It is easier to resist the harsh conditions of the Arctic winter as you move, but when you stay still for a while, the frost begins to penetrate clothing and eventually forces you to get up again and warm up by walking. Then you will understand how resilient the animals that spend days and nights in these conditions are, and you will begin to notice the strategies they use. The foxes curl into a ball and blanket the sensitive snout covered with shorter fur with its tail. This way, they can rest right on the snow even in heavy frosts — like a fox in this photo, which briefly raised her head only to check whether I am worth its attention. After a moment, it decided I am not, hid its face again, and continued to rest.
