Description
Botta's Pocket Gopher has smooth short fur. There is considerable color variation - they can be pale grey, brown, tan to almost black. The underside is slightly paler. The body is stocky with short legs with long front claws. The eyes and ears are small and the tail is bare at the tip. Pocket gophers have fur-lined external cheek pouches that are used for transporting food. The gopher can close its mouth behind its front teeth, so it can dig without getting dirt in its mouth.
