Lifespan, ageing, and relevant traits

Maximum longevity
Not yet established
Observations

At high altitudes these animals may be semelparous, meaning they reproduce only once in their lifetime [0469]. It has been estimated that these animals live up to 1.3 years in the wild [0542], or maybe up to 1.5 years [0610]. Due to a lack of detailed studies, maximum longevity could be underestimated and is considered unknown.
