Why does the Arctic fox turn white in winter?

Arctic foxes do not turn white in the winter. They are born white and stay that way all year round. This is an adaptation strategy to help them blend into their snowy environment and avoid predators. Arctic foxes have a thick coat of fur that helps to keep them warm in the harsh Arctic climate. Their white fur makes it difficult for predators to see them against the snow. This adaptation has helped the Arctic fox to survive and thrive in its extreme environment.
