It was a rare sighting of Polar Wolves (Arctic Wolves).
They’re extremely hard to research because they spend the entirety of their lives in the most northern parts of the Queen Elizabeth Islands in Canada on Ellesmere Island & some in Northwestern Greenland. They only migrate during the winter months of December- Jan/Feb when temperatures drop to nearly -51°C (-60) below. They live in extremely cold conditions & are mostly obscure from interacting, unless they’re filmed while hunting.
