The largest land carnivore is the polar bear (Ursus maritimus). Found primarily in the Arctic regions, these powerful animals are well adapted to their cold environment, with thick blubber and fur to insulate against freezing temperatures. Adult male polar bears can weigh between 900 to 1,600 pounds and measure up to 10 feet in length when fully grown. They primarily prey on seals, using sea ice as a platform for hunting. Due to climate change and melting ice, polar bears face significant challenges in their survival, making them an important symbol of the impact of environmental changes on wildlife.
