The world's 'oldest gorilla' has died in captivity aged 63.
Trudy, believed to be the oldest living Western Lowland gorilla, passed away at the Little Rock Zoo, in Arkansas, US.
She had been at the facility for over 31 years, after being transported from Buffalo Zoo in 1988.
Little Rock Zoo Director Susan Altrui said: “There are so many memories, stories and anecdotes to share about Trudy.
"She is a cherished member of the Little Rock Zoo family.
"To say that she will be missed and that her absence is felt is an understatement. We are glad to know she had a good home with us here."
Trudy was one of the last gorillas captured in the wild and was apparently a 'boss lady', according to former zookeeper Syd Tanner.
She apparently had a 'mind of her own' and stuck to bachelors and all-male groups, which is not normally the case for female gorillas.
Fellow ape expert Catherine Tidwell described Trudy as a 'queen' who 'ruled the roost' and made a humming sound whenever it was time for food or she saw someone she was fond of.
Another elderly gorilla died in January last year, when 60-year-old Vila passed away in San Diego Zoo Safari Park.
The sexagenarian was believed to have been the second-oldest gorilla in captivity in the world.
Vila was a Western Lowland gorilla born in the Congo in 1957, before being hand-reared at San Diego Zoo’s Children’s Zoo.
She gave birth to her first child in 1965, the first gorilla to be born at the zoo.
