The oldest living gorilla in captivity has died at her home in the Dallas Zoo.
Zoo spokesman Sean Greene said Friday that Jenny was euthanized at age 55 because of an inoperable tumor in her stomach.
Jenny basically had stopped eating and drinking recently, and zoo officials decided to euthanize her Thursday night after test results showed she was unlikely to recover.
She was 1 of 5 gorillas at the Dallas zoo.
In May, the zoo held a big birthday bash to celebrate Jenny's longevity. Gorillas in the wild normally would live to age 30 or 35, experts say. Of the roughly 360 gorillas in North American zoos, only four are over 50.
