The Arizona gopher snake belongs to the reptilian class Reptilia, order Squamata, and family Colubridae. Within the Colubridae family, it is classified under the subfamily Colubrinae. The scientific name, Pituophis catenifer affinis, reflects its close relationship with other gopher snake subspecies found throughout North America.

Quick Facts

  • The Arizona gopher snake is non-venomous, relying on constriction to subdue its prey.
  • It is a constrictor snake, meaning it wraps its muscular body around its prey to suffocate it.
  • These snakes are renowned for their mimicry skills, often imitating the appearance and behavior of rattlesnakes to deter potential predators.
  • They play a crucial role in maintaining ecological balance by controlling rodent populations.
  • Gopher snakes are excellent climbers and swimmers, enabling them to adapt to various habitats.


The Arizona gopher snake showcases an impressive combination of colors and patterns. Its slender body can reach lengths of up to six feet or more. The primary coloration ranges from light gray to pale yellow, featuring dark blotches along the back. The head is typically light-colored, and some individuals exhibit distinct markings around the eyes, resembling a mask.

These snakes possess smooth scales, allowing them to navigate their underground habitats effortlessly. Their eyes are round and possess vertically elliptical pupils. The scales on the ventral side are usually lighter in color, providing a striking contrast to the darker dorsal scales.

The Arizona gopher snake’s appearance often leads to confusion with the venomous western diamondback rattlesnake due to its similar coloration and patterns. However, upon closer observation, distinguishing characteristics, such as the lack of heat-sensing pits and a rattling tail, help differentiate between the two species.

Distribution and Habitat

The Arizona gopher snake is endemic to the arid regions of the southwestern United States, primarily found in Arizona, as its name suggests. It also occurs in neighboring states such as New Mexico, Nevada, Utah, and California. Within these states, they inhabit a variety of environments, including deserts, grasslands, and scrublands.

These adaptable snakes can thrive in diverse habitats, ranging from rocky hillsides to sandy washes. They are well-suited to arid conditions, utilizing burrows and crevices to escape the scorching heat during the day. The availability of rodent prey in these habitats contributes to the gopher snake’s distribution.

Biology of the Arizona Gopher Snake

The Arizona gopher snake possesses remarkable biological adaptations that enable it to survive in its arid environment. These snakes are ectothermic, meaning they rely on external sources of heat to regulate their body temperature. Basking in the sun allows them to elevate their body temperature for optimal metabolic functioning.

Gopher snakes are primarily diurnal, becoming more active during the cooler parts of the day. They are known for their impressive burrowing abilities, utilizing existing burrows or excavating their own. These burrows provide shelter and protection from extreme temperatures and predators.

Mating occurs in the spring, followed by a gestation period of approximately 50 to 60 days. Female gopher snakes lay a clutch of eggs, typically ranging from six to 20 eggs, in warm and secluded locations. After an incubation period of around two months, the hatchlings emerge, ready to embark on their own journey.


Behavior of Gopher Snake Arizona

The Arizona gopher snake exhibits a range of behaviors that contribute to its survival and successful adaptation in the arid landscapes it inhabits. While these snakes are generally docile, they may display defensive behaviors when threatened.

When feeling threatened, gopher snakes often flatten their heads, hiss loudly, and mimic the rattling sound of rattlesnakes. This defensive strategy aims to intimidate potential predators and dissuade them from attacking. Additionally, they may vibrate their tails against dry leaves or grass, further enhancing their rattlesnake mimicry.

Gopher snakes are proficient climbers, utilizing their muscular bodies and specialized scales to ascend trees and cacti in search of prey or suitable basking spots. They are also adept at swimming, enabling them to cross water bodies and access new territories.

These snakes are primarily solitary, only coming together during the mating season. They rely on their keen senses, including vision and smell, to locate prey items such as rodents, lizards, birds, and eggs.

Diet of Gopher Snake Arizona

The diet of the Arizona gopher snake mainly consists of small mammals, particularly rodents like pocket gophers, mice, and rats. Their powerful constriction technique allows them to overpower their prey, squeezing until the prey is no longer able to breathe.

Gopher snakes are skilled hunters and possess an impressive ability to locate rodent burrows, utilizing their keen sense of smell. Once a prey item is located, however they seize it with their jaws and coil their bodies around it, initiating the constriction process. As the prey succumbs to the pressure, the snake slowly consumes it, headfirst.

These snakes are known to occasionally prey upon other reptiles, birds, and their eggs, expanding their diet to adapt to available food sources. This dietary versatility further contributes to their ecological importance in maintaining balanced ecosystems.

Life Span of Gopher Snake Arizona

The average lifespan of the Arizona gopher snake in the wild is approximately 12 to 15 years. However, some individuals have been reported to live for over 20 years. Factors such as habitat quality, availability of prey, and avoidance of predators contribute to their overall longevity.

Reproduction of Gopher Snake Arizona

Arizona gopher snakes engage in sexual reproduction, with males actively seeking out receptive females during the breeding season. Mating occurs in the spring, typically between March and May, when temperatures begin to rise.

Once mating is successful, the female undergoes a gestation period of around 50 to 60 days. During this time, she searches for a suitable location to lay her eggs, often selecting warm and secluded spots such as burrows or decaying vegetation.

The female gopher snake lays a clutch of eggs, typically ranging from six to 20 eggs, depending on various factors such as her size and age. She does not exhibit any further parental care, and the eggs are left to incubate independently.

After approximately two months of incubation, the hatchlings emerge from their eggs. These juveniles are fully independent from birth and must navigate the challenges of their environment to survive and grow.

Relationship with Humans

The Arizona gopher snake has an intriguing relationship with humans. Despite its resemblance to venomous rattlesnakes, it plays a crucial role in controlling rodent populations, making it beneficial in agricultural and residential areas.

Unfortunately, misunderstanding and fear often lead to unnecessary persecution of these harmless snakes. Educating the public about their beneficial attributes and unique behaviors is essential to fostering a coexistence between humans and gopher snakes.

Predators of Gopher Snake Arizona

While gopher snakes have evolved effective defense mechanisms, they still face predation from various species. Natural predators of the Arizona gopher snake include larger snakes such as kingsnakes and coachwhips. Additionally, birds of prey, including hawks and owls, pose a threat to both juveniles and adults.

The mimicry displayed by gopher snakes helps deter potential predators, as their resemblance to venomous rattlesnakes creates an illusion of danger. By imitating rattlesnake behavior, these non-venomous snakes reduce their risk of predation.


The Arizona gopher snake, with its captivating appearance and unique behaviors, adds to the rich biodiversity of the southwestern United States. As a non-venomous constrictor, it plays a vital ecological role in controlling rodent populations, contributing to the delicate balance of the arid ecosystems it inhabits.

Despite its resemblance to rattlesnakes, the Arizona gopher snake poses no threat to humans and should be appreciated for its beneficial attributes. However education and awareness are key to dispelling misconceptions and fostering a harmonious coexistence between humans and this intriguing species.

Through its mimicry and adaptations, the Arizona gopher snake showcases the wonders of nature’s evolutionary processes. Its ability to thrive in arid habitats, utilize various defense mechanisms, and adapt its diet exemplify the species’ resilience and versatility.
