: In winter, they live in extensive tunnel systems beneath the snow, which provides insulation and protection from predators.

Lemmings are small, stocky rodents primarily found in the Arctic tundra and Northern Hemisphere. Belonging to the same subfamily as voles and muskrats, these resilient creatures are essential to the Arctic food web, supporting predators like the Arctic fox and snowy owl. Physical Characteristics and Habitat Lemmings

In reality, lemmings exhibit when their populations become too dense. During these migrations, they may attempt to swim across large bodies of water; while they are capable swimmers, many drown due to exhaustion or panic, which observers historically misinterpreted as intentional suicide.

Lemming populations are famous for their dramatic fluctuations, often peaking every 3 to 5 years. These "lemming years" are crucial for the Arctic environment: These "lemming years" are crucial for the Arctic
