The giant kangaroo rat is the largest member of the family that includes kangaroo rats, kangaroo mice and pocket mice. Named for its unique two-footed hopping movements, the giant kangaroo rat lives in grassland areas generally along the western edge of California's San Joaquin Valley from Fresno County in the north to Kern County in the south and the Carrizo Plain and Cuyama Valley in San Luis Obispo County. 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.

Dipodomys

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. Merriam's kangaroo rats have an average total length of mm. The tail is rather long, about mm in length, with an end tassle. The body is covered with dusky stripes which run the length of the head and body. The skull is sciuromorphous with dramatically inflated auditory bullae. The face is covered with dark facial markings. The belly of Merriam's kangaroo rat bears white, silky pelage. The hind feet, bearing four toes, are very large, 39 mm , with hairy soles. These hairy soles aid the kangaroo rat in jumping through loose sand.

In contrast to larger members dipodomys the genus, dipodomys, desert kangaroo rats occur in areas that receive little precipitation. They are eaten in the greatest abundance in the winter months, while green vegetation is eaten most during the mid-summer months.

Kangaroo rats , small mostly nocturnal rodents of genus Dipodomys , are native to arid areas of western North America. The common name derives from their bipedal form. They hop in a manner similar to the much larger kangaroo , but developed this mode of locomotion independently , like several other clades of rodents e. Kangaroo rats are four or five-toed heteromyid rodents with big hind legs, small front legs, and relatively large heads.

Dipodomys deserti is adapted to live in the lowest, hottest, and most arid regions of North America Nader, The number of sand dunes may limit the distribution of D. In contrast to larger members of the genus, desert kangaroo rats occur in areas that receive little precipitation. To compensate for the extreme and prolonged aridity of the region, they are restricted to sand dunes, which harbor richer food sources.

December In Texas, males are fertile all year, with peak reproductive activity occurring between August and March. They consume a variety of foods, but most commonly eat the seeds of grasses and forbs, green vegetation, and dry vegetation. They are easily able to retrieve shallowly buried seeds.
