How do lungless salamanders breathe?
The red salamander (Pseudotriton ruber) is found through much of the eastern United States. It belongs to a family of lungless salamanders (Plethodontidae) that breathe only through their moist skin. Although this may seem to be a handicap to their survival, there are more species in this family than in any other family of salamander.

Although they look like lizards, salamanders, like frogs, are amphibians.
Like frogs, salamanders have four legs and moist skin and live in wet environments.
But unlike frogs, salamanders have long, flat tails, which help them swim.
Aquatic salamanders are usually found in freshwater environments, such as ponds and streams. Land-dwelling salamanders inhabit damp forests and can be found crawling on moss-covered rocks and fallen logs.
One of the largest groups of salamanders are the red salamanders. These animals are found primarily in Appalachian wetlands in the southeastern United States. Some live in mountain streams as high as 1500 meters.
Red salamanders belong to a family of lungless salamanders, the Plethodontidae. These salamanders breathe by taking in oxygen through their moist skin. If their skin became dry, they would not be able to breathe.
Young red salamanders are called larvae and have gills. Red salamanders mature more quickly in warmer climates. They reach maturity after 1-1/2 to 3 years.
They may breed all year except in the coldest months. They lay their eggs late each year, usually in fall.
