MALI: A hungry polar bear has been witnessed diving and swimming underwater for more than three minutes without coming up for air, smashing a previous record of 72 seconds.
The feat, described in the journal Polar Biology, may illustrate the desperate measures polar bears must take to survive as climate change melts away their traditional hunting grounds on the sea ice of the Arctic Ocean, says one of the authors of the study.
The new record was witnessed by veteran Arctic guide Rinie van Meurs last August. He had been taking a family out by boat to see polar bears near the Svalbard archipelago in northern Norway, when they spotted a “very, very skinny” adult male polar bear, he recalled in an interview with CBC’s As It Happens.
Polar bears rely on sea ice as a habitat for hunting seals, but as the Arctic gets warmer as a result of climate change, there is less and less sea ice, especially in the summer.
