Chaetodipus
''Chaetodipus'' is a genus of pocket mouse containing 17 species endemic to the United States and Mexico. Like other members of their family such as pocket mice in the genus ''Perognathus'', they are more closely related to pocket gophers than to true mice. Characteristics Members of this genus range in size from 80 to 125 mm (head and body) and weigh 15–47 grams (Nowak, 1999). Unlike the silky pocket mice (genus ''Perognathus''), most species of the genus ''Chaetodipus'' have harsh pelage with some bordering on spiny hair. They tend to be found in arid habitats where they feed on seeds, vegetation, and insects (Nowak, 1999). Females give birth to a litter of 2–9 young after a gestation period of just under a month. The longest recorded life span is 8 years and 4 months (Nowak, 1999). Species *'' Chaetodipus arenarius'' – Little desert pocket mouse *'' Chaetodipus artus'' – Narrow-skulled pocket mouse *'' Chaetodipus baileyi'' – Bailey's pocket mouse *'' Ch ...

Perognathinae
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 to their burrows. Description There are about twenty-six members of the subfamily Perognathinae divided among two genera. They are all small rodents. Adaptations include partially fused vertebrae in the neck, short fore limbs and much enlarged bullae (bubble-shaped bones in the skull). The dental formula is 1/1, 0/0, 1/1, 3/3 making twenty teeth in total. The molars have two-lobed cusps. The upper incisors are grooved and the enamel on the molars is quickly worn away by chewing leaving the dentine exposed. The check teeth have roots. Fur-lined cheek pouches are a feature across the family Heteromyidae. They have openings near the mouth and extend backwards along the sides of the neck. The fur on the animal ...

Heteromyidae
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 down as far as northern South America. They feed mostly on seeds and other plant parts, which they carry in their fur-lined cheek pouches to their burrows. Although they are very different in physical appearance, the closest relatives of the heteromyids are pocket gophers in the family Geomyidae. Description There are about fifty-nine members of the family Heteromyidae divided among six genera. They are all small rodents, the largest being the giant kangaroo rat (''Dipodomys ingens'') with a body length of and a tail a little longer than this. In many species the tail is tufted and is mainly used for balance. Other adaptations include partially fused vertebrae in the neck ...
