PORTLAND — Oregon Zoo officials say Coco the chimpanzee has been euthanized. She was believed to be about 60 years old.
The zoo’s Hova Najarian said Friday that Coco was the oldest animal at the Portland facility.
Primate curator Jennifer Davis told KGW-TV that the chimp had suffered a debilitating medical issue earlier in the week and the most humane option was to euthanize her.
Coco’s actual birth date was not known. She was donated to the zoo in 1961. She is survived at the zoo by two of her daughters.
Najarian says the median life expectancy for chimpanzees is about 32 years for males and about 39 years for females.
