Arctic fox
This fox can live in the cold north even when it is -30F. Their thick fur keeps them warm. The fur of the Arctic fox provides the best insulation of any mammal. Its broad, fluffy paws let it walk on ice and snow to look for food. The Arctic fox has very good ears so that it can hear small animals under the snow. When it hears an animal under the snow, it jumps and punches through the snow to catch its victim. Arctic foxes are omnivores. They feed on lemmings, arctic hares, fish, birds, eggs, fruit, insects, small seals, and carrion.
