The Panamint kangaroo rat (''Dipodomys panamintinus'') is a species of rodent in the family Heteromyidae. It is endemic to the Mojave Desert in eastern California and western Nevada, in the United States.〔 ==Description== The Panamint kangaroo rat is considered medium-sized for its genus. It is pale clay-colored with blackish patches around the face. The tail is extremely long, on average 140% of its body length and contains a white stripe with a heavy tuft of hair at the end. The species is named after an area of its range in the Panamint Valley and Panamint Range Mountains just west of Death Valley. Their common name derives from their bipedal form. They morphologically adapted to use bipedal hopping as their primary means of locomotion. 〔 The Panamint kangaroo rat can be distinguished from other species of the genus because the hind feet have five toes which varies in comparison to other members which have four toes on their hind feet. Sexual dimorphism is present where males tend to be larger than females in body size. 〔 A notable characteristic of the Panamint kangaroo rat is the fur lined cheek pouches that it uses to obtain large quantities of food. These pouches keep the food separate from the mouth which aids in preventing moisture loss. 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Panamint kangaroo rat」の詳細全文を読む スポンサード リンク
