- Observations
Their longevity has been reported to be between 50 and 100 years [0437]. Estimates of longevity in the wild suggest these animals may live over 50 years [0527]. One study found that mortality declines with age in these animals, up to advanced ages, and as such could be a species exhibiting negligible senescence [1150].
