Polar bear's super swimming ability

Polar bears can swim continuously for more than 675km during 10 days in search of un melted ice sheets, according to research by American scientists.

Scientists from the US Geological Survey (USGS) have attached GPS tracking devices to the necks of more than 500 female polar bears in the Beaufort Sea, Alaska. After 5 years of follow-up, the team found that in the summer months when the Arctic ice is at its lowest, polar bears have to swim further and for longer to find new ice that has not yet melted.

Polar bears have the ability to swim farther to enjoy recording with global warming

Specifically, one-third of the 52 polar bears observed can swim continuously for more than 48km. A bear can swim 354km continuously without a break, while another polar bear set a record when swimming continuously for 675km during 10 consecutive days.

The results of the USGS survey are evidence that polar bears are fond of recording very rapidly with changes in the Arctic environment. However, some scientists worry that having to swim continuously for a long time will make polar bears become weaker and reduce fertility. Currently, Arctic dandruff has been classified as a serious endangered animal by the US government.

'Polar bears can swim continuously for a long time, meaning they have more chances to survive. However, having to swim a long distance requires a lot of energy. Thus, a polar bear lost an average of 20% of its body weight after a month of swimming on the sea , 'USGS said on the Daily Mail.

Scientists also reported that the average time of polar bears was 2.3 times more underwater than on ice sheets. This proves that the amount of ice in the Arctic summer is much lower than in the past.

Polar bears often have to swim the most during the period from July to October every year. They cannot exist without the ice they use to hunt seals - their main food source.
