The American mink, and its recently extinct cousin the sea mink (Neovison macrodon), have been considered the only “true” species of mink. The supposed European mink is actually a semi-aquatic polecat, being much closer related to the European polecat and Siberian weasel.(1)(2) The American mink was once considered a weasel of the genus Mustela, but in 1999 its Latin name was changed to Neovison.(3)


Introduced range and fur farming

The American mink is a semiaquatic species native to North America. Its fur has been highly prized for use in clothing, with hunting giving way to fur-farming. Their treatment on fur farms has been a focus of animal rights and animal welfare activism.(4) Between the 1920s and 1950s, American minks were imported to Europe, the USSR and southern South America for fur-farming. Today in parts of Europe, released or escaped American minks have been classified as an invasive species and linked to the decline of the European mink,(5)(6) as well as other small mammals and birds. Similar to the importation of stoats in New Zealand, it was human self-interest and irresponsibility that led to this ecological disruption, not the imported mink.

Colour mutations

Due to selective breeding, farm-bred American minks can range in colour from beiges, greys; to a brown that is almost black.(7) You’ll often see them portrayed as pure white in visual media, but this colour too is only created through selective breeding. A mink’s natural colour in the wild is brown. In the wild, their diet consists of rodents, fish, crustaceans, amphibians, and birds.(8)

Use in hunting

If properly trained, American minks make excellent hunting companions, as demonstrated by Joseph Carter ‘The Mink Man’ on his YouTube channel.
