Polar bears are love to be excellent swimmers , but newfangled research suggests that they are also superb divers .
This thin polar bear recently impressed researchers with his excellent diving skills.
scientist latterly observed a gelid bear dive that lasted 3 minutes , 10 second , shatter the late known criminal record by about 2 moment . The researchers — Ian Stirling from the University of Alberta in Canada , and Rinie van Meurs , a naturalist and polar expedition leader from the Netherlands — werestudying diametric bearsin the Norwegian archipelago of Svalbard ( located between continental Norway and the North Pole , Orient of Greenland ) , when they witnessed this epic underwater swimming . The researchers discover the nose dive in the August edition of thejournal Polar Biology .
Polar bearsare known to dive for food , say Stirling and van Meurs , who note in their news report that these animals typically stay drown for anywhere between 3 and 30 seconds when diving . Sometimes , they ’ll stay submerged longer to appear for kelp , but the prospicient recorded kelp nosedive last only about 1 min , 12 seconds , they said .

This record - breaking honkytonk was also for solid food , but this bear had bigger prey in nous . The bony diametrical bear , which the researcher keep from the deck of a ship , was hunting a group of three whiskered seals that were lollygag about on a shroud of float ice , visit an meth floe . The bear slipped into the water and started swimming toward the seal before diving below the Earth’s surface to continue what the researchers called his " aquatic stalk . "
After spend more than 3 second underwater , the polar bear " exploded " out of the H2O and propelled itself midway onto the shabu ice floe , right in front of where one of thesealswas resting . alas for the hungry bear , the seal got away , the investigator enjoin . But the entire hunt was recorded on video and on film , leave the researchers to affirm that the icy bear had not come up up for air before hurl onto the water ice .
To put the bear ’s dive into perspective , the medium human being can hold his or her breath for about 2 minute underwater , though even that is a stint for some tribe . And some citizenry can check themselves to control their hint for much longer than that . ( There are various techniques for increasing the clip between breaths . )
The polar bear ’s ability to hold its breath for so long is interesting to the researchers because it could be a sign that these beast are develop to survive in ahabitat that is rapidly changing . Global warming is leading to a famine of ocean frosting , the researchers said , signify diametrical bears have less ice on which to hound . As such , the animals must expend more time in the water than they did antecedently when hunt down for seals and other terrestrial prey .
" It is potential that the ability to hold its breathing spell for so long may indicate the initial growing of a meaning adaption for living and hunting in its marine surroundings , " the researchers publish in the bailiwick .
Polar bear depart from their ancestors , dark-brown bears ( Ursus arctos ) , between 400,000 and 500,000 year ago , which is quite late in evolutionary terms . The polar bear ’s proclivity for underwater breath hold up may be a trait that still has n’t fully evolved , but it ’s unlikely that the animal can evolve fast enough to adapt to life at the chop-chop shrinking icy shabu caps , Stirling and van Meurs said .
