Snowstalker

The snowstalker (Gulo fatalis) is a large, solitary, saber-toothed, white-colored musteline mustelid from the North European Ice of 5 million AD. It has evolved from the wolverine (Gulo gulo), and is the chief enemy of shagrats.

One big difference that the snowstalker has from most other mustelids is its method of killing prey. Its canine teeth have developed into 6-inch (15-centimeter) slashing weapons, designed for inflicting deep wounds on large prey bigger than themselves (a case of convergent evolution with saber-toothed felids). It is territorial, but as the tundra on which it lives supports very few large plant-eaters, there is little in the way of regular prey here. The territory of a single snowstalker covers several square miles.
