As this genus was found to contain several distinct evolutionary lineages, the alpine newt was split off as genus Mesotriton in 2004. [7] However, the name Ichthyosaura was published earlier and is now accepted as the valid genus name for the alpine newt, while Mesotriton is a junior synonym .

Also, rough-skinned newts' upper teeth form a V shape, while those of the California newt form a Y shape, but this is difficult to ascertain on a living specimen. [ 4 ] 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).
To escape predators, newt larvae have been found to shift their microhabitat to a temperature range that exists outside the predator's preferred temperature range. [33] Larvae that are in the metamorphosizing stage tend to prefer warmer temperatures than those in the stage following metamorphosis. [33]
The SHH gene is a member of the hedgehog gene family with five variations of DNA sequence alterations or splice variants. [37] SHH is located on chromosome seven and initiates the production of Sonic Hedgehog protein. [37] This protein sends short- and long-range signals to embryonic tissues to regulate development. [38]
Paramesotriton labiatus is a species of newt in the family Salamandridae. [2] [3] It is endemic to Guangxi, China.In literature prior to 2011, this species may have been confused with Paramesotriton chinensis, Pachytriton granulosus, or Paramesotriton ermizhaoi (the last now in synonymy). [2]
Female mate choice is an important concept in evolutionary biology because it bears on female and male reproductive success. Experiments were carried out with Lissotriton vulgaris in which female newts were paired sequentially with two males having different degrees of genetic relatedness to the female.
Schmidtler's smooth newt (Lissotriton schmidtleri) is a newt species found from northwestern Greece and southeast Bulgaria over East Thrace across the Bosphorus to northwest Anatolia. [ 1 ] [ 5 ] [ 6 ] : 234 Its range borders that of the smooth newt ( L. vulgaris ), the Greek smooth newt ( L. graecus ) and Kosswig's smooth newt ( L. kosswigi ...
