Pituophis catenifer affinis, commonly known as the Sonoran gopher snake, is a nonvenomous subspecies of colubrid snake that is endemic to the southwestern United States. It is one of six recognized subspecies of the gopher snake, Pituophis catenifer . [5]

A baby Sonoran gopher snake in Sahuarita, Arizona.

It is found from central Texas across the Southwestern United States to southeastern California, Arizona, and south into the northern states of Mexico.

Description

Adults average 127–183 cm (4.17–6.00 ft) in total length. The maximum recorded total length is 234 cm (7.68 ft). [3]

The saddle-shaped dorsal blotches are reddish brown, [1] except for near and on the tail, where they are dark brown or blackish. [3]

The rostral is about as long as it is broad, not elongated as in other Pituophis subspecies. [6]

Habitat

It primarily inhabits the Sonoran Desert ecosystem of the Southwest USA, and into northern Mexico.

Diet

They feed on small rodents, hence the common name gopher snake.

Behavior

They are moderately defensive but can be tamed, and become very gentle. They have hard tough skin on their noses used to burrow into gopher holes and the burrows of other rodents. During the winter they brumate. They invade gopher holes and holes of other burrowing rodents and eat what they need to stay alive in the invaded burrow. When threatened by humans and farm equipment, these snakes are known to remain in harm’s way instead of making a retreat. These snakes will also tend to hiss and shake their tales when threatened which leads to them being confused with rattlesnakes and then killed due to this confusion.

Reproduction

P. c. affinis is oviparous. Adult females lay 7-22 eggs in July or August. The eggs average 51 mm × 35 mm (2.0 in × 1.4 in). The hatchlings are about 40 cm (15.5 in) in total length. [2]

Pituophis catenifer is a species of nonvenomous colubrid snake endemic to North America. Nine subspecies are currently recognized, including the nominotypical subspecies, Pituophis catenifer catenifer, described here. This snake is often mistaken for the prairie rattlesnake, but can be easily distinguished from a rattlesnake by the lack of black and white banding on its tail and by the shape of its head, which is narrower than a rattlesnake's.

<span class="mw-page-title-main">Cape gopher snake</span> Species of snake

The Cape gopher snake or Baja gopher snake is a species of nonvenomous colubrid snake endemic to extreme southern Baja California Sur, Mexico. They have become increasingly popular companions for people interested in the exotic pet trade, due to their extreme color variations and relatively docile behavior. It was previously considered to be a subspecies of Pituophis catenifer. There has been controversy whether the Baja Gopher Snake is a lower classification of the Cape Gopher Snake. Some say the Baja Gopher Snake should be in a separate sub-species of Pituophis Vertebralis Bimaris, while Cape Gopher Snakes should remain Pituophis Vertebralis Vertebralis. Many people mistake the two as the same sub species and have cased some cross-breeding between the two. In captivity the bloodlines are nearly all related and breeding has become especially difficult in terms of keeping the bloodlines alive.

<i>Pituophis melanoleucus</i> Species of snake

<span class="mw-page-title-main">Louisiana pine snake</span> Species of snake

The Louisiana pine snake is a species of large, non-venomous, constrictor in the family Colubridae. This powerful snake is notable because of its large eggs and small clutch sizes. The Louisiana pine snake is indigenous to west-central Louisiana and East Texas, where it relies strongly on Baird's pocket gophers for its burrow system and as a food source. The Louisiana pine snake is rarely seen in the wild, and is considered to be one of the rarest snakes in North America. The demise of the species is due to its low fecundity coupled with the extensive loss of suitable habitat - the longleaf pine savannas in the Gulf coastal plain of the southeastern United States. Management activities are being conducted to promote the species' recovery.

<span class="mw-page-title-main">Pacific gopher snake</span> Subspecies of snake

Pituophis catenifer catenifer is a subspecies of large non-venomous colubrid snake native to the western coast of North America. Pacific gopher snakes are one of California's most common snake species. They often get confused for rattlesnakes because they mimic similar patterns and defense mechanisms. As a result, gopher snakes can often avoid confrontation without needing to rely on their non-venomous nature for survival.
