The cheek pouch is a specific morphological feature that is evident in particular subgroups of rodents (e.g. Heteromyidae and Geomyidae, or gopher), yet a common misconception is that certain families, such as Muridae (including the common black and brown rats), contain this structure when in fact their cheeks are merely elastic due to a high ...
Gophers are burrowing rodents of the family Geomyidae, characterized by fur-lined, external cheek pouches used to gather and transport food. [41] The cheek pouches of geomyids such as the camas pocket gopher are controlled by a set of muscles, [ 42 ] with a sphincter controlling the opening and closing of the pouch.
The plains pocket gopher (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.
The neck is a little thinner but the heaviest part of the body is carried on the back of the head. The eyes are very small and beadlike and the ears are identified only by a meager flap of skin that follows the top of the temple. The cheek pouches are fur-lined and used for transporting food. The body gradually tapers from the head to the tail ...
They are larder hoarders, and their cheek pouches are used for transporting food back to their burrows. Gophers can collect large hoards. Unlike ground squirrels, gophers do not live in large communities and seldom find themselves above ground. Tunnel entrances can be identified by small piles of loose soil covering the opening. [11]
Perognathinae is a subfamily of rodents consisting of two genera of pocket mice.Most species live in complex burrows within the deserts and grasslands of western North America, They feed mostly on seeds and other plant parts, which they carry in their fur-lined cheek pouches [2] to their burrows.
The plains pocket mouse (Perognathus flavescens) is a heteromyid rodent of North America. [ 2 ] [ 3 ] It ranges from southwestern Minnesota and southeastern North Dakota to northern Texas east of the Rockies , and from northern Utah and Colorado to northern Chihuahua west of the Rockies.
Heteromyidae is a family of rodents consisting of kangaroo rats, kangaroo mice, pocket mice and spiny pocket mice.Most heteromyids live in complex burrows within the deserts and grasslands of western North America, though species within the genus Heteromys are also found in forests and their range extends as far south as northern South America.
