The world’s first gorilla born in a zoo, a female named Colo who became the oldest known living gorilla in the US, has died in sleep less than a month after celebrating her historic 60th birthday.
At 60, Colo was the oldest zoo gorilla on record and exceeded her normal life expectancy by more than two decades, the Columbus Zoo and Aquarium said.
On December 22, Colo celebrated her 60th birthday surrounded by thousands of fans and with birthday wishes coming from around the world.
