Observations

Little is known about ageing in gorillas. One wild born female was about 53.5 years when she died in captivity [0671]. The record longevity, however, appears to belong to a female called "Jenny" that died at Dallas Zoo from an inoperable stomach tumour at 55.4 years of age. She showed early signs of cataracts.
