The year is 2006, and police in Rotterdam, the Netherlands, receive an unusual report from the local zoo. Visitors and staff have apparently noticed the unmistakable smell of marijuana, so officers are called in to investigate.But when they arrive, there are no smokers to be found. Instead, after following the strange smell, they discover an animal that looks almost like a fox standing on stilts. The culprit is a maned wolf, and its unusual scent is coming from a rather unexpected source.Maned wolves are famous for the strong smell of their urine, which can be surprisingly similar to the smell of marijuana. The resemblance is so striking that it has reportedly caused confusion before, but the smell actually has nothing to do with drugs.Like many other canines, maned wolves rely heavily on scent to communicate, and urine marking helps them establish and recognize territories.That strange smell is only one of the many unusual things about this remarkable animal. From its incredibly long legs to its solitary lifestyle and bizarre sleeping patterns, almost everything about the maned wolf seems different from what you might expect from a wild canine.For humans, walking on stilts is mainly a form of entertainment. For maned wolves, however, those unusually long legs are a vital adaptation to their environment.These animals live primarily in open grasslands, where tall vegetation can make it difficult to see what is happening around them. Their long legs raise their heads above the grass and shrubs, giving them a better view while they search for food and watch for potential danger.Their height also makes it easier to move through tall vegetation. An adult can stand around 90 centimeters tall at the shoulder, making the maned wolf the tallest wild member of the canine family.Despite their impressive size, maned wolves are not built like typical predators. Their diet is surprisingly varied and includes animals such as rodents and armadillos, but plant food is also extremely important. Wild fruits, roots, and other vegetation can make up a substantial portion of what they eat.And despite being called a wolf, this strange creature is not actually a wolf at all.The maned wolf does not belong to the same group as wolves, foxes, coyotes, dogs, or jackals in the way its name might suggest. It is so unusual that it is the only living species in its genus, Chrysocyon, a name derived from Greek that can be translated roughly as “golden dog.”Its closest known relative is believed to have been another South American canid that eventually went extinct, leaving the maned wolf as a remarkably isolated branch of the canine family tree.Its unusual classification also fits its lifestyle. Unlike wolves, maned wolves do not live in packs or cooperate with groups of relatives to hunt. They generally travel, hunt, and sleep alone, spending much of the year separated from other members of their species.The main exception comes during breeding season, when a male and female meet within their shared territory. Maned wolves are generally monogamous, and the pair may remain together for a period while raising their young before returning to their largely solitary lives.Living alone can make survival more difficult, especially when predators are nearby. Without a pack to provide protection, the maned wolf needs other ways to make itself appear dangerous when threatened.This is where its famous mane comes into play.When a maned wolf senses danger, the dark hair running along its neck and back can stand upright. At the same time, the animal straightens its body and arches its back, making an already tall animal appear even larger and more intimidating.It can also produce a low growl to warn an approaching threat. This is only one part of the maned wolf’s unusual vocal repertoire. The animals are also known for high pitched whines used during greetings, along with distinctive “roar-barks” that can carry over long distances.Even the way maned wolves sleep can be surprisingly complicated.Their activity patterns change depending on where they live and the conditions of their environment. In some parts of Bolivia, for example, maned wolves may be active during the day during the dry season but shift toward nighttime activity during the wet season.In Brazil, populations can show almost the opposite pattern. These changes allow them to adjust their behavior to seasonal conditions, food availability, and other environmental factors.So while the maned wolf may look like something created by combining several different animals, every strange feature serves a purpose. Its long legs help it navigate tall grass, its mane can make it look more threatening, its solitary lifestyle reduces competition, and its powerful scent helps it communicate across its territory.And then there is that unmistakable urine, the strange secret that once had people wondering whether someone had been smoking marijuana inside a zoo.The maned wolf may not actually be a wolf, but it certainly has earned its place among the most unusual creatures in the canine family.
