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. [8] 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.
The red-bellied newt is brown on the upper body with a red underbelly, has grainy skin, and grows to between 5.5 and 7.5 in (14 and 19 cm). It can be distinguished from other coastal newts, not only by its red belly, but also by the lack of yellow in its eyes. Breeding males develop smooth skin and a flattened tail. [4]
The Pacific newts (Taricha) and the Eastern newts (Notophthalmus) with together seven species are the only representatives in North America, while most diversity is found in the Old World: In Europe and the Middle East, the group's likely origin, eight genera with roughly 30 species are found, with the ribbed newts (Pleurodeles) extending to ...

Paddle-tail newt longevity in the wild is currently unknown, but in captivity it usually ranges from 10 to 20 years. Paddle-tail newts, uniquely, are known for their communication. They fan their tails when they are trying to attract the attention of another newt, when they are startled or frightened, or when approached by a conspecific.
The male red-bellied newt often has a dark, broad coloring across the vent, while females do not. [3] Breeding males develop smooth skin and a flattened tail. The red-bellied newt can be distinguished from other coastal newts by its red belly and a lack of yellow in its eyes.
Common over most of its range, the palmate newt is found in a variety of habitats, including forest, marshes and pasture. [11] [4]: 224–225 It is less abundant in cultivated areas, but can adapt to gardens. [1] [10] For reproduction, the newts accept different types of stagnant water bodies, preferably fish-free; acidic ponds are well tolerated.
