Species of scorpion
The striped bark scorpion and the closely related Baja California bark scorpion are also called bark scorpions. The Arizona bark scorpion (Centruroides sculpturatus, once included in Centruroides exilicauda) is a small light brown scorpion common to the Sonoran Desert in the southwestern United States and northwestern Mexico. An adult male can reach 8 cm in length (3.14 inches), while a female is slightly smaller, with a maximum length of 7 cm (2.75 inches).

Arizona bark scorpions are eaten by a wide variety of animals such as pallid bats, birds (especially owls), reptiles, and other vertebrates. Some examples include spiders, snakes, peccaries, rodents, and other scorpions. Development, pesticides and collecting scorpions for research or the pet trade also reduces the bark scorpion population. The painful and potentially deadly venom of Arizona bark scorpions has little effect on grasshopper mice. Scientists have found the scorpion toxin acts as an analgesic rather than a pain stimulant in grasshopper mice.

Arizona bark scorpions have a gestation period of several months, are born live, and are gently guided onto their mother's back. The female usually gives birth to anywhere from 25 to 35 young. These remain with their mother until their first molt, which can be up to three weeks after birth. Arizona bark scorpions have a life expectancy of about six years. Arizona bark scorpions, like most other scorpions, are incredibly resilient. During US nuclear testing, scorpions, along with cockroaches and lizards, were found near ground zero with no recorded adverse effects.

An antivenom was developed for this species at Arizona State University by Dr. Herbert L. Stahnke, and produced in quantities sufficient to treat individuals within the state of Arizona. This antivenom was not FDA approved, but use within the state of Arizona was allowable and very successful in shortening the duration of symptoms and hospitalization. Production of this antivenom ceased by 2000 and the product was unavailable by 2004. A Mexican produced antivenom, Anascorp [Antivenin Centruroides (scorpion) F(ab′)2, Laboratorios Silanes, Instituto Bioclon SA de CV], received FDA approval on August 3, 2011, and is now in use.

Arizona poison control centers suggest immediate medical attention if severe symptoms occur, particularly in young children. pesticides, glue boards, and removing any scorpion congregation areas in the vicinity of the building.
