Lemming
Lemmings are small rodents in the subfamily Arvicolinae, found in northern parts of North America, Europe, and Asia, especially Arctic and subarctic habitats.
Lemmings are small rodents in the subfamily Arvicolinae, found in northern parts of North America, Europe, and Asia, especially Arctic and subarctic habitats. They are known for population cycles and occasional large migrations, which have contributed to popular myths about mass suicide that are not true.
Classification and species
Lemmings are rodents in the subfamily Arvicolinae, alongside voles and muskrats. Sources describe about 20 species, with genera including Lemmus, Dicrostonyx, Myopus, and Synaptomys.
Habitat and range
Lemmings live in northern environments such as Arctic tundra, taiga, and other cold habitats across North America, Europe, and Asia. They are adapted to cold conditions with thick fur and burrowing behavior.
Diet and behaviour
Lemmings are mainly herbivores, feeding on grasses, mosses, roots, sedges, and related vegetation. Their populations can fluctuate dramatically, and some species migrate when food availability or population density changes.
Cultural myths
Lemmings are widely associated with the false claim that they commit mass suicide by running off cliffs or into the sea. Britannica Kids states this is untrue; lemmings generally try to avoid water, though accidental drowning can occur during movement or migration.
Key facts
- Lemmings are small northern rodents with thick fur, short tails, and small ears.
- They are found only in the Northern Hemisphere, mainly in Arctic and subarctic regions.
- Their diet is mostly plant matter, including grasses, mosses, roots, and sedges.
- Population sizes can rise and fall sharply over time.
- The popular idea that lemmings deliberately jump off cliffs is a myth.
Lemmings are part of Canada’s Arctic and northern wildlife, with species present in northern regions of Canada. They are relevant to Canadian ecology because they are an important herbivore in tundra food webs. [2][3][11]
