Observations

It has been reported that these animals have bred at 15 years of age and some have lived for more than 20 years in captivity [0434], which is possible but unconfirmed. One male specimen was kept as a pet for 18 years and acquired when about 4 years of age, making it 22 years-old, which is a plausible anecdote (website feedback). Record longevity in captivity is 17.2 years [0671].
