According to foreign media reports, the World Wildlife Fund researchers photographed carrying a polar bear cub swimming scene. The researchers say this is a new discovery. Because of melting Arctic ice, polar bears need to swim longer distances, cub survival to the test.
According to scientists, because to face the test of long distance swimming, riding a polar bear cub swimming in the mother who helps to survive. This means that the cub's fur to direct contacts with her mother, and part of the body will be in the ice, this would reduce their heat loss. Because the polar bear cub has not yet fully grown fat against the cold, so this new approach is essential for the survival of pups.
According to the World Wildlife Fund plan polar bear tracking data show that the track polar bears in Alaska over the last four years swimming the length of about 350-400 miles.
The female polar bears are being tracked, because the male polar bear's neck than head width, not conducive to the installation of the collar tracker.
According to reports, the polar bear is the world's largest land predator, good swimming, and their reproductive and feeding activity in sea ice above.
World Wildlife Fund scientists said Jeff & # * York, with the melting of Arctic ice, polar bears swimming in the distance will be longer.
He said: "According to a survey of bear tracks in the past four years they swim a distance of approximately 350-400 miles in between, if the pups were forced to swim long distances, this position will help them survive to swim" |
