AnAge entry for Notophthalmus viridescens

Classification (HAGRID: 00169)

Taxonomy: Kingdom: Animalia
    Phylum: Chordata
        Class: Amphibia (Taxon entry)
            Order: Caudata
                Family: Salamandridae
                    Genus: Notophthalmus
Species: Notophthalmus viridescens
Common name: Eastern newt
Synonyms: Triturus viridescens, Diemictylus viridescens

Maximum longevity: 25 years (captivity)
Source: website feedback
Sample size: Medium
Data quality: Acceptable
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].
