yleinenLemmuus

Yleinen Lemmuus is a Finnish word that translates to "common lemming" in English. The term is used to describe the common lemming (Dicrostonyx groenlandicus), a small rodent that is native to the Arctic regions of North America, Greenland, and Eurasia.

Physical Characteristics

The common lemming is a small rodent that is typically brown or reddish-brown in color, with a stocky build and relatively short legs. It has a short, rounded snout and a pair of small ears. Adult common lemmings typically weigh between 60-120 grams and are around 17-20 centimeters in length.

Habitat and Behavior

Common lemmings are found in a variety of habitats, including tundra, grasslands, and wetlands. They are herbivores and feed on a wide range of vegetation, including grasses, mosses, and lichens. They are social animals and are often found in large groups. During the summer months, common lemmings are active during the day, while in the winter months, they are primarily nocturnal.

Behavior During Migration

One of the most interesting aspects of the common lemming is its behavior during migration. Large groups of lemmings are known to migrate across the landscape, often in a dense and chaotic manner. This behavior has led to widespread misconceptions about the common lemming, with some claiming that the animals engage in collective suicide or mass hysteria. However, it is now believed that this phenomenon is more related to the lemmings' natural behavior, searching for food and escaping predators.
