Harmless Gopher Snakes are often mistaken for the more dangerous rattlesnakes and unnecessarily killed. It is easy to avoid this mistake by learning to tell the difference between the two families of snakes as shown in these signs. Unless you have experience handling venomous snakes, you should never handle a snake unless you are absolutely sure that it is not dangerous.

Description |
Nonvenomous |
| Considered harmless to humans. |
| Size |
| Adults of this species can be 2.5 - 7 feet long (76 - 213 cm.) Great Basin Gophersnakes have been recorded up to 6 feet (183 cm) and are most commonly under 5 ft. long (152 cm.) Hatchlings of P. catenifer are fairly long, generally around 15 inches in length (38 cm.) |
| Appearance |
| A large snake with heavily keeled scales, a narrow head that is slightly wider than the neck, and a protruding rostral scale on the tip of the snout. Ground color is cream to yellowish, with large brown, blackish, and reddish brown blotches along the back and smaller markings on the sides. Often the blotches form a dark band on the sides of the neck. The back of the neck is pale in the southern part of the range, but mottled with dark coloring in the northern part of the range. The underside is pale with some dark markings. |
| Behavior |
| Active in the daytime, and at night in hot weather, and especially at dusk and dawn. One of the most commonly seen snakes on roads and trails, especially in the spring when males are actively seeking a mate, and in the fall when hatchlings emerge. A good burrower, climber, and swimmer. A powerful constrictor; kills prey by suffocating them in body coils or by pressing the animal against the walls of their underground burrows. When threatened, a gophersnake willl sometimes inflate its body, flatten its head and produce a loud hiss, often while moving its tail back and forth quickly which may sound like a rattle if this is done in dry vegetation. You can listen to a recording of a gophersnake hissing here. |
| Diet |
| Small mammals, especially pocket gophers, birds and their eggs, and occasionally lizards and insects. |
| Reproduction |
| As with other subspecies, eggs are probably laid June - August, hatching in 2 to 2.5 months. |
| Range |
| Occurs in southeastern California north of approximately the Riverside county line through the Mojave Desert and east of the Sierra Nevada mountains. Ranges north through nevada, eastern Oregon and Washington into British Columbia. Also found in parts of Idaho, Utah, Wyoming, Colorado, Arizona, and new Mexico. There is a wide range of integration with P. c. catenifer in northeastern California and eastern Oregon. Also intergrades with P. c. annectans in the south. |
| Habitat |
| Found in a variety of habitats - grassland, coastal sage scrub, agricultural lands, riparian areas, woodlands, and desert, from sea level to the mountains. Especially common in coastal areas. |
| Taxonomic Notes |
| 8 subspecies of Pituophis catenifer are recognized - 2 occur in Baja California, and 6 occur in the United States. It has been proposed that the snakes from Baja California are a new species. 5 of these subspecies occur in California, with one endemic, and one that only occurs in California and Baja California. Gophersnakes are related to Ratsnakes and Kingsnakes, and they have been known to interbreed with these species. |
| Conservation Issues (Conservation Status) |
| A very common snake, but often mistaken for the similar rattlesnake and killed unnecessarily. Frequently killed by traffic when crossing roads. |
