Lifespan, ageing, and relevant traits

Maximum longevityNot yet established
Observations

Little is known about the longevity of these animals. It has been reported that they can live for 12 years [0467], which is possible but has not been confirmed. One animal was still alive after 8.2 years in captivity [0671]. Further studies are necessary to better estimate the maximum longevity of this species.
