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 it survive in harsh climates and evade predators. Arctic foxes are well adapted to their environment, with a compact body and short ears to minimize heat loss. They primarily feed on small animals like lemmings and birds, but they are also known to scavenge on polar bear leftovers. Their keen sense of hearing helps them locate prey beneath the snow.
