The largest carnivorous land mammal is the polar bear (Ursus maritimus). Found primarily in the Arctic region, polar bears are exceptional hunters, primarily preying on seals. They have adapted to extreme cold with thick layers of fat and fur that insulate them against freezing temperatures. Polar bears can weigh up to 1,500 pounds or more, making them formidable in their tundra habitat. Their hunting skills and physical attributes allow them to thrive in the Arctic environment, though they face challenges from climate change and habitat loss.
