American Mink (Neovison vison) Scientific classification Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Carnivora Family: Mustelidae Genus: Neovison (Mustela) Species Neovison vison Neovison macrodon Mustela lutreola

European Mink, Mustela lutreola. There are two living species of "mink," the American Mink and the European Mink. The extinct Sea Mink is related to the American Mink, but is much larger. All three species of mink are dark-colored, semi-aquatic, carnivorous mammals of the family Mustelidae, which also includes the weasels and the otters. The American Mink is larger, and more adaptable than the European Mink. It is sometimes possible to distinguish the European and American species because the American Mink usually has no a large white patch on its upper lip, while the European Mink always has one. Any mink without such a patch can be identified with certainty as an American Mink, but an individual with such a patch, if encountered in continental Europe, cannot be certainly identified without looking at the skeleton. The American Mink's fur has been highly prized for its use in clothing, with hunting giving way to farming. Its treatment has also been a focus of animal welfare activism. American Mink have found their way into the wild in Europe (including Great Britain) and South America, after being released from mink farms by animal rights activists or otherwise escaped from captivity. They are believed by some to have contributed to the decline of the less hardy European Mink through competition (though not through hybridization -- native European mink are in fact closer kin to European Polecats than to their North American cousins).[1] Trapping is used to control or eliminate feral American Mink populations.[citation needed] Mink oil is used in some medical products and cosmetics, as well as to treat, preserve and waterproof leather.
