Northern pygmy salamander Northern pygmy salamander The northern pygmy salamander (or northern pigmy (sic), "Desmognathus organi") is a terrestrial species of salamander in the family Plethodontidae and genus "Desmognathus". Along with the southern pygmy ("D. wrighti") and the seepage salamander ("D. aeneus"), these are some of the smallest salamander species in North America and can be found in higher elevations in the southern Appalachians.

Dorsal coloration can
