Spotted paddle-tail newt
"Pachytriton" species are stout-bodied, smooth-skinned aquatic newts. Their heads are large and flattened, and they have conspicuous labial folds and short, stubby legs and toes. They breathe through both lungs and skin. 
"P. brevipes" ranges from 5.5 to 7.5 in as an adult. It has prominent labial folds, long digits, and smooth skin, which differs from the tuberculate skin typical of newts.
Newt
Although some species, such as the rough-skinned newt ("Taricha granulosa") in North America or the smooth newt ("Lissotriton vulgaris") in Europe, are still relatively common, populations of newts throughout their distribution range suffer from habitat loss, fragmentation, and pollution. This affects especially the aquatic breeding sites they depend on, but also their land habitats. Several species, such as the Edough ribbed newt ("Pleurodeles poireti"), Kaiser's spotted newt ("Neurergus kaiseri"), or the Montseny brook newt ("Calotriton arnoldi") are considerered threatened by the IUCN, and the Yunnan lake newt is a tragic example of a newt species that has gone extinct recently.
