Polar Bear Swam Non-Stop Nine Days to Reach Safety
Researchers at the US Geological Survey in Alaska tracked a female polar bear as it swam nine days to cross 685 kilometres of open Bering Sea before finally reaching the safety of an ice floe. En route the mother lost her cub. When she finally clambered out onto the ice she had lost 22% of her body weight.
