Sonoran gopher snakes (Pituophis catenifer affinis) are a captivating snake species native to the southwestern United States and northern Mexico. These non-venomous snakes are known for their impressive size, with adults reaching lengths of up to 6 feet (1.8 meters) or more. Their coloration varies, but they typically have a background color of tan or yellow with dark brown or black blotches along their bodies, providing effective camouflage in their desert habitats. Despite their formidable appearance, Sonoran gopher snakes are generally docile and harmless to humans, preferring to avoid confrontation by hissing loudly and mimicking the behavior of rattlesnakes when threatened.

One of the most fascinating aspects of Sonoran gopher snakes is their diet and hunting strategy. As their name suggests, they primarily feed on gophers and other small rodents, using powerful constriction to subdue their prey. These snakes are excellent burrowers and are known to excavate rodent burrows in search of food. They are also adept climbers and can often be found basking in the sun on rocks or low vegetation. In captivity, Sonoran gopher snakes require a spacious enclosure with ample hiding spots and climbing structures to accommodate their active lifestyle. Their size, interesting behaviors, and relatively calm demeanor make them a popular choice among reptile enthusiasts.
