The polar bear, also known as the white bear, northern bear, or sea bear, is a large bear native to the Arctic. It is one of the two largest land carnivore species and the top predator within its area.

While their numbers thin north, there is evidence of polar bears all the way across the Arctic. Population estimates are generally
