Scorpions (Scorpiones)

Scorpions can range in size from less than an inch to more than 8 inches long, making them one of the larger arachnids. They have a segmented abdomen ending in a long tail with a sharp stinger on the end which contains poison that can paralyze their prey, usually insects and rodents. Most scorpion stings are not fatal to humans, although some in Africa and the Southwestern U.S. can be. One difference between scorpions and other archnids is their large claws, called pedipalps. These are used to grab prey. Some scorpions have as many as six pairs of eyes, more than most other arachnids. Most scorpions are nocturnal and hide during the day.
