Scorpions are arachnids and close relatives of ticks, mites, and spiders. There are about 90 species in the United States, the largest being the giant desert hairy scorpion, growing to 5-6 inches long. Scorpions have a long segmented tail that curls up with a stinger on the end. The surfaces of their legs and body are covered with thick hairs that are sensitive to direct touch. The tips of the legs have small organs that detect vibrations in the ground up to a foot away. 1.5″ Hard enamel pin; gold metal.
