The Mustelidae are a diverse family of carnivoran mammals, including weasels, badgers, otters, polecats, martens, grisons, and wolverines. Otherwise known as mustelids, they form the largest family in the suborder Caniformia of the order Carnivora with about 66 to 70 species in nine subfamilies.
Weasels are mammals of the genus Mustela of the family Mustelidae. The genus Mustela includes the least weasels, polecats, stoats, ferrets, and European mink. Members of this genus are small, active predators, with long and slender bodies and short legs. The family Mustelidae, or mustelids, is often referred to as the "weasel family". In the UK, the term "weasel" usually refers to the smallest species, the least weasel (M. nivalis), the smallest carnivoran species.
The ferret is a small, domesticated species belonging to the family Mustelidae. The ferret is most likely a domesticated form of the wild European polecat, as evidenced by the ferret's ability to interbreed with European polecats and produce hybrid offspring. Physically, ferrets resemble other mustelids because of their long, slender bodies. Including their tail, the average length of a ferret is about 50 cm (20 in); they weigh between 0.7 and 2.0 kg ; and their fur can be black, brown, white, or a mixture of those colours. The species is sexually dimorphic, with males being considerably larger than females.
Mink are dark-colored, semiaquatic, carnivorous mammals of the genera Neogale and Mustela and part of the family Mustelidae, which also includes weasels, otters, and ferrets. There are two extant species referred to as "mink": the American mink and the European mink. The extinct sea mink was related to the American mink but was much larger.
The European polecat, also known as the common polecat, black polecat and forest polecat, is a mustelid species native to Europe, Western Asia and North Africa. It is of a generally dark brown colour, with a pale underbelly and a dark mask across the face. Occasionally, colour mutations including albinos, leucists, isabellinists, xanthochromists, amelanists, and erythrists occur. It has a shorter, more compact body than other Mustela species, a more powerfully built skull and dentition, is less agile, and is well known for having the characteristic ability to secrete a particularly foul-smelling liquid to mark its territory.
Fur farming is the practice of breeding or raising certain types of animals for their fur.
The long-tailed weasel, also known as the bridled weasel, masked ermine, or big stoat, is a species of weasel found in North, Central, and South America. It is distinct from the short-tailed weasel, also known as a "stoat", a close relation in the genus Mustela that originated in Eurasia and crossed into North America some half million years ago; the two species are visually similar, especially the black tail tip.
The American mink is a semiaquatic species of mustelid native to North America, though human introduction has expanded its range to many parts of Europe, Asia, and South America. Because of range expansion, the American mink is classed as a least-concern species by the IUCN. The American mink was formerly thought to be the only extant member of the genus Neovison following the extinction of the sea mink (N. macrodon), but recent studies, followed by taxonomic authorities, have reclassified it and the sea mink within the genus Neogale, which also contains a few New World weasel species. The American mink is a carnivore that feeds on rodents, fish, crustaceans, frogs, and birds. In its introduced range in Europe it has been classified as an invasive species linked to declines in European mink, Pyrenean desman, and water vole populations. It is the animal most frequently farmed for its fur, exceeding the silver fox, sable, marten, and skunk in economic importance.
The sea mink is a recently extinct species of mink that lived on the eastern coast of North America around the Gulf of Maine on the New England seaboard. It was most closely related to the American mink, with continuing debate about whether or not the sea mink should be considered a subspecies of the American mink or a species of its own. The main justification for a separate species designation is the size difference between the two minks, but other distinctions have been made, such as its redder fur. The only known remains are bone fragments unearthed in Native American shell middens. Its actual size is speculative, based largely on tooth remains.
The Amazon weasel, also known as the tropical weasel, is a species of New World weasel native to South America. It was first identified from a museum specimen mislabelled as coming from Africa, hence the scientific name.
Mustelinae is a subfamily of family Mustelidae, including weasels, ferrets, and minks.
The Colombian weasel, also known as Don Felipe's weasel, is a very rare species of New World weasel only known with certainty from the departments of Huila and Cauca in Colombia and nearby northern Ecuador. Both its scientific and alternative common name honours the mammalogist Philip "Don Felipe" Hershkovitz.
The mink industry in Denmark produced 40 percent of the world's pelts. Denmark used to be the largest producer of mink skins in the world. Ranked third in Denmark's agricultural export items of animal origin, fur and mink skins have a yearly export value of about €500 million. Kopenhagen Fur, located in Copenhagen, is the world's largest fur auction house; annually, it sells approximately 14 million Danish mink skins produced by 2,000 Danish fur farmers, and 7 million mink skins produced in other countries. Mink produced in Denmark was considered to be the finest in the world and is ranked by grade, with the best being Saga Royal, followed by Saga, Quality 1, and Quality 2.
Neogale is a genus of carnivorous, highly active small mammals belonging to the Mustelidae family. Neogale contains four species: the Amazon weasel, the long and short-tailed weasels, and the American mink. Native to the Americas, members of the genus can be found as far north as Alaska and as far south as Argentina and Bolivia. Across this distribution, they thrive in a range of habitats, from the deep-freezes of the Alaskan and Canadian boreal forests to the arid desert southwest, and from the humid tropics of Central and South America to the windswept foothills of the Andes and northern Patagonia.
The American ermine or American stoat is a species of mustelid native to most of North America. The specific epithet refers to Arctic explorer and naturalist John Richardson.
Polecats are mustelids in the genus Mustela. It includes four living species — the black-footed ferret or American polecat, the domestic ferret, the European polecat, and the steppe polecat. Polecats share the genus Mustela with members of the subgenera Lutreola and Mustela.
South American weasels are New World weasels endemic to South America. There are two extant species — the Amazon weasel and the Colombian weasel.
