The emperor scorpion or imperial scorpion (Pandinus imperator) is a species of scorpion native to Africa. The emperor is one of the largest species of scorpion in the world, with adults averaging about 8 inches (20 cm) in length. The emperor's size, relatively low toxicity, and life span make it the most popular scorpion in the pet trade, which has led to such over-collecting in the wild that it is now a CITES-listed animal, meaning it is threatened with extinction if exportation and other threats, such as development, are not regulated.
