The Vinegarroon is a specific species of scorpion. It is in the Order Uropygi, known as the Whip Scorpions. Whip Scorpions have a stingerless, whip-like tail, which is used as a sense organ, not a weapon. The Vinegarroon (Mastigoproctus giganteus) is a scorpion that shoots acetic acid (vinegar) in mist form when it is threatened. The Vinegarroon contains no venom, but they do have powerful claws. They are nocturnal carnivores. They are found in the Desert Southwest of the United States and Mexico.
