Wolverine
Top 9 in Top 10 World's Most Solitary Animals
Wolverines resemble a hybrid between a dog and a bear, but they are actually mustelids, a species of weasel. They actively chastise any creature that approaches them and do not merely wish to dwell alone. One of the most hostile creatures in the world, wolverines are known to occupy enormous territory and fiercely defend them.
These hardy creatures live alone and require a lot of space to wander. In quest of food, individual wolverines can cover up to 15 miles each day. Wolverines frequent the isolated boreal woods, taiga, and tundra in the northern latitudes of Europe, Asia, and North America due to these ecological needs.
