The name of the largest land carnivore is the polar bear (Ursus maritimus). Adult male polar bears can weigh between 900 to 1,600 pounds and can reach lengths of up to 10 feet, making them the largest terrestrial carnivores. They are primarily found in the Arctic regions and are highly adapted to cold environments, with their thick fur and layer of blubber providing insulation against icy temperatures. Polar bears mainly feed on seals, which they hunt by waiting near breathing holes in the ice. As climate change continues to impact their habitat, polar bears are facing significant challenges to their survival.
