The Arctic fox is a small mammal native to the cold regions of the Arctic. It has a thick, warm coat that changes color with the seasons, turning white in winter to blend in with the snow and brown or gray in summer. This adaptation helps the fox stay hidden from predators and hunt for food, primarily small mammals like lemmings. Arctic foxes are well adapted to their harsh environment. They have small ears and a compact body, which help minimize heat loss. These foxes are also known for their excellent sense of hearing, allowing them to locate prey beneath the snow. They are social animals and often live in family groups.
