Everyone knows that polar bears are good swimmers, but the amazing journey of this bear beats all. In an incredible feat of strength and endurance, one female polar bear swam through the icy waters north of Alaska nonstop for almost 10 days, covering 420 miles as she searched for drift-ice hunting grounds.
Researchers say it's the longest swim by a polar bear ever recorded. Scientists in the arctic were able to track the epic swim through the Beaufort Sea because the female was wearing a GPS radio collar.
"We are in awe that an animal that spends most of its time on the surface of sea ice could swim constantly for so long in water so cold," the leader researcher told the BBC. "It is truly an amazing feat."
The researchers had been tracking the bear for two months as she looked for food for herself and a cub. During that time, the bear lost more than one-fifth of her body fat. Long swims such as this may become more common for polar bears as increased sea ice melts push the bears to swim farther in search of sustenance, caution researchers.
We are inspired by this polar bear's power and perseverance. To help protect polar bears and their natural habitats, check out the programs of the World Wildlife Fund.
