Pocket gophers, commonly referred to as gophers, are burrowing rodents of the family Geomyidae. There are about 35 species, all endemic to North and Central America. They are commonly known for their extensive tunneling activities.
The name "pocket gopher" on its own may be used to refer to any of a number of genera within the family. These are the "true" gophers, but several ground squirrels in the distantly related family Sciuridae are often called gophers, as well. The origin of the word "gopher" is uncertain. French gaufre, meaning waffle, has been suggested, on account of the gopher's tunnels resembling the honeycomb-like pattern of holes in a waffle. Another suggestion is that the word is of Muskogean origin.
Gophers weigh around 0.5 lb (230 g), and are about 6–8 in (150–200 mm) in body length, with a tail 1–2 in (25–51 mm) long. A few species reach weights approaching 1 kg (2.2 lb). Within any species, the males are larger than the females and can be nearly double their weight.
Average lifespans are one to three years. The maximum lifespan for the pocket gopher is about five years. Some gophers, such as those in the genus Geomys, have lifespans that have been documented as up to seven years in the wild.
Most gophers have brown fur that often closely matches the color of the soil in which they live. Their most characteristic features are their large cheek pouches, from which the word "pocket" in their name derives. These pouches are fur-lined, can be turned inside out, and extend from the side of the mouth well back onto the shoulders. Gophers have small eyes and a short, hairy tail, which they use to feel around tunnels when they walk backwards.
