What is a lemming?


After I posted the comment about the Miss Washington contestants being shuttled around like Lemmings I figured you might want to know more about lemmings.

From Wikipedia
Lemmings are small rodents, usually found in or near the Arctic, in tundra biomes. Together with the voles and muskrats, they make up the subfamily Arvicolinae (also known as Microtinae), which forms part of the largest mammal radiation by far, the superfamily Muroidea, which also includes the rats, mice, hamsters, and gerbils.
Lemmings weigh from 30 to 112 grams (1–4 oz) and are about 7 to 15 centimetres (2.75 – 6 in) long. They generally have long, soft fur and very short tails. They are herbivorous, feeding mostly on leaves and shoots, grasses, and sedges in particular, but also on roots and bulbs. Like many rodents' teeth, their incisors grow continuously, allowing them to exist on much tougher forage than would otherwise be possible.
Lemmings do not hibernate through the harsh northern winter. They remain active, finding food by burrowing through the snow and utilising grasses clipped and stored in advance.
