Maximum longevity: 25 years (captivity)
Observations: As in other similar species, these newts feature extensive regeneration capabilities (McGann et al. 2001). They can live up to 15 years in the wild (http://amphibiaweb.org/). 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 (http://www.pwrc.usgs.gov/neparc/). 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 (http://amphibiaweb.org/).
