Observations

Maximum longevity has been estimated to be around 60 years, which is plausible. Males appear to be longer-lived than females and attain sexual maturity at later ages [0434]. Pregnant females have been reported up to 55 years of age. The MRDT was calculated to be about 10 and the IMR 0.015 for females [0784]. One wild born specimen was still alive in captivity at 37.8 years of age [0671].
