The Arctic is home to a variety of animals, including REINDEER, hares, and polar bears. REINDEER, also known as caribou, are large mammals with antlers that live in the northern regions of Europe, Asia, and North America. Hares are small mammals with long ears and hind legs that live in the northern parts of Europe, Asia, and North America. Polar bears are large white bears that live in the Arctic Circle and are the largest land carnivores in the world. All three of these Arctic animals are adapted to living in cold climates and have thick fur coats to keep them warm.
