The plains pocket gopher or Geomys bursarius is one of 35 species of pocket gophers, so named in reference to their externally located, fur-lined cheek pouches. They are burrowing animals, found in grasslands and agricultural land across the Great Plains of North America, from Manitoba to Texas. Pocket gophers are the most highly fossorial rodents found in North America.

G. bursarius has short fur with brown to black coloration over the upper body and lighter brown or tan fur on the underparts. Whitish hairs cover the tops of the feet, while the short, tapered tail is nearly naked. Fossorial adaptations include small eyes, short, naked ears, and large fore feet with heavy claws. Zygomatic arches are widely flared, providing ample room for muscle attachment, although, unlike other pocket gophers, this species does not use the curved incisors to assist the feet in digging. The external cheek pouches, which distinguish this family from other mammals, can be turned inside-out for grooming purposes. They are used for carrying food up to 2.8 in. in length and have a forward opening.

Other adaptations to a fossorial lifestyle include a low resting metabolic rate of 0.946 ml and high conductance, a tolerance for low oxygen levels and high carbon dioxide levels, and a decreased water intake.

The gophers spend 72% of their time in their nests, coming above ground to search for food or mates, and for young animals to establish new burrows. Territorial and aggressive, especially in male-to-male interaction, these rodents appear to use their greatly increased sensitivity to soil vibration to maintain their solitary lifestyle. They rarely explore burrows inhabited by other gophers, although they sometimes investigate those that have been previously abandoned.
