Wolverine (Gulo gulo)

The Wolverines are the largest land dwelling member of the weasel family. They almost look like small bears with brown hair and yellowish stripes on their sides. They are found in arctic and alpine regions of the north including Canada, Siberia, Alaska, and Russia. These areas are extremely cold in the winter and there is only a short period of warm summer every year. 

Wolverine has many special adaptations that allow it to survive in its northern climate.
It has long fur that is resistant to freezing and does not retain water, so that they can keep warm in its cold environment. Moreover, it's legs are so strong with relatively large feet in comparison to its body allowing it to walk on top of the snow. Its semi retractable claws enable them to hunt, as well as digging and climbing. The Wolverine can also give off an unpleasant odor when danger is detected. It also has special teeth, which is rotated 90 degrees and perfect for ripping meat off of a carcass that has been frozen solid and crushing bones to get at the marrow. It gives the Wolverine an advantage as other predators may not be able to eat such a carcass.

Wolverines
are omnivores, they usually prey small animals such as rabbits and rodents, but they do eat a bit of vegetarian fare. Sometimes, they would even bring down animal that is five times its size. During winter, they would dig into burrows and eat hibernating mammals, or look for  frozen carcasses.
