Meet The Beautiful Arctic Fox – The Hardiest Of All Arctic Animals

If a fox can't find food, or if the weather gets really bad, it can dig a snow den and hunker down for up to two weeks. As long as a fox is warm, it can slow down its heart rate and metabolism, which helps the animal save energy so it doesn't have to eat as much. It's sort of like how bears hibernate, but for a shorter period of time. Once the animal emerges from its den, it'll try to hunt again. With food in its belly, the arctic fox has a better chance of making it through another long, dark winter.
