Observations

Although ageing has not been studied in detail, these animals appear to be short-lived. Record longevity in captivity is 5.4 years [0671]. Considering their size, a longer lifespan could be expected. It is possible that their maximum longevity is slightly understimated, but there is no data to suggest a much longer longevity.
