Weasel

For other uses, see (disambiguation)}}}.

Weasels are mammals in the genus Mustela of the Mustelidae family. Originally, the name "weasel" was applied to one species of the genus, the European form of the Least Weasel (Mustela nivalis). Early literary references to weasels, for example their common appearances in fables, refer to this species rather than to the genus as a whole.

Weasels vary in length from 15 to 35 centimeters (6 to 14 inches), and usually have a light brown upper coat, white belly and black fur at the tip of the tail; in many species, populations living at high latitudes moult to a white coat with black fur at the tip of the tail in winter. They have long slender bodies, which enable them to follow their prey into burrows. Their tails are typically almost as long as the rest of their bodies. As is typical of small carnivores, weasels have a reputation for cleverness and guile.

Most weasels feed on small mammals, and in former times were considered vermin since some species took poultry from farms, or rabbits from commercial warrens. Some species of weasel have been reported to perform a "hypnotic dance" in front of prey, which appears to mesmerize it. In folklore at least, this behavior is particularly associated with the stoat.

Of the 16 extant species currently classified in the genus Mustela, only 10 have "weasel" in their common name. Among those that do not are the stoat, the two species of mink, and the polecats or ferrets.

Popular culture references

In U.S. popular culture in particular, the term "weasel" is associated with devious characters. Many of these references are unclear about the fact that in US usage, "weasel" refers to a genus rather than a single species; for example, in Brian Jacques' Redwall series, weasels are one of the many villainous races, along with rats and ferrets - whereas biologically speaking ferrets are a species of weasel. Here everyday usage reflects the original European use of the word weasel for a single species. In the Dilbert cartoons, some of the most devious characters are portrayed as literal weasels or have weasel-like features. To add to the weasel's reputation for skullduggery, the phrase "Weasel words" can be applied to someone who speaks insincerely or deviously. Famously, elements of the US media described the declaration by France, Germany and Belgium against the 2003 invasion of Iraq as "The Axis Of Weasel," a parody of the so-called "Axis of Evil."

Alan Lloyd's novel [Kine] is a fictional war in the English countryside between weasels (Mustela nivalis) and the invasive species mink (Mustela vison), who are depicted as sadistic, voracious invaders, giants in comparison to the weasels. Kine in this context is an archaic word for weasel.
