The Great Basin Gopher Snake (Pituophis catenifer deserticola) is a species of small colubrid snake native to the western part of the United States. The Great Basin Gopher Snake can be found all over the west including some areas of Canada and Mexico. This serpent can be found in California, New Mexico, Oregon, Arizona, British Columbia, Washington, Wyoming, Nevada, Colorado, and Idaho.
The Great Basin Gopher Snake have dorsal spots that are dark brown or black, and they are connected to each other by very narrow lines that run along each side of the anterior end. On each side of the neck there usually is a dark longitudinal stripe that is surrounded by some lighter coloring, which eventually breaks up towards the posterior end of the snake and turns into dashes or small spots. The body scales are keeled and the head has a pointed shape. The Great Basin's underbelly has a creamy color with small, dark, irregular blotches. Their average lifespan is 7 years.

As aforementioned, the Great Basin Gopher Snake can be found all over the western United States. They can be found in many grasslands, woodlands, deserts, coastal sage scrub, agriculture land, and riparian areas.
The Great Basin is a great climber, swimmer, and burrower. It is one of the most commonly found snakes while hiking and driving on the road. They are easily seen in the Spring when the males are out and about trying to find a mate. The hatchlings are easily found in late August and September when they emerge from their eggs. Great Basins are not dangerous unless provoked, as is with most animals. When they are defending themselves from predators will elevate and inflate their bodies, and flatten its head into a triangular shape. Loud hissing noises will ensue, along with quick shaking of its tail to mimmick the sound of the deadly rattlesnake. Unlike the rattlesnake, however, the Great Basin is nonvenomous.
When it comes to subspecies of Gopher Snakes their eggs are laid anywhere from June to August, and the Great Basin is no exception. It usually takes the eggs 2 to 2.5 months to hatch. After the snakes mate in the Spring they usually lay anywhere from 3 to 24 eggs, with 7 eggs being the average. When the young are born, they are usually in the range of 12 to 18 inches in length.
