Colo — a Western lowland gorilla born in 1956 — was reportedly the first gorilla ever born in a zoo and lived more than 20 years longer than the average captive gorilla. Her death comes shortly after she had a malignant tumor removed from under her arm Dec. 3. However, it is currently unknown if the cancer is ultimately what caused her death. She will be cremated and her ashes will be buried at an undisclosed on-site location, according to a statement from the zoo.
“Colo touched the hearts of generations of people who came to see her and those that cared for her over her long lifetime,” said Tom Stalf, the zoo’s president and CEO. “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.”
