Rodent
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/richochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and pikas, whose i ...

Cricetidae
The Cricetidae are a family of rodents in the large and complex superfamily Muroidea. It includes true hamsters, voles, lemmings, muskrats, and New World rats and mice. At almost 608 species, it is the second-largest family of mammals, and has members throughout the Americas, Europe and Asia. Characteristics The cricetids are small mammals, ranging from just in length and in weight in the New World pygmy mouse up to and in the muskrat. The length of their tails varies greatly in relation to their bodies, and they may be either furred or sparsely haired. The fur of most species is brownish in colour, often with a white underbelly, but many other patterns exist, especially in the cricetine and arvicoline subfamilies. Like the Old World mice, cricetids are adapted to a wide range of habitats, from the high Arctic to tropical rainforests and hot deserts. Some are arboreal, with long balancing tails and other adaptations for climbing, while others are semiaquatic, with w ...

Narrow-headed Vole
The narrow-headed vole (''Microtus gregalis'') is a species of rodent in the family Cricetidae. Ranging over northern and central Asia and also into Alaska, it is the only species in the subgenus ''Stenocranius''. Description The narrow-headed vole has a head-and-body length between and a short tail of . The dimensions of the skull distinguishes it from other ''Microtus'' species in China. In summer, the fur on the back is pale yellowish-buff, paler on the flanks and merging into the yellowish-grey underparts. In winter, the dorsal colour is a brighter reddish-ochre. The tail can either be a uniform yellowish-buff or can be bicoloured, dark brown above and yellowish-brown below. The upper surfaces of the hands and feet are brownish-white. Distribution and habitat The narrow-headed vole is distributed across the tundra region of northern Asia from the White Sea to the Kolyma River. It also occurs as separate populations on the steppes of Kazakhstan, Kyrgyzstan, southwestern ...
