Have you always wondered how animals can live and even thrive in the extreme climates of the Arctic? If they freeze and feel miserable during winter, or if they actually feel as comfortable as we do in our own living-room? In this educational tool-kit, you will learn about the amazing and sometimes odd ways animals have adapted to living in the extreme environments of the Arctic, and how the scientists believe these animals will cope with a changing climate. This is part 1 of 3 in a series of tool-kits on animal adaptations. It introduces the topic, and covers mainly animals living in water. Part 2 and 3 go more in-depth and focus on deer and birds.
