Many salamanders do not use vocalisations, [70] and in most species the sexes look alike, so they use olfactory and tactile cues to identify potential mates, and sexual selection occurs. Pheromones play an important part in the process and may be produced by the abdominal gland in males and by the cloacal glands and skin in both sexes.
These salamanders do move slowly, which could increase their risk of being caught. [28] Generally, predators of the broad category of toxic Salamandra species can include birds, rats and snakes, as well as other, larger carnivorous mammals like raccoons, minks, wild boars and foxes. [10] One notable predator of S. atra is young snakes. [28]
The South China giant salamander (Andrias sligoi), can reach a length of 1.8 m (5.9 ft). [1] The Japanese giant salamander (Andrias japonicus) reaches up to 1.44 m (4.7 ft) in length, feeds at night on fish and crustaceans, and has been known to live for more than 50 years in captivity. [2]
A 2018 study of mitochondrial DNA revealed that there are five wild clades of the Chinese giant salamander, as well as two only known from captives (their possible wild range was previously unknown). They diverged from each other 4.71–10.25 million years ago and should possibly be recognized as cryptic species .
The Pacific giant salamanders are members of the genus Dicamptodon. They are large salamanders endemic to the Pacific Northwest in North America. [ 1 ] [ 2 ] [ 3 ] They are included in the family Ambystomatidae , [ 1 ] [ 4 ] [ 5 ] or alternatively, in their own monogeneric family Dicamptodontidae.
The South China giant salamander (Andrias sligoi) is a species of very large salamander endemic to southern China, mainly in the Pearl River basin south of the Nanling Mountains. It may be the largest species of salamander and the largest amphibian in the world. It is extremely endangered and nearly extinct in the wild. [3]
As larvae the western grotto salamander lives in springs and streams near cave entrances. [1] As adults, They migrate deep into the caves themselves and live out their lives underground. [1] They prefer waters between 5.5 and 16.5 °C, and feed on small, cave-dwelling invertebrates such as Gammarus, though they are also known to eat guano as well.

It is the largest salamander in North America. A member of the family Cryptobranchidae, the hellbender is the only extant member of the genus Cryptobranchus.
