Polar bears swim 46 miles a day

Based on the electronic device attached to a polar white bear, scientists found that it swam at least 46 miles (74 km) per day, even up to 62.5 miles (100 km). This is the first evidence that bears can swim over such a long distance.

Each year, bears often swim about 625 miles to search for prey like seals and from there bring anecdotes about them, with swimming from island to island, or across the vast bays.

" The new point this time is that we have data showing the time of bears in the country, " said Jon Aars, a researcher in the Norwegian Arctic. "This is the first time such a far-off swim has been recorded by the satellite measurement device on polar bears."

The female bear, equipped with satellite navigation devices, enters the waters on the eastern side of Spitsbergen Island, the Arctic waters of Norway, early on July 20, swims to the northeast and appears on Edgeoya Island one days later. A sensor on the bear's neck will emit different signals when it is in salty sea water, compared to on land or on ice.

Aars said the bear may have swam nearly 62.5 miles because it hardly went straight between these two points 46 miles away. The average speed of the animal is 1.9 - 2.5 miles / hour (3-4 km / hour), equivalent to a pedestrian.
