The Mustelidae are a diverse family of carnivorous mammals, including weasels, stoats, badgers, otters, 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.
Mephitidae is a family of mammals comprising the skunks and stink badgers. They are noted for the great development of their anal scent glands, which they use to deter predators. Skunks were formerly classified as a subfamily of the Mustelidae ; however, in the 1990s, genetic evidence caused skunks to be treated as a separate family. Similarly, the stink badgers had been classified with badgers, but genetic evidence shows they share a more recent common ancestor with skunks, so they are now included in the skunk family. A 2017 study using retroposon markers indicated that they are most closely related to the Ailuridae and Procyonidae.
Badgers are short-legged omnivores in the family Mustelidae. Badgers are a polyphyletic rather than a natural taxonomic grouping, being united by their squat bodies and adaptions for fossorial activity. All belong to the caniform suborder of carnivoran mammals.
The honey badger, also known as the ratel, is a mammal widely distributed in Africa, Southwest Asia, and the Indian subcontinent. Because of its wide range and occurrence in a variety of habitats, it is listed as Least Concern on the IUCN Red List.
Tarsiiformes are a group of primates that once ranged across Europe, northern Africa, Asia, and North America, but whose extant species are all found in the islands of Southeast Asia. Tarsiers are the only living members of the infraorder; other members of Tarsiidae include the extinct Tarsius eocaenus from the Eocene, and Tarsius thailandicus from the Miocene. Two extinct genera, Xanthorhysis and Afrotarsius, are considered to be close relatives of the living tarsiers, and are generally classified within Tarsiiformes, with the former grouped within family Tarsiidae, and the latter listed as incertae sedis (undefined). Omomyids are generally considered to be extinct relatives, or even ancestors, of the living tarsiers, and are often classified within Tarsiiformes.
Caniformia is a suborder within the order Carnivora consisting of "dog-like" carnivorans. They include dogs, bears, raccoons, and mustelids. The Pinnipedia are also assigned to this group. The center of diversification for the Caniformia is North America and northern Eurasia. Caniformia stands in contrast to the other suborder of Carnivora, the Feliformia, the center of diversification of which was in Africa and southern Asia.
Meles is a genus of badgers containing four living species known as Eurasian badgers, the Japanese badger, Asian badger, Caucasian badger and European badger. In an older categorization, they were seen as a single species with three subspecies. There are also several extinct members of the genus. They are members of the subfamily Melinae of the weasel family, Mustelidae.
Ekorus ekakeran is a large, extinct mustelid mammal. Fossils, including largely complete skeletons, are known from the late Miocene of Kenya.
A grison is any mustelid in the genus Galictis. Native to Central and South America, the genus contains two extant species: the greater grison, which is found widely in South America, through Central America to southern Mexico; and the lesser grison, which is restricted to the southern half of South America.
Potamotherium an extinct genus of caniform carnivoran from the Miocene epoch of France and Germany. It has historically been assigned to the family Mustelidae, but more recent studies suggest that it represents a primitive relative of pinnipeds
Ferret-badgers are the six species of the genus Melogale, which is the only genus of the monotypic mustelid subfamily Helictidinae.
Stink badgers or false badgers are the species of the genus Mydaus of the skunk family of carnivorans, the Mephitidae. They resemble the better-known members of the family Mustelidae also termed 'badgers'. There are only two extant species – the Palawan stink badger or pantot, and the Sunda stink badger or teledu. They live west of the Wallace Line; the Sunda species on islands of the Greater Sunda Islands, being Sumatra, Java, and Borneo; in Borneo the badger is found in Indonesia, Malaysia and Brunei. The Palawan species lives in the Philippine island of Palawan as well as the islands surrounding it.
Megalictis is an extinct genus of large predatory mustelids that existed in North America during the "cat gap" from the Late Arikareean (Ar4) in the Miocene epoch. It is thought to have resembled a huge, jaguar-sized ferret, weighing up to 60–100 kilograms (130–220 lb).
Oligobunis is an extinct genus of mustelids, which existed during the Miocene epoch.
Enhydriodon is an extinct genus of mustelids known from Africa, Pakistan, and India that lived from the late Miocene to the early Pleistocene. It contains nine confirmed species, two debated species, and at least a few other undescribed species from Africa. The genus belongs to the tribe Enhydriodontini in the otter subfamily Lutrinae. Enhydriodon means "otter tooth" in Ancient Greek and is a reference to its dentition rather than to the Enhydra genus, which includes the modern sea otter and its two prehistoric relatives.
Eomellivora is an extinct genus of prehistoric mustelids, closely related to the honey badger, known from Eurasia and North America, and tentatively Africa. It was one of the biggest mustelids ever known, bigger and more hypercarnivorous than the modern wolverine.
Mellivora benfieldi or Benfield's honey badger is an extinct species of mustelid from the Late Miocene and Early Pliocene of Africa and possibly Europe.
