to that of a hornet but certain species possess a highly toxic venom potentially fatal to humans.
