Hadrurus arizonensis

Fascinating Facts

Physical Characteristics

This species is usually yellow with a dark top and has lobster-like pincers. It gets its common names from the brown hairs that cover its body. These hairs help it to detect vibration in the soil. They can grow up to a length of 14 cm (5.5 in).


The giant hairy scorpion is distributed throughout the Sonora and Mojave deserts. In Mexico, the species' range flanks the Sea of Cortez in Sonora and Baja California Norte. In the United States, it is found in the western two thirds of Arizona, the Colorado Desert and Mojave Desert regions of southern California, southern Nevada, and extreme southwestern Utah. They are usually found in and around washes or low-elevation valleys where they dig elaborate burrows.

Its diet consists of large insects, spiders, and small vertebrates.

Social Behavior

This is an aggressive and active scorpion, which, as with all scorpions, is nocturnal. When a suitable victim wanders by, the scorpion grabs the doomed creature with its pincers and stings the prey. After the prey is immobilized, the scorpion tears the carcass apart with its pincers and begins feeding.
