Polar bears are the largest land carnivores and among the largest mammals on the planet. As a matter of fact, the only other carnivores who come close to their impressive size are Kodiak brown bears who just like polar bears, sit comfortably atop the food chain. This being said, polar bears are mostly marine mammals, as they spend most of their lives walking the cold Arctic sea ice.
As we are about to find out, they have evolved a series of unique characteristics to facilitate their survival in such a harsh environment, characteristics that not many other creatures possess. Here are, then, ten very interesting facts about polar bears.
9They can swim for over one week non-stop
Polar bears have huge, webbed paws that help them to cut through the water at speeds of 6mph or more. At the same time, polar bears can swim nonstop for 62 miles when necessary. When in dire circumstances, they can swim for extremely long distances without taking a break. In fact, the longest distance ever recorded was in 2011 when a mother bear swam 426 miles over the course of 9 days. She lost 22% of her body weight by the time she reached land and her cub unfortunately died.
