One of the most diverse mammals in the Arctic tundra is the Arctic fox (Vulpes lagopus). However, it can withstand cold to an extent of -50°F with its dense, seasonal fur, small body, and bushy tail. It is a scavenger and opportunistic predator that preys on lemmings, birds, fish, and carrion.
The winter coat, which changes to pure white, melts into snow. When in summertime, the fur turns to brown or gray, and this is used to blend in with the rocks and the tundra plants. Arctic foxes are known to live in dens to keep off predators and extreme weather conditions.
These are circumpolar foxes that are distributed throughout Alaska, Greenland, Canada, and Siberia. Although they are not faced with the threat at the moment, climate change and disturbing habitats jeopardize their food supply. The family and students studying wildlife have the opportunity to see the seasonal behavior pattern, diet strategy, and social interactions.
