Giant Desert Hairy Scorpion
Hadrurus arizonensisAlso known as Giant Hairy Scorpion, Arizona Desert Hairy Scorpion
Giant desert hairy scorpions are North America's largest arachnids of their order, tunneling deep underground to escape oppressive desert heat. Covered in sensitive brown hairs that detect air currents and ground vibrations, they hunt aggressively under the cover of dark. On warm nights, these formidable predators stalk nocturnal insects and small lizards using their powerful pincers and venomous stingers.
