The giant kangaroo rat is the largest member of the family that includes kangaroo rats, kangaroo mice and pocket mice.

They were listed as endangered in April The giant kangaroo rat has a large, flattened head and a short neck. Large, fur-lined cheek pouches are used to store and carry seeds found while foraging. Their tails are longer than their combined head and body length. The tails have a crest of long hairs, terminating in a large tuft. Their long, strong legs enable them to quickly hop away from predators such as snakes. The giant kangaroo rat faces several threats that have the potential to reduce populations. These threats include:. The giant kangaroo rat prefers annual grassland on gentle slopes with sandy soils. However, most remaining populations are on poorer, marginal habitats which include shrub communities on a variety of soil types and steeper slopes. Giant kangaroo rats develop burrow systems, called precincts, with one to five or more separate openings.

This type of male-male competition is usually associated with dipodomys males obtaining matings with more females than other males do, dipodomys. This may help to dry them off. The Annals and Magazine of Natural History.

Dipodomys merriami , Merriam's kangaroo rat, is a rodent found in the arid regions of the southwest United States and Mexico. Dipodomys merriami are sand-dwelling mammals that inhabit arid regions of the southwestern United States and Mexico. Habitat requirements of Merriam's kangaroo rats are less strict than most other species of kangaroo rats. They can live equally well in sandy soils, clays, gravels, and among rocks. Compared to other kangaroo rats, Dipodomys merriami inhabits harder, stonier soils.
