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
Newts are also known as "Tritones" (viz., named for the mythological Triton) in historical literature, and "triton" remains in use as common name in some Romance languages, in Greek, in Romanian, Russian, and Bulgarian. The systematic name "Tritones" was introduced alongside Pleurodelinae by Tschudi in 1838, based on the type genus named "Triton" by Laurenti in 1768. Laurenti's "Triton" was renamed to "Triturus" ("Triton-tail") by Rafinesque in 1815. Tschudi's Pleurodelinae is based on the type genus "Pleurodeles" (ribbed newt) named by Michahelles in 1830 (the name meaning "having prominent ribs", formed from πλευρά "ribs" and δῆλος "conspicuous").
