The Arctic fox is indeed a tough animal; it can survive the harsh and frigid Arctic temperatures. It has short rounded ears, a short muzzle, and fur-covered soles. This is an adaptation to the freezing cold climate of the Arctic region.
The behaviour of the Arctic fox depends on climate. It lives in burrows. During a blizzard, it tunnels into the snow to create shelter. During summers, it preys on rodents like lemmings. It occasionally feeds on birds as well. During the winters, the Arctic fox also preys on reindeer in addition to rodents and birds. Lemmings however, are their most common prey; a family of foxes can eat dozens of lemmings each day.
Often, it scavenges on carcasses left by larger predators such as wolves and polar bears. It also eats the eggs of many birds. When food is abundant, the Arctic fox buries the surplus as a reserve. This animal is hunted for its fur and this practice has led to a decline in its numbers.
