The world's oldest Sumatran Orangutan has been euthanised at a Perth Zoo, leaving behind a legacy of 54 descendants.
Sumatran orangutans, found in the northern parts of the Indonesian island of Sumatra, do not usually live beyond 50 in the wild. It was also known that some of her relatives were released into Sumatra. "She is survived by 11 children and a total of 54 descendants across the US, Europe and elsewhere".
According to Ms. Thompson, she had an independent personality and a distant attitude.
Puan's genetics were responsible for just under 10 per cent of the global zoological population of the species, Thompson said.
Born in 1956, she was noted by the Guinness Book of Records as being the oldest verified Sumatran orangutan in the world.
"Puan demanded and deserved respect, and she certainly had it from all her keepers over the years".
Hart paid a moving tribute to Puan, who she described as a "quiet, dignified lady" who would "tap her foot to make you hurry along" if a zookeeper was late with dinner.
Martina Hart, Puan's chief zookeeper wrote an obituary for the ape in The West Australian newspaper today.
She leaves two daughters at the zoo, along with four grandchildren and a great grandson.
Behind the collapse in primate numbers is an increase in industrial agriculture.
Nearly all (94 per cent and 97 per cent) of the primate populations in these countries are in decline.
