Adult lungless salamanders have four limbs, with four toes on the fore limbs, and usually with five on the hind limbs. Within many species, mating and reproduction occur solely on land. Accordingly, many species also lack an aquatic larval stage, a phenomenon known as direct development in which the offspring hatch as fully-formed, miniature ...

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 ...

Batrachoseps is a genus of lungless salamanders (plethodontids) often called slender salamanders. They can be distinguished from other lungless salamanders by the four toes they have on each foot. They can be distinguished from other lungless salamanders by the four toes they have on each foot.
Desmognathus fuscus is a species of amphibian in the family Plethodontidae (lungless salamanders). [2] [3] The species is commonly called the dusky salamander or northern dusky salamander to distinguish it from populations in the southern United States which form several distinct species, the southern dusky salamanders (D. auriculatus, D. valentinei).
