How long do American salamanders stay on land?

Newt is an amphibian with lung cavity and skin breathing. They can move on land, but they need to keep their skin moist to breathe. The skin of salamanders can permeate oxygen through water molecules, but in a dry environment, they can't keep moisture and humidity in their bodies, so it is difficult for them to breathe and metabolize normally. Therefore, American salamander can stay on land for a period of time, but the time will not be long, usually only about 5 hours, which depends on factors such as humidity and temperature in the environment.

American salamander is an aquatic animal, belonging to salamander family. It is native to western North America and lives in freshwater lakes, rivers and streams. In the natural environment, American salamanders often look for food or avoid predators on land instead of living on land.
