A polar bear swam continuously for over nine days, covering 687km (426 miles), a new study has revealed. Scientists studying bears around the Beaufort sea, north of Alaska, claim this endurance feat could be a result of climate change. Polar bears are known to swim between land and sea ice floes to hunt seals. But the researchers say that increased sea ice melts push polar bears to swim greater distances, risking their own health and future generations. 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. George M. Durner In their findings, published in Polar Biology, researchers from the US Geological Survey...
