Lemmingidae

Lemmingidae is a family of small, herbivorous rodents belonging to the order Rodentia. These animals are typically found in the Arctic and alpine regions of the Northern Hemisphere. Lemmings are characterized by their short legs, stout bodies, and small, rounded ears. Their fur color varies depending on the species and season, often providing camouflage against their snowy or rocky environments.

There are several genera within the Lemmingidae family, including Lemmus, Dicrostonyx, and Synaptomys. These genera contain a number of distinct species, each adapted to specific habitats. Lemmings are primarily herbivores, feeding on grasses, sedges, mosses, and other vegetation. Their diet is crucial for their survival in harsh climates.

Lemming populations are known for their cyclical fluctuations, often characterized by dramatic increases followed by sharp declines. These population dynamics have historically led to myths and misconceptions, most famously the inaccurate belief that lemmings commit mass suicide by jumping off cliffs. In reality, population booms can lead to increased competition for resources, prompting some individuals to disperse and search for new territories, which can result in mortality. Lemmings play an important role in their ecosystems, serving as a food source for predators such as foxes, owls, and stoats.
