The Family Heteromyidae includes small to medium-sized rodents commonly known as kangaroo rats, kangaroo mice, and pocket mice, primarily found in North and Central America. These rodents are well adapted to arid and semi-arid environments, often exhibiting nocturnal behavior to avoid heat and predators. Heteromyids have large hind legs for jumping, fur-lined cheek pouches for carrying seeds, and efficient kidneys that conserve water. They are mostly granivorous, feeding on seeds, but may also eat vegetation or insects. By storing and dispersing seeds, members of Heteromyidae play an important role in desert ecosystem ecology.
