| The Llano Pocket Gopher may, in fact, be the same species as Cratogeomys fumosus, the Smoky Pocket Gopher. Because pocket gophers live in small groups that are isolated from each other, and that may differ somewhat in appearance, it is especially hard to tease out their relationships. This is what taxonomists do, and it is an ongoing challenge, helped, now, by DNA studies.
Llano Pocket Gophers have soft, lax fur that - like the fur of all pocket gophers - can lie flat either forward or backward, making it easy for the animal to scurry head first or tail first through its tunnel system.
Head and Body: 140-260 mm; Tail: 60-125 mm
