These nocturnal, predatory animals generally feed on a variety of insects, spiders, and even other scorpions. The larger scorpions occasionally feed on vertebrates, such as small lizards, snakes and mice. Scorpions can survive without feeding for six months. Despite their villainous appearance, scorpions are not aggressive hunters but rather lie and patiently wait for their next meal. Scorpions enter structures in search of shelter and water.
