Lifespan, ageing, and relevant traits

Maximum longevityNot yet established
Observations

While females may reproduce much sooner, males generally do not mate in their first year of life. It has been estimated that these animals live up to 4 years in the wild [0542]. Record longevity in captivity, however, is only 3.1 years [0671]. Further studies are necessary.
