Norway Brown Lemming

The Norway lemming, also known as the Norwegian lemming (Lemmus lemmus) is a common species of lemming found in northern Fennoscandia, where it is the only vertebrate species endemic to the region. The Norway lemming dwells in tundra and fells, and prefers to live near water. Adults feed primarily on sedges, grasses and moss. They are active at both day and night, alternating naps with periods of activity. == Distribution == It has a wide distribution from western Norway east to the Kola Peninsula. A 2021 study suggests that the lemmings of Novaya Zemlya may also belong to this species; this would extend its range east to Novaya Zemlya island, but these results have not been fully accepted. == Description == The mainland Norway lemming has a bold pattern of black and yellow-brown, which is variable between individuals. In contrast, the Novaya Zemlya lemming has a cryptic gray coloration (hence why it was previously thought to be a population of the Siberian brown lemming). The species grows to a size of 155 mm (6.1 in). The tail is very short 10–19 mm (3⁄8–3⁄4 in). It weighs up to 130 g (4.6 oz). The dental formula is 1/1, 0/0, 3/3. ==…
