Arctic fox

The Arctic fox has learned to adapt to the far north and the cold that is found in these regions. No other mammal has such insulating fur, and if a snowstorm comes, they simply roll up into a small ball – then their thick and bushy tail can keep them warm. It only needs to increase its metabolism to keep warm at -40 degrees Celsius. In the red fox, this limit is -10 degrees Celsius. At the same time, the Arctic fox is able to store fat that partly acts as an insulator and partly as a kind of reserve. This means that the Arctic fox can go without food for several weeks. The Arctic fox changes its fur between summer and winter. The Arctic fox comes in 2 color varieties. The common white Arctic fox and the more grayish blue fox. Both color varieties have in common that they change to a brown fur in the summer. When they live on the tundra, they will live on snow and ice in the winter, and on brown grassland in the summer. So for the sake of camouflage, it’s smart to change color.
