Observations

The development of these animals depends highly on the ambient temperature. Sexual maturity, for instance, takes an extra 14 years to occur at temperatures of 10 degrees C [0749]. Based on mortality patterns, these animals have been estimated to live over 102 years in the wild; signs of ageing have not been detected [0934]. In captivity, record longevity is 58 years [0485]. As such, this species appears to be a case of negligible senescence.
