What is a genus of a toad?

A newt is an amphibian of the Salamandridae family, although not all aquatic salamanders are considered newts.

About two thirds of all species of the family Salamandridae are commonly called "newts", compromising the following genera:

• Calotriton, Spanish brook newts
• Cynops, firebelly newts
• Echinotriton, crocodile newts
• Lissotriton, small bodied newts
• Mesotriton, Alpine newts
• Neurergus, spotted newts
• Notophthalmus, Eastern newts
• Ommatotriton, banded newts
• Pachytriton, paddle-tail newts
• Paramesotriton, warty newts
• Pleurodeles, ribbed newts
• Taricha, Pacific newts
• Triturus, crested newts
• Tylototriton, crocodile newts

The term "newt" has traditionally been seen as an exclusively functional term for salamanders living in water, and not a systematic unit.
