Collared lemming
Genus of rodents
From Wikipedia, the free encyclopedia
Dicrostonyx is a genus of rodent in the family Cricetidae.[1] Its members are known as collared lemmings or varying lemmings. The genus is restricted to high latitudes in the northern hemisphere; one species, the Arctic lemming, has a broad distribution in northern Russia, while the rest are mostly or entirely North American in distribution. They are the only rodents that turn completely white in winter.[2]
