Both males and females grow to an adult length of 24 to 40 cm (9.4 to 15.7 in) from snout to vent, with a total length of 30 to 74 cm (12 to 29 in), making them the fourth-largest aquatic salamander species in the world (after the South China giant salamander, the Chinese giant salamander and the Japanese giant salamander, respectively) and the ...
The Chinese giant salamander eats aquatic insects, fish, frogs, crabs, and shrimp. [10] They hunt mainly at night. As they have poor eyesight, they use sensory nodes on their heads and bodies to detect minute changes in water pressure, enabling them to find their prey.
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 .
Giant salamanders are obligate paedomorphs with partial metamorphosis, [2] but Asiatic salamander goes through a full metamorphosis. The only known exceptions are the Longdong stream salamander , which has been documented as facultatively neotenic, and the Ezo salamander , where a now assumed extinct population from Lake Kuttarush in Hokkaido ...

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]
The giant salamander was identified using DNA by staff at the Zoological Society of London and the Natural History Museum. Newly discovered giant salamander is ‘world’s largest amphibian ...
