Pacific Gopher Snake (Pituophis catenifer ssp. catenifer) A poisonous snake can hurt you if you eat it.
A venomous snake can hurt you if it bites you. This snake species is totally harmless.
"Adults range in size from 3–7 feet. They are "active in the daytime, and at night in hot weather. They are 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. They are a good burrower, climber, and swimmer.
When threatened, a gopher snake will do several things, sometimes one after the other, including: crawling away quickly to escape or hide; freezing up - making the body rigid and kinked up so it won't be noticed or perceived as a snake; and striking at the threat to scare it off. Gophersnakes also use a more dramatic defensive behavior - sometimes a snake will elevate its body and inflate it with air while flattening its head into a triangular shape, hissing loudly, and quickly shaking its tail back and forth to make a buzzing sound."

Colubrid Snakes (Family Colubridae) Most colubrids are non-venomous, or have venom that is not known to be harmful to humans, and are mostly harmless. Some colubrids are described as opisthoglyphous "rear-fanged," meaning they have elongated, backward-facing grooved teeth in the back of their upper jaws.
