The vargen, or wolf, is a wild carnivorous mammal belonging to the family Canidae. Known for their social behavior, wolves typically live in packs, which are family groups that work together to hunt and raise their young. They are found in various habitats, including forests, tundras, and grasslands, across North America, Europe, and Asia. Wolves are characterized by their keen senses, particularly their sense of smell, which is about 100 times more sensitive than that of humans. They play a crucial role in maintaining the balance of ecosystems by controlling prey populations, which helps to promote biodiversity in their habitats.
