High Mountain Wolf

The Himalayan or Tibetan wolf appears to be on the verge of being recognised as a distinct species (https://www.theguardian.com/world/2020/feb/21/himalayan-wolf-lopes-recognition-species-oxygen-protection). It may look superficially like a Grey wolf, but these canids show physiological adaptations, enabling them to operate at altitudes where oxygen is in short supply. That could make them sufficiently different to be accorded separate status.
