Guest Videos — Canids of Latin America: Chrysocyon


How charismatic is the next canine listed by our guide?

Enough so to make a BBC film crew sit outdoors next to raw meat on a hot summer night, braving a Brazilian thunderstorm:



These animals also visit during the day, and the monks let visitors watch, if they keep still when the critters come in:



It’s not a fox. It’s not a wolf, either. But it is a member of Family Canidae’s Tribe Canini.

According to Dr. Wikipedia:

The maned wolf’s evolutionary relationship to the other members of the canid family makes it a unique animal.

Electrophoretic studies did not link [maned wolves] with any of the other living canids studied. One conclusion of this study is that the maned wolf is the only species among the large South American canids that survived the late Pleistocene extinction. Fossils of the maned wolf from the Holocene and the late Pleistocene have been excavated from the Brazilian Highlands…

The maned wolf is not closely related to canids found outside South America. It is not a fox, wolf, coyote or jackal, but a distinct canid; though, based only on morphological similarities, it previously had been placed in the Canis and Vulpes genera… Its closest living relative is the bush dog (genus Speothos), and it has a more distant relationship to other South American canines (the short-eared dog, the crab-eating fox, and the zorros or Lycalopex…


This unusual taxonomy and the creature’s red-list status are probably why maned wolves have their own research working group in the Canid Specialist Group.

The convergent evolution of stilt legs in Order Carnivora seems to have happened at around the same time on two different continents: six million years ago in South America for maned wolves and some 5.4 million years ago in Africa for servals. (Thiel)

Now what could have caused both sides of Order Carnivora to evolve features useful for hunting in tall grass at that time?

No one knows for sure. Perhaps it had something to do with climate change and/or the appearance of a new kind of grass?

Whatever the reason, it worked out well for this beautiful but strange-looking doggo!


Some lagniappe:

Family will tell. The dogs bounce around, but cats are stalkers.
