- a surviving species from the Pleistocene Extinction (Video)
The Maned wolf is a very fascinating animal. Despite its name, the maned wolf is not a wolf at all, or a fox, coyote, or dog. It is the only member of the Chrysocyon genus, making it a truly unique animal, not closely related to any other living canid. It is believed that the maned wolf is the last surviving species of the Pleistocene Extinction, which wiped out all other large canids from the continent.
The maned wolf is native to South America, but is mainly found in Argentina, Paraguay, Bolivia and Peru. The ancestors of the maned wolf are thought to have spread from North to South America about two million years ago. Broken away from other wolf species in North America, the maned wolf evolved into the unique animal that it is today.
It is known as the "stilt-legged fox" because that is what it mostly resembles. It is around 3 feet high, and weighs around 50 pounds, with most of that height coming from the legs. It is also a beautiful red color, with black and white highlights, much like the red fox.

Near the dawn of time, the story goes, Coyote saved the creatures of Earth. According to the mythology of Idaho's Nez Perce people, the monster Kamiah had stalked into the region and was gobbling up the animals one by one. The crafty Coyote evaded Kamiah but didn't want to lose his friends, so he let himself be swallowed. From inside the beast, Coyote severed Kamiah's heart and freed his fellow animals. Then he chopped up Kamiah and threw the pieces to the winds, where they gave birth to the peoples of the planet.
European colonists took a very different view of the coyote (Canis latrans) and other predators native to North America. The settlers hunted wolves to extinction across most of the southerly 48 states. They devastated cougar and bobcat populations and attacked coyotes. But unlike the other predators, coyotes have thrived in the past 150 years. Once restricted to the western plains, they now occupy most of the continent and have invaded farms and cities, where they have expanded their diet to include squirrels, household pets and discarded fast food.
Researchers have long known the coyote as a master of adaptation, but studies over the past few years are now revealing how these unimposing relatives of wolves and dogs have managed to succeed where many other creatures have suffered. Coyotes have flourished in part by exploiting the changes that people have made to the environment, and their opportunism goes back thousands of years. In the past two centuries, coyotes have taken over part of the wolf's former ecological niche by preying on deer and even on an endangered group of caribou. Genetic studies reveal that the coyotes of northeastern America — which are bigger than their cousins elsewhere — carry wolf genes that their ancestors picked up through interbreeding. This lupine inheritance has given northeastern coyotes the ability to bring down adult deer — a feat seldom attempted by the smaller coyotes of the west.
