Centruroides hentzi, commonly known as the Arizona bark scorpion, is a venomous arachnid found in the southwestern United States and northern Mexico. It is a small species, measuring around 2.5 to 3 inches in length, with a slender body and long, thin pincers. The scorpion's venom is potent and can cause severe pain, but it is rarely life-threatening to humans unless the individual is allergic or has a compromised immune system.
