Wolverines are powerful and smart creatures. They hunt for their survival in cold, northern climates throughout the world. Their habitats include North America, sub-Arctic islands, Eurasia from Scandinavia to Siberia, and Greenland.
A wolverine’s lifespan is about 17 years in captivity and 13 years in the wild. Its mating seasons spans late April to July. This animal typically weighs seven to 34 kilograms and measured 82 to 140 centimeters in length.
Although small, wolverines have unique characteristics that make them creatures one should not threaten. In addition to their strong jaws, massive heads, and sharp teeth, wolverines also have a special defense system: their anal glands can spray a very smelly yellow-green liquid about one-meter in distance to scare off predators.
Also, wolverines’ toes are very similar to a human’s, but instead of nails they have long, sharp claws. A wolverine has a very thick skull and an almost bear-like face. Their broad feet act like snowshoes in the winter. Their coats, made of long, coarse, and dense fur, are unlike most other animals’.
Like wolverines, other members of the weasel family have characteristics that help them hunt: powerful anal glands, slender bodies, and sharp claws. These similar animals include the Gulo gulo gulo—from Europe and Asia—and the G. gulo luscus—from North America.
The wolverine belongs to the weasel family. In contrast to wolverines, weasels and martens have wedge-shaped heads. Another relative of the weasel family is the American badger, which is closely related to martens and the tayra.
Even though it is a small creature, the wolverine is more complex and impressive than it might seem.
