Heteromyids are found in the western United States, southwestern Canada, Mexico, Central America, and northern South America.
Heteromyids live in deserts, dry grasslands, and, in a few cases, wet and dry tropical forests. Desert pocket mice and kangaroo rats like arid, dry, climates that contain sand, scrubs, sagebrush, grasses, and chaparral. Kangaroo mice prefer sandy habitats. In all cases, heteromyids like areas that contain many seeds.
Kangaroo rats are considered keystone species because their burrows provide habitat for a variety of plants and animals. A keystone species is a species that is important in maintaining the biodiversity, the variety of different animals and plants, of an area.

Pocket mice, kangaroo rats, and kangaroo mice, sometimes called heteromyids (members of the family Heteromyidae), are small- to medium-sized rodents with external, fur-lined cheek pouches. The pouches open in front of the mouth and go back along the shoulders. They have fairly large eyes and short, rounded ears. Pocket mice use all four feet while walking, while kangaroo rats and mice use only the…
Heteromyids eat mostly seeds, but also eat green vegetation and, in some species, insects. Desert species can go without water for long periods of time. They leave their burrows at night to dig through soil with their forelimbs to gather seeds into their cheek pouches. When pouches are full, they return to one of their caches (KASH-uhz), hidden supply areas, which are used throughout the animal&#x…
Heteromyids are nocturnal, active at night, rodents. Kangaroo rats and mice move about mostly by hopping on their hind limbs, while pocket mice use all four of their limbs in a walking motion. They have a very basic social structure, mostly living alone except for females and young. They do interact with nearby neighbors, which are often relatives. Most species burrow tunnel systems with multiple …
Four species of pocket mice, kangaroo rats, and kangaroo mice are listed by the World Conservation Union (IUCN) as Critically Endangered, facing an extremely high risk of extinction in the wild. One species is listed as Endangered, facing a very high risk of extinction in the wild, and one species is Vulnerable, facing a high risk of extinction. The IUCN also lists nine species as Near Threatened,…
Physical characteristics: San Joaquin (san-wah-KEEN) pocket mice are small sand-colored mice with soft coats, sparse darker back hairs, and yellowish undersides. They do not have spiny hairs that are often found on other pocket mice species. A line separates the lighter belly hairs from the darker back hairs. San Joaquin pocket mice have short ears that sometimes have a base patch of lighter hair.…
Physical characteristics: Giant kangaroo rats are the largest members of heteromyids. They have long and powerful hind limbs that are used for hopping, and small and relatively weak front limbs that are used for digging. These animals have very long tails that are used for balance. Their dark tail has white lines along either side. They have large eyes, small rounded ears, and a somewhat rounded b…
