mustelid
any of 54 species of ferrets, polecats, badgers, martens, otters, the wolverine, and other members of the weasel family. Historically, skunks have also been included in Mustelidae, but genetic analyses suggest that they belong to a separate family of their own (Mephitidae). Mustelids are fur-bearing carnivores that inhabit terrestrial and aquatic regions throughout the world, except Australia, Antarctica, and most oceanic islands. Many, such as the American mink (Mustela vison), are trapped or raised commercially for their pelts.
