kangaroo rat
Kangaroo rats, small rodents of genus ''Dipodomys'', are native to western North America. The common name derives from their bipedal form. They hop in a manner similar to the much larger kangaroo, although they are not related.
==Description==
Kangaroo rats are four-toed heteromyid rodents with big hind legs, small front legs and relatively large heads. Adults typically weigh between 70 and 170 g.〔Nader, I.A. 1978. Kangaroo rate: Intraspecific Variation in Dipodomus spectabilis Merriami and Dipodomys deserti Stephens. Chicago, University of Illinois Press.〕 The tails of kangaroo rats are longer than both their bodies and their heads. Another notable feature of kangaroo rats are their fur-lined cheek pouches, which are used for storing food. The coloration of kangaroo rats varies from cinnamon buff to dark gray, depending on the species.〔Howard, V.W. 1994. ''Prevention and Control of Wildlife Damage''. S.E. Hygynstrom, R.M. Timm and G.E. Larson. New Mexico, (Cooperative Extension Division, Institute of Agriculture and Natural Resources, University of Nebraska- Lincoln, United States Department of Agriculture, Animal and Plant Health Inspection Service: Animal Damage Control, Great Plains Agricultural Council: Wildlife Committee). B101-B104.〕 There is also some variation in length with one of the largest species, the banner-tailed kangaroo rat being six inches in body length and a tail length of eight inches.〔 Sexual dimorphism exists in all species, with males being larger than females.
