Pituophis catenifer is a harmless colubrid species found in North America. Six subspecies are currently recognized, including the nominate subspecies described here. The specific name catenifer is Latin for 'chain bearing', referring to the dorsal color pattern.
Adults specimens are 36-84 inches (91–213 cm) in length. Dorsally they are yellowish or pale brown, with a series of large dark brown or black blotches, and smaller dark spots on the sides. Ventrally they are yellowish, either uniform or with brown markings.
The Gopher snake has an odd defense mechanism, in which it will puff it's body up and curl itself into the classic strike pose of the pit viper genus, but rather than an open mouthed strike, the gopher snake is known for striking with a closed mouth, using it's blunt nose to "warn-off" possible predators.
