| The Mexican Spiny Pocket Mouse occurs in central and northeastern Mexico and the extreme south of Texas. It inhabits a variety of semi-arid brushy or rocky habitats, and is common where it lives. The "pockets" of the pocket Mouse are fur-lined cheek pouches, where seeds are carried from the foraging area to the burrow. Mexican Spiny Pocket Mice are grayish-brown, with white underparts. On the back, a mixture of stiff spiny hairs and soft ones gives the animal a somewhat coarse appearance. These Mice are nocturnal and are active year-round.
Males are larger than females.
238 mm males; 226 mm females
216-262 mm males; 207-251 mm females
40-60 g males; 35-50 g females
