[Still Waters]

The world's oldest known Sumatran orangutan has died in an Australian zoo aged 62, leaving behind 54 descendants.

Puan, described as the "grand old lady" of Perth Zoo, was euthanised on Monday due to age-related complications.

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.
