The coyote is a canine native to North America. It is smaller than its close relative, the gray wolf, and slightly smaller than the closely related eastern wolf and red wolf. It fills much of the same ecological niche as the golden jackal does in Eurasia, though it is larger and more predatory, and is sometimes called the American jackal by zoologists. Other names for the species, largely historical, include prairie wolf and brush wolf.
The wolf, also known as the gray wolf, timber wolf, western wolf, and its other subspecies is a canine native to the wilderness and remote areas of Eurasia and North America. It is the largest extant member of its family, with males averaging 43–45 kg (95–99 lb) and females 36–38.5 kg (79–85 lb). Like the red wolf, it is distinguished from other Canis species by its larger size and less pointed features, particularly on the ears and muzzle. Its winter fur is long and bushy and predominantly a mottled gray in color, although nearly pure white, red, and brown to black also occur. Mammal Species of the World, a standard reference work in zoology, recognises 38 subspecies of C. lupus..
The red fox is the largest of the true foxes and one of the most widely distributed members of the order Carnivora, being present across the entire Northern Hemisphere from the Arctic Circle to North Africa, North America and Eurasia. It is listed as least concern by the IUCN. Its range has increased alongside human expansion, having been introduced to Australia, where it is considered harmful to native mammals and bird populations. Due to its presence in Australia, it is included among the list of the "world's 100 worst invasive species".
The fennec fox or fennec is a small nocturnal fox found in the Sahara of North Africa, the Sinai Peninsula, South West Israel and the Arabian desert. Its most distinctive feature is its unusually large ears, which also serve to dissipate heat. Its name comes from the Berber word (fanak), which means fox, and the species name zerda comes from the Greek word xeros which means dry, referring to the fox's habitat. The fennec is the smallest species of canid. Its coat, ears, and kidney functions have adapted to high-temperature, low-water, desert environments. Also, its hearing is sensitive enough to hear prey moving underground. It mainly eats insects, small mammals, and birds.
The Arctic fox, also known as the white fox, polar fox, or snow fox, is a small fox native to the Arctic regions of the Northern Hemisphere and common throughout the Arctic tundra biome. It is well adapted to living in cold environments, and is best known for its thick, warm fur that is also used as camouflage. On average, Arctic foxes only live 3–4 years in the wild. Its body length ranges from 46 to 68 cm, with a generally rounded body shape to minimize the escape of body heat.
The common raccoon dog, also called the Chinese or Asian raccoon dog to distinguish it from the Japanese raccoon dog, is a small, heavy-set, fox-like canid native to East Asia. Named for its raccoon-like face markings, it is most closely related to foxes. Common raccoon dogs feed on many animals and plant matter, and are unusual among canids for climbing trees and for hibernating in cold winters. They are widespread in their native range, and are invasive in Europe where they were introduced for the fur trade. The similar Japanese raccoon dog, native to Japan, is the only other living member of the genus Nyctereutes. Other names for the common raccoon dog include mangut, and neoguri.
The African wild dog, also known as the painted hunting dog, painted wolf, African hunting dog, Cape hunting dog or African painted dog, is a canid native to sub-Saharan Africa. It is the largest of its family in Africa, and the only extant member of the genus Lycaon, which is distinguished from Canis by dentition highly specialised for a hypercarnivorous diet, and a lack of dewclaws. It was classified as endangered by the IUCN in 2016, as it had disappeared from much of its original range. The 2016 population was estimated at roughly 39 subpopulations containing 6,600 adults, only 1,400 of which were reproductive. The decline of these populations is ongoing, due to habitat fragmentation, human persecution and disease outbreaks.
The dire wolf is an extinct species of the genus Canis. It is one of the most famous prehistoric carnivores in North America, along with its extinct competitor, the sabre-toothed cat Smilodon fatalis. The dire wolf lived in the Americas during the Late Pleistocene and Early Holocene epochs. The species was named in 1858, four years after the first specimen had been found. Two subspecies are recognized, these being Canis dirus guildayi and Canis dirus dirus. The dire wolf probably evolved from Armbruster's wolf in North America. The largest collection of its fossils has been obtained from the Rancho La Brea Tar Pits in Los Angeles.
Coywolf is an informal term for a canid hybrid descended from coyotes and gray wolves. All members of the genus Canis are genetically closely related because their chromosomes number 78, therefore they can interbreed. One genetic study indicates that these two species genetically diverged relatively recently. Genomic studies indicate that nearly all North American gray wolf populations possess some degree of admixture with coyotes following a geographic cline, with the lowest levels occurring in Alaska, and the highest in Ontario and Quebec, as well as Atlantic Canada.
The dhole is a canid native to Central, South and Southeast Asia. Other English names for the species include Asiatic wild dog, Indian wild dog, whistling dog, red dog, and mountain wolf. It is genetically close to species within the genus Canis, though its skull is convex rather than concave in profile, it lacks a third lower molar and the upper molars sport only a single cusp as opposed to two to four. During the Pleistocene, the dhole ranged throughout Asia, Europe and North America but became restricted to its historical range 12,000–18,000 years ago.
The golden jackal is a wolf-like canid that is native to Southeast Europe, Southwest Asia, South Asia, and regions of Southeast Asia. Compared with the Arabian wolf, which is the smallest of the gray wolves, the jackal is smaller and possesses shorter legs, a shorter tail, a more elongated torso, a less-prominent forehead, and a narrower and more pointed muzzle. The golden jackal's coat can vary in color from a pale creamy yellow in summer to a dark tawny beige in winter. It is listed as Least Concern on the IUCN Red List due to its widespread distribution and high density in areas with plenty of available food and optimum shelter.
The maned wolf is the largest canid of South America. Its markings resemble those of foxes, but it is not a fox, nor is it a wolf. It is the only species in the genus Chrysocyon.
The gray fox, or grey fox, is a omnivorous mammal of the family Canidae, widespread throughout North America and Central America. This species and its only congener, the diminutive Channel Island fox, are the only living members of the genus Urocyon, which is considered to be the most basal of the living canids. Though it was once the most common fox in the eastern United States, and still is found there, human advancement and deforestation allowed the red fox to become more dominant. The Pacific States still have the gray fox as a dominant. It is the only American canid that can climb trees. Its specific epithet cinereoargenteus means "ashen silver".
The African golden wolf, also known as the golden wolf or African wolf, is a canid native to north and northeastern Africa. The species is common in north-west and north-east Africa, occurring from Senegal to Egypt in the east, in a range including Morocco, Algeria, Tunisia and Libya in the north to Nigeria, Chad and Tanzania in the south. It is a desert-adapted canid, and is common in plains and steppe areas, including ones lacking abundant water. In the Atlas Mountains, the species has been sighted in elevations as high as 1,800 metres. It is primarily a predator, targeting invertebrates and mammals as large as gazelle fawns, though larger animals are sometimes taken. Other foodstuffs include animal carcasses, human refuse, and fruit. The African wolf is a monogamous and territorial animal, whose social structure includes yearling offspring remaining with the family to assist in raising their parents' younger pups.
The bush dog is a canid found in Central and South America. In spite of its extensive range, it is very rare in most areas except in Suriname, Guyana, and Peru; it was first identified by Peter Wilhelm Lund from fossils in Brazilian caves and was believed to be extinct. The bush dog is the only living species in the genus Speothos, and genetic evidence suggests that its closest living relative is the maned wolf of central South America or the African wild dog. The species is listed as Near Threatened by the IUCN.
