Not all aquatic salamanders are considered newts, however. More than 100 known species of newts are found in North America, Europe, North Africa and Asia. Newts metamorphose through three distinct developmental life stages: aquatic larva, terrestrial juvenile (eft), and adult.
Salamandridae is a family of salamanders consisting of true salamanders and newts. Salamandrids are distinguished from other salamanders by the lack of rib or costal grooves along the sides of their bodies and by their rough skin. Their skin is very granular because of the number of poison glands. They also lack nasolabial grooves.
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.

It is endemic to the southern Zagros Mountains in Iran where it is known from just four streams.
Salamander diversity is highest in eastern North America, especially in the Appalachian Mountains; most species are found in the Holarctic realm, with some species present in the Neotropical realm. Salamanders never have more than four toes on their front legs and five on their rear legs, [ 3 ] but some species have fewer digits and others lack ...
The California newt or orange-bellied newt (Taricha torosa), is a species of newt endemic to California, in the Western United States. Its adult length can range from 5 to 8 in (13 to 20 cm). [ 2 ] Its skin produces the potent toxin tetrodotoxin .
Hundreds of wart-covered creatures were seen “slowly moving along the muddy bottom” of a lake in India, researchers said.
This newt can reach a length of 20 cm (7.9 in). The tongue is small and is free on the sides and only slightly towards its base. The teeth on the palate are in two oblique rows that meet at the front of the mouth. The skull has a thick, bony fronto-squamosal arch, a feature of all salamanders. [2]
