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) but most of this subspecies are from 5 - 6 ft. (152 - 183 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 straw, light brown or tan, with large brown or reddish blotches or saddles along the back and smaller markings on the sides. The back of the neck is yellowish or tan with small black spots. The underside is cream to yellowish with dark spots. |
| 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, this snake willl sometimes inflate the body, and flatten the 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. |
| Diet |
| Small mammals, especially pocket gophers, birds and their eggs, and occasionally lizards and insects. |
| Reproduction |
| Eggs are laid June - August and hatch in 2 to 2.5 months. |
| Range |
| Occurs in southeast California, from the Imperial Valley north to roughly the San Bernardino County line, and east to the Colorado river. The range extends south into the northeast tip of Baja California, and east into Arizona and New Mexico, then south through West Texas and far into Mexico. |
| Habitat |
| Found in a variety of habitats - desert flats, agricultural land, riparian areas including below sea level in the Imperial Valley. |
| 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. |
