Maned wolf
Tall, solitary South American canine with a distinctive mane.
The maned wolf (Chrysocyon brachyurus) is a large canine of South America, found in Argentina, Brazil, Bolivia, Peru, and Paraguay, and almost locally extinct in Uruguay. It is the only species in the genus Chrysocyon, from Greek for 'golden dog,' and is neither a fox nor a wolf, despite its markings resembling those of a red fox. It is the largest canine in South America, weighing 20–30 kg and standing up to 110 cm at the withers, with slender legs and a dense reddish coat. Its young pups have darker fur than the bronze coat of adults. The maned wolf is a solitary, crepuscular, and omnivorous animal adapted to the open savanna environments of the South American Cerrado. It plays an important ecological role in seed dispersal, particularly of the wolf apple. Communication is primarily through scent marking, but it also produces a distinctive loud call known as a roar-bark. The species lives in open and semi-open habitats, especially grasslands with scattered bushes and trees, across south, central-west, and southeastern Brazil, Paraguay, northern Argentina, Bolivia east and north of the Andes, and far southeastern Peru. It is very rare in Uruguay, possibly displaced by habitat loss. The International Union for Conservation of Nature lists it as near threatened, and it is considered vulnerable by the Brazilian Institute of Environment and Renewable Natural Resources. In 2011, a female maned wolf struck by a truck underwent stem cell treatment, the first recorded use of such therapy to heal injuries in a wild animal. The term "maned wolf" refers to the mane on its nape. Local names include *aguará guazú* (meaning "large fox" in Guarani) and *lobo-guará* in Portuguese. The maned wolf is not closely related to foxes, wolves, coyotes, or jackals; its closest living relative is the bush dog. Fossils from the Holocene and late Pleistocene have been found in the Brazilian Highlands. A 2015 study reported genetic signatures of population expansion followed by contraction during Pleistocene interglaciations about 24,000 years ago. The species was first described in 1815 by Johann Karl Wilhelm Illiger as *Canis brachyurus*, and the genus *Chrysocyon* was established by Charles Hamilton Smith in 1839.

Lore & Background
The maned wolf is the tallest wild canid, with long legs adapted for moving through the tall grasses of its South American savanna habitat. Its dense coat is reddish-brown to golden orange on the sides, with long black legs, a distinctive black mane on the nape, a white tuft at the tail tip, and a white patch under the throat. The mane is erectile and used to make the animal appear larger when threatened or aggressive. Although rare, melanistic (black) individuals exist; the first photographic record of one was captured by a camera trap in northern Minas Gerais, Brazil, in 2013. Pups have darker fur than the bronze-colored adults. The skull features reduced carnassials, small upper incisors, long canine teeth, and a prominent sagittal crest; it has 42 teeth. Its rhinarium extends to the upper lip, and its vibrissae are long. Footprints resemble those of a dog but are disproportionate. The species is the only member of the genus *Chrysocyon*, meaning "golden dog," and is not a fox, wolf, coyote, or jackal. Its closest living relative is the bush dog. Fossils from the late Pleistocene and Holocene have been found only in the Brazilian Highlands, suggesting it evolved there. The maned wolf is found in Argentina, Brazil, Bolivia, Peru, and Paraguay, and is nearly extinct in Uruguay. It inhabits open and semi-open habitats, especially grasslands with scattered bushes and trees, such as the Cerrado. It is listed as near threatened by the IUCN and as vulnerable by the Brazilian Institute of Environment and Renewable Natural Resources.
Reader's Guide
The maned wolf is the only surviving large South American canid from the late Pleistocene extinction, with its closest living relative being the bush dog. It is a solitary animal that does not form packs, unlike most large canids. Its long legs are an adaptation to the tall grasslands of its native open and semi-open habitats, such as the Cerrado of Brazil, Paraguay, northern Argentina, Bolivia, and far southeastern Peru. The species communicates primarily through scent marking, and its distinctive call is known as a "roar-bark". It is an omnivore and plays an important ecological role in seed dispersal, particularly of the wolf apple. The maned wolf is listed as near threatened by the IUCN and vulnerable in Brazil, with habitat loss being a major threat, especially in Uruguay where it is almost locally extinct. Its evolutionary uniqueness is underscored by DNA evidence showing that the extinct genus *Dusicyon* (including the Falkland Islands wolf) was its closest historical relative, and that it shared a common ancestor with that genus about seven million years ago. In 2011, a female maned wolf injured by a vehicle became the first recorded wild animal to receive stem cell treatment for injury healing.

Frequently Asked Questions
Who is the Maned wolf?
The Maned wolf (Chrysocyon brachyurus) is a large, slender-legged canine native to South America, recognized by its dense reddish coat and the dark mane running along its neck and shoulders. It is the only living member of the genus Chrysocyon, a name derived from Greek meaning 'golden dog.'
Is the Maned wolf actually a wolf or a fox?
Despite its fox-like markings, the Maned wolf belongs to neither the fox nor the wolf lineage; it sits in its own monotypic genus, Chrysocyon, within the family Canidae. Its closest relatives are debated, but it is genetically distinct from both Vulpes and Canis species.
What are the Maned wolf's key physical traits?
Standing up to 110 cm at the withers and weighing 20–30 kg, it is the tallest wild canid in South America, supported by notably long, slender legs. Its body is covered in a thick reddish-brown coat, and it is the largest member of the South American canid community.
Where does the Maned wolf live and what is its conservation status?
Its range spans Argentina, Brazil, Bolivia, Peru, and Paraguay, though it has become nearly locally extinct in Uruguay. The IUCN lists it as Near Threatened, while Brazil's IBAMA classifies it as Vulnerable, reflecting ongoing pressure from habitat loss and road mortality.
What role does the Maned wolf play in its ecosystem?
As a solitary, crepuscular omnivore, it forages for small mammals, insects, and fruit across open grasslands and scrubland. It is a critical seed disperser for the wolf apple (Cynophalla flexuosa), often carrying seeds far from the parent plant and aiding regeneration of native vegetation.
