It is hard to guess what a Northern bog lemming weights. But we have the answer:
An adult Northern bog lemming (Synaptomys borealis) on average weights 21 grams (0.05 lbs).
The Northern bog lemming is from the family Muridae (genus: Synaptomys). When reaching adult age, they grow up to 8.3 cm (0′ 4″). Usually, Northern bog 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 bog lemming (Synaptomys borealis) is a small North American lemming. This is one of two species in genus Synaptomys, the other being the southern bog lemming.They have cylindrical bodies covered with long grey or brown fur with pale grey underparts. A patch of rust-coloured hair is seen at the base of the ears. They have small eyes, a hairy snout, and a short tail. They have 16 teeth and their upper incisors are grooved. They are 13 cm long with a 2-cm tail, and weigh about 30 g.These animals are found in wet northern forests, bogs, tundra, and meadows in Canada, Alaska, northern Washington, and New England. They feed on grasses, sedges, other green vegetation, and mosses, as well as snails and slugs. Their droppings are green. Predators include owls, hawks, mustelids, and snakes.Female lemmings have two or three litters of four to six young in a year. The young are born in a nest in a burrow or concealed in vegetation.They are active year-round, day and night. They make runways through the surface vegetation, and also dig burrows. They burrow under the snow in winter. These animals are often found in small colonies. Lemming populations go through a 3- or 4-year cycle of boom and bust.
