Groups of lemmings walk on the same path only when reaching hindrances. Their orientation seems to be mainly visual. Information that came with the lemming picture Lemmings, family Cricetidae, are rodents that are closely related to voles and meadow mice. The animals live in open grasslands or tundras in north temperate or arctic regions. The fur is reddish or grayish brown above and lighter-colored below, and the tail is stubby.
Collared lemmings turn white during winter, an adaptation to their snowy environment.
The animals burrow to make underground nests, which they line with grass or moss. They eat grass, roots, sprouts, and other plant materials. The mating season lasts from spring to fall, and the female bears up to 9 young after a 20-day gestation period. The legend that lemmings deliberately join in a death march to the sea, where they drown, is untrue. Lemmings migrate periodically from their home area when their population begins to exceed the food supply.
