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 ...
Eastern newt Amphibians are ectothermic , anamniotic , four-limbed vertebrate animals that constitute the class Amphibia . In its broadest sense, it is a paraphyletic group encompassing all tetrapods excluding the amniotes (tetrapods with an amniotic membrane , such as modern reptiles , birds and mammals ).
The rough-skinned newt (Taricha granulosa) is a newt known for its strong poison. Habitats of rough-skinned newts are found throughout the West Coast of the United States and British Columbia . Their range extends south to Santa Cruz , California and north to Alaska .
Photos of the species show that the newts have black, bumpy skin and orange toes, fingers, and tails. Researchers describe a #newspecies in the Asian newt genus Tylototriton from Hunan Province ...
Amphibians, on the other hand, are numerous in the territory, with eleven distinct species divided into six families.
