The only polar bear ever born in the tropics has died in Singapore of age-related ailments.
"We have jointly made the difficult but necessary decision to not revive Inuka from anaesthesia on humane grounds," the Singapore Zoo said in a statement.
The bear was born at the zoo and at 27, had outlived his counterparts in the wild by more than a decade.
But his presence has been a subject of controversy among conservationists and animal rights activists.
Recent physical examinations on Inuka revealed that he had been suffering from arthritis, dental issues and ear infections. Weakening limbs also hindered the aging bear's ability to walk.
"As much as we would like to keep Inuka with us for as long as possible, our ultimate responsibility is his welfare," said Cheng Wen-haur, Wildlife Reserves Singapore's deputy chief executive officer and chief life sciences officer.
"Our decision to let Inuka go was made with the knowledge that his health issues have seriously impacted his welfare. Beyond the point where we can ensure a good quality of life for Inuka, the greater kindness would be to relieve him from prolonged suffering."
Singapore, which sits one degree above the equator, seems like the last place for a furry, arctic-native species to be found.
But Inuka, born on 26 December 1990, was Singapore Zoo's fourth polar bear. He lived in a climate-controlled Frozen Tundra enclosure, reports BBC.
Conservationists and animal rights activists campaigned against the presence of polar bears in Singapore's world-class zoo in 1978.
Following animal welfare discussions, the zoo announced in 2006 that it would not bring in any more polar bears after Inuka.
His death has been emotional for many animal lovers in Singapore, who have been expressing their grief on social media and sharing memories of their last polar bear.
