List of mustelids

Six extant mustelid genera left-to-right, top-to-bottom: Martes, Meles, Lutra, Gulo, Mustela, and Mellivora

Mustelidae is a family of mammals in the order Carnivora, which includes weasels, badgers, otters, ferrets, martens, minks, and wolverines, and many other extant and extinct genera. A member of this family is called a mustelid; Mustelidae is the largest family in Carnivora, and its extant species are divided into eight subfamilies. They are found on all continents except Antarctica and Australia, and are a diverse family; sizes range, including tails, from the widespread 17 cm (7 in) least weasel to the 1.8-meter (6 ft) giant otter of Amazonian South America. Habitats vary widely as well, from the arboreal marten to the fossorial European badger to the marine sea otter. Population sizes are largely unknown, though two species, the sea mink and Japanese otter, were hunted to extinction in 1894 and 1979, respectively, and several other species are endangered. Some species have been domesticated, e.g. the ferret and some populations of the South American tayra. Mustelidae is one of the oldest families in Carnivora; early mustelids first appeared around 28–33 million years ago.^[1]

The 23 genera and 62 extant species of Mustelidae are split into 8 subfamilies: Guloninae, martens and wolverines; Helictidinae, ferret-badgers; Ictonychinae, African polecats and grisons; Lutrinae, otters; Melinae, Eurasian badgers; Mellivorinae, the honey badger; Mustelinae, weasels and minks; and Taxidiinae, the American badger. In addition to the extant subfamilies, Mustelidae includes three extinct subfamilies designated as Leptarctinae, Mustelavinae, and Oligobuninae. Extinct species have also been placed into all of the extant subfamilies besides Helictidinae, in both extant and extinct genera; around 200 extinct Mustelidae species have been found, as well as fossil genera not given a species name, though due to ongoing research and discoveries the exact number and categorization is not fixed.

IUCN Red List categories

Conservation status
EX	Extinct (2 species)
EW	Extinct in the wild (0 species)
CR	Critically Endangered (1 species)
EN	Endangered (7 species)
VU	Vulnerable (6 species)
NT	Near threatened (7 species)
LC	Least concern (39 species)
Other categories
DD	Data deficient (1 species)
NE	Not evaluated (1 species)

Conservation status codes listed follow the International Union for Conservation of Nature (IUCN) Red List of Threatened Species. Range maps are provided wherever possible; if a range map is not available, a description of the mustelid's range is provided. Ranges are based on the IUCN Red List for that species unless otherwise noted. All extinct species or subspecies listed alongside extant species went extinct after 1500 CE, and are indicated by a dagger symbol "†". Population figures are rounded to the nearest hundred.

Classification

The family Mustelidae consists of 62 extant species belonging to 23 genera and divided into hundreds of extant subspecies, as well the extinct sea mink and Japanese otter, which are the only mustelid species to become extinct since prehistoric times. This does not include hybrid species or extinct prehistoric species. Modern molecular studies indicate that the 23 genera can be grouped into 8 subfamilies. Some prior classification schemes divided the family solely between the aquatic otters and all other species.

Mustelids

The following classification is based on the taxonomy described by Mammal Species of the World (2005), with augmentation by generally accepted proposals made since using molecular phylogenetic analysis; this includes reclassifying Guloninae, Helictidinae, Ictonychinae, Melinae, Mellivorinae, and Taxidiinae as subfamilies rather than as part of a paraphyletic group with Mustelinae
