Abyssinian Wolf - Canis simensis
Despite appearing more coyote or fox-like in appearance, and previously being thought to be anything from jackal to domestic dog mutation, molecular genetics now place the “Abyssinian wolf” (now commonly known as the Ethiopian Wolf) much closer to grey wolves than any other canid. They are the most critically endangered canine species that is still extant in the wild.
In addition to being incredibly rare, Abyssinian wolves have a fairly distinct lineage from the grey wolves, and are highly specialized for their niche in the Ethiopian ecosystem. Their teeth are spaced significantly farther apart than other canids, to more effectively catch and eat small-to-medium-sized rodents. Each individual hunts by itself during the day, but they still retain the pack dynamic that many other carnivores have, at least while resting.
Interestingly, though once widespread, no known tribes use the Abyssinian wolf within their folklore, though Ethiopia now views the species as a national pride. This is in sharp contrast to the grey wolf, which is widely used in Native American and First Nations folklore, and many other canid species.
