The wolverine, Gulo gulo, is sometimes compared to a small bear, yet does not belong to the same family. The wolverine is actually related to the otter and the ferret.
Equipped for walking in the snow and braving the toughest winters in its habitat, it travels huge distances in search of food, using its anal glands to leave its scent wherever it goes. Its semi-retractable claws allow it to climb trees and dig under the snow.
A predator and a scavenger, the wolverine is adept at adaptation: when it is hungry, even frozen bones cannot resist its powerful jaws.
