How do Penguins, sled dogs, and otters live in some of the coldest areas on Earth?
People normally think of Penguins as cold weather animals; and they are. Some may live in warmer climates, but in general the Penguin lives in some of the coldest regions of the Earth. The question for today is, how do penguins and other animals not only survive, but thrive, in such frigid conditions. The average temperature in the Antarctic is a very chilly -58 degrees Fahrenheit. Therefore, Penguins never can forget to wear their cold weather gear. The penguin has a layer of blubber just below the skin that insulates its body. They then have a layer of downy feathers under an upper layer of feathers which overlaps and adds another layer of protection. When the birds go swimming or there is wet precipitation they have glands under their wings that contain oil which gives them a water tight seal. Try to imagine trying to endure that type of cold. Even with the protection of a house it would be difficult to stay warm. Scientists who study the region have to wear layers of clothing even
