Several species of Scorpions are native to the desertlands of the Navajo Nation. Scorpions are arachnids, which means that they are closely related to spiders, ticks and mites. Most scorpions on the Navajo Nation grow to 1-2 inches in length. The Navajo Zoo keeps the largest scorpions found in the U.S., the desert hairy scorpion, which can grow to 5 inches. Scorpions are nocturnal predators on insects, spiders, centipedes and other scorpions. Scorpions deliver venom from their sharp tail to catch predators and defend against predators.

Scorpion is named "Séigo" in the Navajo language. Scorpion and other invertebrates are said to have been created in the First World in Navajo tradition. Navajo People respect Scorpion because it can bite and do grave harm.
