Observations

These animals show exceptional longevity. One specimen called "Ming" was estimated to live up to 507 years in the wild [1086]. One study found that in animals aged 4-192 years, antioxidant enzymes declined rapidly in the first 25 years, which includes the growth and sexual maturity stages, but afterwards remained stable for over 150 years [0829]. Though more detailed studies are warranted, it appears this species is a case of negligible senescence.
