World s oldest Sumatran orangutan dead
Puan described as the "grand old lady" of Perth Zoo was euthanised on Monday due to age-related complications the BBC reported.
She had been at the zoo since 1968 and was officially recognised by Guinness World Records as the oldest of her species in 2016.
A critically endangered species Sumatran orangutans rarely reach age 50 in the wild the zoo said.
Believed to have been born in a jungle in Sumatra Indonesia in 1956 Puan left an "incredible legacy" of 11 children and a total of 54 descendants across the US Europe and elsewhere the zoo said.
Some of Puan s descendants have been released back into the wild in Sumatra.
According to the World Wildlife Fund there are only about 14 600 Sumatran orangutans.
