Stink badger

Stink badgers (Mydaus) are a genus of the skunk family of carnivorans, the Mephitidae. They resemble the better know members of family Mustelidae also termed 'badgers' (which are themselves a polyphyletic group). There are only two extant species - the Palawan stink badger (M. marchei), and the Sunda stink badger or Teledu (M. javanensis). They live only on western islands of the Malay Archipelago: Sumatra, Java, Borneo and (in the case of the Palawan stink badger) on the Philippine island of Palawan; as well as many other, smaller islands in the region.

Stink badgers are named for their resemblance to other badgers and for the foul-smelling secretions that they expel from anal glands in self-defense (which is stronger in the Sunda species).[3]

Stink badgers were traditionally thought to be related to Eurasian badgers in the subfamily Melinae of the weasel family of carnivorans (the Mustelidae), but recent DNA analysis indicates they share a more recent common ancestor with skunks, so experts have now placed them in the skunk family[3][4] (the Mephitidae, which is the sister group of a clade composed of Mustelidae and Procyonidae, with the red panda also assigned to one of the sister clades[5]). The two existing species are different enough from each other for the Palawan stink badger to be sometimes classified in its own genus, Suillotaxus.[3]

American hog-nosed skunk

The American hog-nosed skunk (Conepatus leuconotus) is a species of hog-nosed skunk from Central and North America, and is one of the largest skunks in the world, growing to lengths of up to 2.7 feet (82 cm). Recent work has concluded the western hog-nosed skunk (formerly Conepatus mesoleucus) is the same species, and Conepatus leuconotus is the correct name of the merged populations.In Texas, it is commonly known as the rooter skunk for its habit of rooting and overturning rocks and debris in search of food.

Badger

Badgers are short-legged omnivores in the families Mustelidae (which also includes the otters, polecats, weasels, and wolverines), and Mephitidae (which also includes the skunks). They are not a natural taxonomic grouping, but are united by possession of a squat body adapted for fossorial activity. All belong to the caniform suborder of carnivoran mammals. The 11 species of mustelid badgers are grouped in four subfamilies: Melinae (4 species, including the European badger), Helictidinae (5 species of ferret-badger), Mellivorinae (the honey badger or ratel), and Taxideinae (the American badger); the respective genera are Arctonyx, Meles, Melogale, Mellivora and Taxidea. Badgers include the most basal mustelids; the American badger is the most basal of all, followed successively by the ratel and Melinae; the estimated split dates are about 17.8, 15.5 and 14.8 million years ago, respectively. The two species of Asiatic stink badgers of the genus Mydaus were formerly included within Melinae (and thus Mustelidae), but more recent genetic evidence indicates these are actually members of the skunk family.Badger mandibular condyles connect to long cavities in their skulls, which gives resistance to jaw dislocation and increases their bite grip strength. This in turn limits jaw movement to hinging open and shut, or sliding from side to side, but it does not hamper the twisting movement possible for the jaws of most mammals.

Badgers have rather short, wide bodies, with short legs for digging. They have elongated, weasel-like heads with small ears. Their tails vary in length depending on species; the stink badger has a very short tail, while the ferret badger's tail can be 46–51 cm (18–20 in) long, depending on age. They have black faces with distinctive white markings, grey bodies with a light-coloured stripe from head to tail, and dark legs with light-coloured underbellies. They grow to around 90 cm (35 in) in length including tail.

The European badger is one of the largest; the American badger, the hog badger, and the honey badger are generally a little smaller and lighter. Stink badgers are smaller still, and ferret badgers smallest of all. They weigh around 9–11 kg (20–24 lb), with some Eurasian badgers around 18 kg (40 lb).

Eastern spotted skunk

The eastern spotted skunk (Spilogale putorius) is a small, relatively slender skunk found throughout the eastern United States and in small areas of Canada and Mexico.

This small skunk is more weasel-like in body shape than the more familiar striped skunk. The eastern spotted skunk has four stripes on its back which are broken in pattern, giving it a "spotted" appearance. They have a white spot on their forehead. They are found in Canada (southeast Manitoba and northwestern Ontario), the United States and northeastern Mexico. Males, at 46.3–68.8 cm (18.2–27.1 in) in total length, are large than females, at 35–54.4 cm (13.8–21.4 in). The tail accounts for roughly a third of their total length. Body mass can range from 0.2 to 1.8 kg (0.44 to 3.97 lb), with males averaging around 700 g (1.5 lb) against the female's average of 450 g (0.99 lb). Skull length is 43–55 mm (1.7–2.2 in). The Eastern spotted skunk is a very small skunk, which (for comparison sake) is no larger than a good-sized tree squirrel.They are much more active than any other type of skunk. They have mostly the same predators as any other skunk (big cats, bobcats, owls, humans, etc.). Up to eight skunks may share an underground den in the winter. They can also climb and take shelter in trees.Eastern spotted skunks seem to prefer forest edges and upland prairie grasslands, especially where rock outcrops and shrub clumps are present. In western counties, it relies heavily on riparian corridors where woody shrubs and woodland edges are present. Woody fencerows, odd areas, and abandoned farm buildings are also important habitat for Eastern Spotted Skunks.

Ferret-badger

Ferret-badgers are the five species of the genus Melogale, which is the only genus of the monotypic mustelid subfamily Helictidinae.

Bornean ferret-badger (Melogale everetti)

Chinese ferret-badger (Melogale moschata)

Javan ferret-badger (Melogale orientalis)

Burmese ferret-badger (Melogale personata)

Vietnam ferret-badger (Melogale cucphuongensis)

Hog-nosed skunk

The hog-nosed skunks belong to the genus Conepatus and are members of the family Mephitidae (skunks). They are native to the Americas. They have white backs and tails and black underparts.

Hooded skunk

The hooded skunk (Mephitis macroura) is a species of mammal in the family Mephitidae. Mephītis in Latin means "foul odor", μακρός (makrós) in Greek translates to "long" and οὐρά (ourá) translates to "tail".

Humboldt's hog-nosed skunk

Humboldt's hog-nosed skunk, also known as the Patagonian hog-nosed skunk (Conepatus humboldtii) is a type of hog-nosed skunk indigenous to the open grassy areas in the Patagonian regions of Argentina and Chile. It belongs to the order Carnivora and the family Mephitidae.

Lutrogale

Lutrogale is a genus of otters, with only one extant species—the smooth-coated otter.

Mephitidae

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.

There are twelve extant species of mephitids in four genera: Conepatus (hog-nosed skunks, four species); Mephitis (the hooded and striped skunks, two species); Mydaus (stink badgers, two species); and Spilogale (spotted skunks, four species). The two stink badgers in the genus Mydaus inhabit Indonesia and the Philippines; the other members of the family inhabit the Americas, ranging from Canada to central South America. All other mephitids are extinct, known through fossils, including those from Eurasia.Skunks were formerly classified as a subfamily of the Mustelidae (the weasel family); however, recent genetic evidence has 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. In alphabetical order, the living species of Mephitidae are:

Mephitis (genus)

The genus Mephitis is one of several genera of skunks, which has two species and a North American distribution.

Molina's hog-nosed skunk

Molina’s hog-nosed skunk, Conepatus chinga, is similar to the common skunk with scent glands used to spray an odorous liquid to offend potential predators. They have a resistance to pit viper venom, distinct thin white markings and a pink, hog-like, fleshy nose.

Nyctereutes

Nyctereutes is an Old World genus of the family Canidae, consisting of just one living species, the raccoon dog of East Asia. Nyctereutes appeared about 9.0 million years ago (Mya), with all but one species becoming extinct before the Pleistocene.

Native to East Asia, the raccoon dog has been intensively bred for fur in Europe and especially in Russia during the twentieth century. Specimens have escaped or have been introduced to increase production and formed populations in Eastern Europe. It is currently expanding rapidly in the rest of Europe, where its presence is undesirable because it is considered to be a harmful and invasive species.

Palawan stink badger

The Palawan stink badger (Mydaus marchei), or pantot, is a carnivoran of the western Philippines named for its resemblance to badgers, its powerful smell, and the largest island to which it is native, Palawan. Like all stink badgers, the Palawan stink badger was once thought to share a more recent common ancestor with badgers than with skunks. Recent genetic evidence, however, has led to their re-classification as one of the Mephitidae, the skunk family of mammals. It is the size of a large skunk or small badger, and uses its badger-like body to dig by night for invertebrates in open areas near patches of brush. While it lacks the whitish dorsal patches typical of its closest relatives, predators and hunters generally avoid the powerful noxious chemicals it can spray from the specialized anal glands characteristic of mephitids.

Pygmy spotted skunk

The pygmy spotted skunk (Spilogale pygmaea) is a species of mammal in the family Mephitidae. It is endemic to Mexico.

Spotted skunk

The genus Spilogale includes all skunks commonly known as spotted skunks and is composed of four extant species: S. gracilis, S. putorius, S. pygmaea, S. angustifrons.

Striped hog-nosed skunk

The striped hog-nosed skunk, Conepatus semistriatus, is a skunk species from Central and South America (from southern Mexico to northern Peru, and in the extreme east of Brazil). It lives in a wide range of habitats including dry forest scrub and occasionally, in rainforest.These white-backed skunks inhabit mainly the foothills and partly timbered or brushy sections of their general range. They usually avoid hot desert areas and heavy stands of timber. The largest populations occur in rocky, sparsely timbered areas.

It is a nocturnal solitary animal, feeding mainly on invertebrates, small vertebrates and fruits.

Sunda stink badger

The Sunda stink badger (Mydaus javanensis), also called the Javan stink badger, teledu, Malay stink badger, Malay badger, Indonesian stink badger and Sunda skunk, is a mammal native to Indonesia and Malaysia. Despite the common name, stink badgers are not closely related to true badgers, and are, instead, Old World relatives of the skunks.

Western spotted skunk

The western spotted skunk (Spilogale gracilis) is a spotted skunk of western North America
