Lungless salamanders
Plethodontidae
There are over 250 species of lungless salamanders. They can be found in North America, southern Europe and tropical America. Their front legs have four toes. They really do lack lungs, and must keep their skin wet in order to effectively breathe through it. Some lungless salamanders are entirely aquatic. Others live mainly on land but stay wet by hiding in damp, shady places.
