New footage from a polar bear body Cam River exhibit how these ursine inhabitant of the Arctic gaming , swimming and hunt .
Just free by the U.S. Geographic Survey , the footage is from a period - of - view tv camera around the neck opening of a distaff polar bear from the southern Beaufort Sea , just north of Alaska . harmonize to the USGS , scientist fitted the female person with the photographic camera to dog her daily natural process , conduct and feeding rate .
A female polar bear wearing a body cam play fights with another polar bear in the southern Beaufort Sea.
The footage captures a bear’s - eye - view of the world as the distaff plods across the ice , chows down on a seal , has a play fight with another polar bear and drown in the ocean . The end of the project , according to the USGS , is to better understand howpolar bearsare respond to declines in sea ice in the Arctic .
gelid bears ( Ursus maritimus ) were listed as jeopardize under the Endangered Species Act in 2008 . The master reason for the listing , harmonise to the U.S. Fish & Wildlife Service , was the continuing loss of sea ice , whichthreatens the bears ' power to huntfor Navy SEAL during the wintertime . A 2015 study in the daybook Ecological Applications launch that polar bear populations in the southern Beaufort Seadeclined between 25 percent and 50 percentfrom 2001 to 2010 .
The International Union for Conservation of Nature ( IUCN ) approximate that there are about 26,000 polar bears split into 19 unlike populations across the Arctic . The bears feed mostly on ring seals and bearded seals , according to conservation organization Polar Bears International , which is what makes them so vulnerable to Arctic melt . As the fall freezing total later in the Arctic and the spring melt starts preferably , bear are adhere on substantial ground , unable to hunt seal , accord to a 2013 review clause in the journal Topics in Companion Animal Medicine .
" Polar bears have few alternatives if their home ground ( the ocean Methedrine ) and their access to their ringed seal quarry rapidly disappear,“the author wrote .
And sea ice is rapidly disappearing . Scientists have been observingrecord lows in ice extent for yearsand now portend that the Arctic may be entirely ice - free in the summerby the heart of the century . This year , sea ice in the Arcticactually retreated briefly in November , an result scientists say was virtually unprecedented . Winter sea ice has been attend to retreat only once before , in November 2013 , but that drop was 5,400 square miles ( 13,986 square kilometer ) compared to 2016 ’s 19,300 satisfying miles ( 49,987 sq klick ) .
