How Do Arctic Foxes Change Color With the Seasons? #Video

Every winter, the Arctic tundra becomes a world of endless white. Yet somehow, one small predator blends into the snow almost perfectly. The Arctic fox is famous for changing its coat with the seasons—appearing bright white during winter and turning brown or gray when summer arrives. But how exactly does that transformation happen?

In this episode of History of Simple Things, we explore the fascinating biology behind how Arctic foxes change color with the seasons. From the role of daylight and hormones to the molting process and pigment changes inside their fur, this remarkable adaptation helps the fox survive in one of the harshest environments on Earth.
