- Observations
As in other similar species, these newts feature extensive regeneration capabilities [0483]. They can live up to 15 years in the wild [0749]. One specimen kept as a pet was still alive when over 25 years of age (website feedback), which is a plausible anecdote. A female reportedly lived for 15 years in captivity [0528]. In some populations, sexual maturity can be reached in 1 year, but it usually takes at least 3 years. Some data suggests males may reach sexual maturity slightly sooner than females [0749].
