Lemming Lemming Lemming Lemming Magneet

A lemming is a small rodent, usually found in or near the Arctic in tundra biomes. Lemmings form the subfamily Arvicolinae (also known as Microtinae) together with voles and muskrats, which form part of the superfamily Muroidea, which also includes rats, mice, hamsters and gerbils. A longstanding myth claims that they exhibit herd mentality and jump off cliffs, committing mass suicide.
