This is Jenny. Jenny is recognized as the world's oldest gorilla in captivity
Gorillas in the wild normally would live to age 30 or 35, but health care and protection from predators has extended their lifespan in zoos. Of the roughly 360 gorillas in North American zoos, only four are over the age of 50. All of them are female. Jenny is the oldest of them all at 55.
Caretakers at the Dallas Zoo, where Jenny lives, celebrated her birthday with a four-layer frozen fruit cake and banana leaf wrapped treats.
