Eastern newts have a lifespan of about 8–10 years in the wild, but some individuals have been known to live up to 15 years. [6] Eastern newts have three stages of life: (1) the aquatic larva or tadpole, (2) the red eft or terrestrial juvenile stage, and (3) the aquatic adult.
Notophthalmus species are East American newts similar in shape to the European newts (cf. Triturus). As a distinct characteristic of their own, both sexes have three to four large pores that lie in a row on the temple. The skin is smooth and soft in the water form and the tail is strongly flattened laterally.
Newts metamorphose through three distinct developmental life stages: aquatic larva, terrestrial juvenile (eft), and adult. Adult newts have lizard-like bodies and return to the water every year to breed, otherwise living in humid, cover-rich land habitats. Newts are threatened by habitat loss, fragmentation and pollution.
