It is hard to guess what a Northern collared lemming weights. But we have the answer:
An adult Northern collared lemming (Dicrostonyx rubricatus) on average weights 46 grams (0.1 lbs).
The Northern collared lemming is from the family Muridae (genus: Dicrostonyx). It is usually born with about 3 grams (0.01 lbs). When reaching adult age, they grow up to 11.7 cm (0′ 5″). Usually, Northern collared lemmings have 4 babies per litter.
As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.
The northern collared lemming or Nearctic collared lemming (Dicrostonyx groenlandicus), sometimes called the Peary Land collared lemming in Canada, is a small North American lemming. At one time, it was considered to be a subspecies of the Arctic lemming (Dicrostonyx torquatus). Some sources believe several other species of collared lemmings found in North America are actually subspecies of D. groenlandicus.It has a short chunky body covered with thick grey fur with a thin black stripe along its back and light grey underparts. It has small ears, short legs and a very short tail. It has a pale brown collar across its chest. In winter, its fur turns white (believed to be the only rodent to do so), and it has large digging claws on its front feet. It is 14 cm long with a 1.5 cm tail and weighs about 40 g.This animal is found in the tundra of northern Canada, Alaska and Greenland. It feeds on grasses, sedges and other green vegetation in summer, and twigs of willow, aspen and birches in winter. Predators include snowy owls, gulls, wolverines, the Arctic fox and the polar bear.Female lemmings have two or three litters of four to eight young in a year. The young are born in a nest in a burrow or concealed in vegetation.It is active year-round, day and night. It makes runways through the surface vegetation and also digs burrows above the permafrost. It burrows under the snow in winter. Lemming populations go through a three- or four-year cycle of boom and bust. When their population peaks, lemmings disperse from overcrowded areas.
