Liaoning clawed salamander is endemic to China. It is found in densely vegetated mountainous areas at an altitude of about 600m. It often lives near the source of streams or springs with cool water and many stones. It comes out of hibernation in early April and lives on land, but not far from the water. It hides in humid environments during the day; it is active at dusk or after rain, and preys on shrimps, earthworms, millipedes, tadpoles, adult insects and their larvae.

The breeding season is from early May to early June, and eggs are mostly laid at night. The female salamander lays a pair of spindle-shaped egg bags, one end of which is interconnected to form a "handle" and adhered to the stone (usually not on branches); the egg bag is 21-28mm long and 6-10mm in diameter, with a total of 12-17 eggs (Li Jianli, 2004); the female salamander carries 3-24 eggs (18.8, n=6, Poyarkovetal., 2012). It takes 2 years for the larvae to complete metamorphosis.

Currently, only one distribution point of this salamander has been found in China. Due to deforestation and pesticide application, the ecological environment quality of its habitat has declined and the population is very small. Threatened level: Poyarkovetal. (2012) recommended that it be listed as Vulnerable.

Listed in the first level of the "List of National Key Protected Wildlife in China".
