The polar bear is a predator animal adapted to life in the harsh tundra habitats. As the world's largest land carnivore, it has a thick layer of body fat and a water-repellent coat that allows it to survive in cold temperatures. Polar bears primarily feed on seals, which they hunt both on land and in the sea. They have large, paddle-like feet and strong limbs that enable them to swim long distances with ease. Their keen sense of smell helps them detect prey from far distances. Despite being well adapted to their environment, polar bears face numerous threats due to climate change, pollution, and human activities. As a result, they are considered a vulnerable species by the International Union for Conservation of Nature (IUCN).
