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 ...
The spotted paddle-tail newt (Pachytriton brevipes) is an amphibian native to southeastern China; it was named in 1876. [2] A member of the family Salamandridae , it is closely related to the spotless paddle-tail newt ( Pachytriton labiatus ).

The crayfish will also disrupt ...
