Jumping mouse

Zapodinae, the jumping mice, are a subfamily 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. There are five toes to all the feet, but the first in the fore-feet is rudimentary, and furnished with a flat nail. The tail makes up for 60% of its body length and is used to gain balance while bounding. The cheeks have pouches. The Sichuan jumping 'yeti' mouse (Eozapus setchuanus) from China can be identified by the ‘Y’ marking on its belly.
