Lifespan, ageing, and relevant traits

Maximum longevityNot yet established
Observations

Little is known about the longevity of these animals. One wild born specimen was about 9 years old when it died in captivity [0671]. Considering the low reproduction rate of these animals, however, longevity is likely longer, maybe up to 12 years.
