Lifespan, ageing, and relevant traits

Maximum longevity
Not yet established

In the wild, these animals do not generally live more than 3 years and most die within their first year of life. Potential longevity has been estimated at 5 years [0434]. One wild born specimen was about 5.4 years of age when it died in captivity [0671]. Anecdotal reports of animals living up to 8 years have not been confirmed. Further studies are necessary to better estimate the maximum longevity of this species.
