World’s oldest known Gorilla, Colo, passed away in her sleep at the Columbus Zoo and Aquarium. Born in 1956, Colo was the first gorilla to have born in a zoo and she lived a full 20 years more than the average lifespan of gorillas in captivity. Colo was a Western Lowland gorilla. She had developed a malignant tumor under her arm which was removed on December 3 last year. At this moment it is not clear if her death was due to this operation.
Columbus Zoo authorities announced her death via Twitter. Colo will be cremated. The President and CEO of Columbus Zoo Tom Stalf said in a statement, “Colo touched the hearts of generations of people who came to see her and those that cared for her over her long lifetime. She was an ambassador for gorillas and inspired people to learn more about the critically endangered species and motivated them to protect gorillas in their native habitat.”
