Maned Wolf
The maned wolf is the largest canid in South America, instantly recognizable by its long black legs, reddish orange coat, and the dark mane of fur that rises along its neck and shoulders. It roams the open grasslands, savannas and scrublands of central Brazil, eastern Bolivia, Paraguay, northern Argentina and one corner of southeastern Peru. Despite its name and appearance, it is neither a wolf nor a fox but belongs to a genus all its own, Chrysocyon. It is active mainly at dawn and dusk and travels alone across territories that can stretch up to 30 square kilometers. Its diet is unusually varied for a canid, with roughly half of what it eats coming from plant matter. The fruit known as the wolf apple is a staple food and also plays a role in seed dispersal across the savanna. Habitat loss from agriculture and cattle ranching, combined with road collisions and fires, has placed this species on the IUCN Near Threatened list.
Maned wolf, fox or something else?
Neither. The maned wolf looks like a red fox that was stretched on stilts, and the name calls it a wolf, but it is not closely related to either. It is the only living species in the genus Chrysocyon, a branch that separated from the rest of the dog family several million years ago and survived the extinctions that wiped out most of South America's other large canids. Its nearest living relative is the bush dog, an animal it resembles in no way at all. The names people give it are just as varied: aguará guazú in Guaraní, which means big fox, lobo de crin in Spanish, lobo guará in Portuguese, and guará wolf or fox on stilts in English. None of them is zoologically accurate, and the Guaraní one is the oldest.
Habitat and distribution
Cerrado is the word most closely associated with the maned wolf. This vast tropical savanna of central Brazil is the heart of its range, a mosaic of open grasslands, scattered trees, and gallery forests that lines the rivers. The species also occurs in eastern Bolivia, across much of Paraguay, and in the northern provinces of Argentina. Peru holds the western tip of the range, a single population in the Pampas del Heath savanna of Madre de Dios. In Uruguay the species is listed by the IUCN as possibly extinct. It tends to avoid dense forest and prefers areas where visibility is good and prey is easy to locate. Elevations below 1,500 meters suit it well. As agricultural expansion converts cerrado into farmland and pasture, suitable habitat has become increasingly fragmented, pushing maned wolves into closer contact with human settlements and roads.
Diet
Few large carnivores rely on fruit as heavily as the maned wolf does. Studies consistently show that plant matter makes up roughly half of its diet, with the wolf apple, known in Portuguese as lobeira, being the single most important food source throughout the year. This tomato relative grows abundantly across the cerrado and is eaten in large quantities. Beyond fruit, the maned wolf hunts small mammals such as armadillos, rodents, and rabbits, as well as birds, reptiles, and insects. It uses its large ears to detect prey moving beneath the grass, then leaps to pin it down. Seasonal shifts in food availability mean that the balance between animal and plant foods changes across the year, but fruit never disappears entirely from its diet.
Behavior
Dawn and dusk are when the maned wolf comes alive. It spends the hottest hours of the day resting in dense vegetation and begins moving as the light fades, covering several kilometers each night in search of food. Adults live alone for most of the year, with mated pairs sharing an overlapping territory of up to 30 square kilometers but rarely traveling together outside the breeding season. They communicate through a loud, hoarse bark called a roar bark, which carries across open terrain and helps individuals stay aware of one another. Scent marking is equally important, with urine deposits placed at regular intervals along regular paths. Captive studies show that pairs remain bonded over multiple years, yet in the wild each animal functions largely as an independent unit.
Why maned wolf urine smells like cannabis
The maned wolf marks its territory with a urine so pungent that it has earned the animal the nickname skunk wolf. The smell is unmistakable to anyone who has been near one, because it is almost exactly the smell of cannabis. The chemistry explains it: maned wolf urine is loaded with pyrazines, the same class of aromatic compounds that give cannabis much of its odor, and they evaporate slowly enough to keep a scent post working for days. In 2006 police were called to Rotterdam Zoo after visitors reported someone smoking marijuana on the grounds; the source turned out to be the maned wolf enclosure. For the animal it is a message board rather than a joke: a solitary canid covering 30 square kilometers needs a way to tell a neighbor where the boundary is without meeting it.
Ecological role
Seed dispersal is where the maned wolf makes its greatest contribution to the cerrado. After eating wolf apples and other fruits, it deposits the seeds across wide areas through its droppings, often far from the parent plant. Research has shown that seeds passed through the digestive system of a maned wolf germinate at higher rates than those that fall directly to the ground, suggesting a close relationship built over a long period between this animal and its food plants. Beyond dispersal, the maned wolf helps regulate populations of small rodents and insects through predation. Because it occupies a broad niche, sitting somewhere between apex predator and frugivore, its presence supports the structure of an entire ecosystem. Losing it would have ripple effects that are difficult to predict.
Conservation
Classified as Near Threatened on the IUCN Red List, the maned wolf faces a combination of pressures that continue to grow. The cerrado is one of the most threatened biomes on Earth, with more than half of its original extent already converted to agriculture and pasture for cattle. Roads that cut through remaining habitat claim many lives each year through vehicle collisions. Wildfires, both natural and set deliberately to clear land, destroy food sources and force animals into unfamiliar terrain. Domestic dogs carry diseases such as canine distemper and parvovirus, which can spread to wild populations. Conservation efforts focus on protecting corridors between habitat patches, reducing road deaths through wildlife crossing infrastructure, and managing disease risks near rural communities. Breeding programs in zoos across South America and Europe provide an additional safety net.

Frequently Asked Questions
How many maned wolves are left?
The IUCN puts the world population at fewer than 17,000 mature individuals, and about 72 percent of the range lies in Brazil, so most of those animals are Brazilian. Outside Brazil the total is thought to be under 5,000, spread thinly across Bolivia, Paraguay, Argentina and one corner of Peru. The species is listed as Near Threatened rather than in a threatened category, mainly because the range is still enormous, close to five million square kilometers.
What are baby maned wolves like?
Pups are born after a gestation of about 65 days, usually two or three in a litter and occasionally up to five, timed to the southern summer between roughly June and September in the wild. They come out almost black, with short legs and dark fur that gives no hint of the adult, and the red coat and long legs only arrive over the following months. The mother feeds them regurgitated food once they stop nursing at around four months. In captivity the male helps raise them; in the wild he is rarely seen doing it.
Are maned wolves dangerous to humans?
No. There is no record of a maned wolf attacking a person. It is a shy, solitary animal that avoids people, hunts prey no bigger than a rabbit or an armadillo, and runs at the first sign of trouble. The danger runs the other way: vehicles kill a large number of them every year on roads through the cerrado, farmers occasionally shoot them over chickens, and diseases carried by domestic dogs are a serious threat. It is also not a pet, and keeping one is illegal across its range.
Where can you see a maned wolf in the wild?
Two places in Brazil are famous for it. Serra da Canastra National Park, in Minas Gerais, holds one of the densest populations and is the classic spot for a sighting at dawn or dusk. The other is the Caraça Sanctuary, a nineteenth century monastery in the same state where the priests began leaving meat on the church steps in 1982 to keep the wolves out of the rubbish; they still come most nights, and visitors watch from the terrace. Elsewhere the animal is present but thinly spread and hard to find.
What eats a maned wolf?
Very little. An adult stands nearly a meter at the shoulder and has almost no natural predators across most of its range; pumas and jaguars can take one where they overlap, and large birds of prey or feral dogs may take a pup. In practice the things that kill maned wolves are human: vehicles on the highways that cut through the cerrado, shooting near farms, fires set to clear land, and canine distemper and parvovirus picked up from domestic dogs on the edges of the savanna.
What does the maned wolf eat?
The maned wolf has a surprisingly varied diet. About half of what it eats comes from plants, and the wolf apple, a fruit that grows across the cerrado, is its most important food source. It also hunts small animals like rodents, armadillos, rabbits, birds, and insects. Very few large carnivores rely on fruit as heavily as this one does, which makes its diet quite unusual among animals of its size.
Where does the maned wolf live?
The maned wolf is found mainly in central South America. Brazil's cerrado is the core of its range, but it also lives in eastern Bolivia, much of Paraguay, and northern Argentina. Small populations exist at the edges of its range in Peru and Uruguay. It prefers open grasslands and savannas where it can spot prey easily, and it avoids dense forests. Most individuals live below 1,500 meters in elevation.
Is the maned wolf endangered?
The maned wolf is currently listed as Near Threatened on the IUCN Red List. It is not yet endangered, but the pressures it faces are serious and growing. More than half of the cerrado has already been converted to farmland and cattle pasture. Road collisions kill many individuals every year, and diseases carried by domestic dogs pose an additional risk. If habitat loss continues at its current pace, its status could worsen.
Why does the maned wolf have such long legs?
Those remarkable legs are an adaptation to life in tall grasslands. By standing higher off the ground, the maned wolf can see over the vegetation to spot prey or danger at a distance. The legs also help it move efficiently across open terrain. It is the tallest wild canid in the world, reaching about 90 centimeters at the shoulder, and those long limbs are a big part of what makes it so distinctive.
Does the maned wolf live alone or in groups?
Maned wolves are solitary animals. Each adult spends most of the year on its own, roaming a territory that can cover up to 30 square kilometers. Mated pairs share overlapping territories and stay bonded over multiple years, but they rarely travel together outside the breeding season. They keep in touch mainly through scent marks and a distinctive loud bark known as the roar bark, which carries far across open ground.
What is the wolf apple and why is it important?
The wolf apple, called lobeira in Portuguese, is a fruit in the tomato family that grows widely across the cerrado. It is the single most important food in the maned wolf's diet throughout the year. After eating the fruit, the wolf spreads the seeds across the savanna through its droppings, and research shows those seeds germinate at higher rates than seeds that fall directly to the ground. The two species depend on each other in a remarkable way.
