What are polar bears' predators?

Polar bear predators include humans and other polar bears. Polar bear cubs are also prey to wolves. While polar bears are not prey to walruses, the animals do pose a threat to the bears as rivals on the food chain, particularly when the animals hunt in water.

Although Inuit people consume polar bear meat and use bear fur, the greatest threat humans pose to polar bears comes from habitat destruction. Male polar bears sometimes eat baby polar bears for unknown reasons to scientists. Only 42 percent of polar bear cubs that live in Alaska reach a year of age, as of 2006.
