Perognathus

	Perognathus ''Perognathus'' is a genus of pocket mouse. Like other members of their family they are more closely related to pocket gophers than to true mice. Characteristics The silky pocket mice are small animals with soft pelage, long tails, and small feet compared to other heteromyids. They have long claws which are used for digging burrows and sifting sandy substrates for seeds. They have also been found to steal seeds from kangaroo rats' dens. They store these seeds in large hairy external cheek pouches. They are nocturnal and are found in arid habitats. They are not true hibernators, but will go into torpor and stay in their burrows for extended periods of time.

	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 ...

	Perognathus Flavus The silky pocket mouse (''Perognathus flavus'') is a species of rodent in the family Heteromyidae. It is found in northern and central Mexico and the southwest region of the United States. It is a species of least concern, according to the IUCN, with no known major threats. The silky pocket mouse eats seeds, succulent parts of plants and nuts, and carries food in its cheek pouches. It lives in low valley bottoms with soft soils, among weeds and shrubs, where it burrows in the sand to bury seed caches. The species is more tolerant of harsh habitat conditions than other pocket mice. Description The silky pocket mouse is the smallest pocket mouse in the family Heteromyidae, though otherwise is very similar in appearance to the other members of the genus ''Perognathus''. Its relatively short tail, which is buff or dusky colored above and white below, does not have a tuft of hair at the tip and is always shorter than the combined length of the head and body, which average about .

	Perognathus Alticola The white-eared pocket mouse (''Perognathus alticolus'') is a species of rodent in the family Heteromyidae. It is endemic to the San Bernardino Mountains and the Tehachapi Mountains of southern California in the United States. There are two subspecies of ''P. alticolus'' in California, ''P. a. alticolus'' and ''P. a. inexpectatus'', both of which are considered species of special concern by the California Department of Fish and Wildlife. Characteristics White-eared pocket mice are native to the San Bernardino Mountains and Tehachapi Mountains in California. They are named after there feature of having white or yellowish hair on the external portion of there ear. Within the genus Perognathus, ''P. alticolus'' is on the medium to large size.

	Perognathus Flavescens The plains pocket mouse (''Perognathus flavescens'') is a Heteromyidae, heteromyid rodent of North America.Monk, R. Richard, and J. Knox Jones.Perognathus flavescens" Mammalian Species 525 (1996): 1-4. It ranges from southwestern Minnesota and southeastern North Dakota to northern Texas east of the Rocky Mountains, Rockies, and from northern Utah and Colorado to northern Chihuahua (state), Chihuahua west of the Rockies. It has soft silky fur and grows to be long, although nearly half of that is the tail. They often live directly underneath Yucca faxoniana, Spanish bayonet or Opuntia, prickly pear plants. They are accustomed to sandy soil and eat mostly seeds, large and small grasses and small leaves of plants. Some food found in their cheek pouches are: seeds of needle grass (''Stipa''), bind weed, sandbur grass, a small bean (probably ''Astragalus''), and sedge (''Cyperus''). Even those caught in grain fields usually have their pouches filled with weed seeds. Seeds of two spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Perognathus Merriami Merriam's pocket mouse (''Perognathus merriami'') is a species of rodent in the family Heteromyidae. It is found in northeast Mexico and New Mexico, Oklahoma and Texas in the United States. Its habitat is shortgrass prairie, desert areas with scrub and arid shrubland. The species is named to honor Clinton Hart Merriam, a biologist who first described several other members of the genus ''Perognathus'', and first elucidated the principle of a "life zone" as a means of characterizing ecological areas with similar plant and animal communities. Description Merriam's pocket mouse is a small species with a smooth silky coat. Adults average in total length including a tail averaging but the size and shade vary across the animal's range. The general color is yellowish with a dark sheen caused by the longer guard hairs having black tips. The underparts, legs and feet are white or creamy in color, and the tail is paler on its undersurface. There are dark streaks on the side of the face an ...

	Perognathus Longimembris Pacificus The Pacific pocket mouse, ''Perognathus longimembris pacificus'', is endemic to California. It lives in sandy coastal soils of the coastal sage scrub ecoregion. It eats seeds and some insects. It was believed to be extinct until 1993, when a small population was discovered. It is now a federally listed Endangered animal species. Physical description As members of Heteromyidae—which consists of animals surviving on seeds and grain—Pacific pocket mice have fur-lined cheek pouches externally. Most of the body is covered in fur that feels silky. The coats are spineless and bristle free. The color of the Pacific pocket mouse is linked to the environment they live in, hence they are the color of the soil. The dorsal side of the pocket mouse is usually brown and pinkish while the ventral is usually white. There are typically two patches of hair that are lighter at the base of the ear, a distinguishing mark of the Pacific pocket mouse. The tail can either be distinctly or indistinctl ...

	Perognathus Longimembris The little pocket mouse (''Perognathus longimembris'') is a species of rodent in the family Heteromyidae. It is found in Baja California and Sonora in Mexico and in Arizona, California, Idaho, Nevada, Oregon and Utah in the United States. Its natural habitat is subtropical or tropical dry lowland grassland. It is a common species and faces no particular threats and the IUCN has listed it as being of "least concern". Five mice of this species travelled to and orbited the Moon 75 times in an experiment on board the Apollo 17 command module in December 1972. Four of the mice survived the trip. Six other little pocket mice were sent into orbit with Skylab 3 in July 1973, though these animals died only 30 hours into the mission due to a power failure. Behavior This small mouse, with a long tail, inhabits arid and semiarid habitats with grasses, sagebrush and other scrubby vegetation. It is nocturnal and has a short period of activity for the first two hours after sunset, and then sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Perognathus Inornatus The San Joaquin pocket mouse or Salinas pocket mouse (''Perognathus inornatus'') is a species of rodent in the family Heteromyidae. It is endemic to California in the United States where it lives in desert and semi-desert habitats. Description Pocket mice can be distinguished from similar small rodents by their externally opening fur-lined cheek pouches. They differ from kangaroo mice in not having the soles of the feet entirely covered in fur. Kangaroo rats have fur-lined pockets, but they are larger, and have a dark stripe across the hips and dark stripes on both the top and bottom surfaces of the tail. The San Joaquin pocket mouse has a total length of about , including a tail of . The tail has a short tuft of hairs at its tip. The fur on the head and body is short and soft, without spines or bristles. The colour is buff, and there is sometimes a pale patch at the base of the small rounded ears.
