Observations

These animals do not commonly live more than 10 years in the wild with the oldest animal ever found being 18 years old [0434]. One wild born animal was still living in captivity at 25.8 years of age [0671]. Given the lack of detailed studies, however, their maximum longevity is classified as unknown.
