The polar bear is a bear native largely within the Arctic Circle encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. It is the world's largest land carnivore and also the largest bear, together with the omnivorous Kodiak bear, which is approximately the same size. A boar (adult male) weighs around 350–700 kg ( ), while a sow (adult female) is about half that size.
