Scorpions are arachnids, close relatives of spiders, ticks and mites. There are approximately 1,300 species of scorpions world-wide. They are very common in the Southern and Southwestern States. About 40-60 species occur right here in Arizona, although many are un-described. While they are commonly thought of as desert animals, they do in fact occur in other habitats as well, including grasslands, pine forests, rain forests, deciduous forests and caves.
Most scorpions are not poisonous with the exception of the Bark Scorpion which reside in Arizona (see below for details). Even with non-poisonous scorpions, young children, the elderly and individuals that may be allergic to scorpion venom can experience serious health consequences if stung and should seek medical attention immediately.
