Zapodidae, the jumping mice, is a family of mouse-like rodents in North America and China. Although mouse-like in general appearance, these rodents are distinguished by their elongated hind limbs, and, typically, by the presence of four pairs of cheek-teeth in each jaw.
The Okanogan Valley jumping mouse (Zapus okanoganensis), which is restricted to the Okanogan Valley and the eastern slopes of the Cascade Range, was described in 2017. [3] Although it is definitely thought to be a distinct species, it has not yet been properly published and is thus considered a nomen nudum , and is tentatively classified in Z ...
The meadow jumping mouse (Zapus hudsonius) is the most widely distributed mouse in the family Zapodidae.Its range extends from the Atlantic coast in the east to the Great Plains west, and from the arctic tree lines in Canada and Alaska to the north, and Georgia, Alabama, Arizona, and New Mexico to the south.

The mouse is around nine inches long, 60% of which is the tail, [5] and can jump in bounds of four feet when threatened. It usually travels slowly. It swims and climbs grass stems. It has long hind legs and a long, slender, scaly tail that it uses to communicate by making drumming noises. It also communicates using clucks and chirps.
The genetic makeup of a given population of Pacific jumping mice depends on their mating system, characteristics of the species, demography, and dispersal. However the following three components seem to be important to the genetic health of the Pacific jumping mouse. [7] The first component is behavioral instigation of dispersal.
The woodland jumping mouse occurs throughout northeastern North America. [6]Populations are most dense in cool, moist boreal woodlands of spruce-fir and hemlock-hardwoods where streams flow from woods to meadows with bankside touch-me-nots and in situations where meadow and forest intermix and water and thick ground cover are available.
The western jumping mouse (Zapus princeps), is a species of rodent in the family Zapodidae. [2] It is found in Canada and the United States. [3]Western jumping mice evolved during the Pleistocene, possibly from the fossil species Zapus burti, which is known from the late Blancan.
A kangaroo mouse is either one of the two species of jumping mouse (genus Microdipodops) native to the deserts of the southwestern United States, predominantly found in the state of Nevada. The name "kangaroo mouse" refers to the species' extraordinary jumping ability, as well as its habit of bipedal locomotion. The two species are:
