P. yonahlossee is a large Southern Appalachian woodland salamander typically differentiated by its large size and its distinctive rust-colored dorsum.As with all other members of the genus, Plethodon yonahlossee is lungless and a direct developer, meaning no larval stage is seen; instead, the young hatch into miniature adults, and fully metamorphosed adult individuals are characterized by a ...
Plethodon is part of the family Plethodontidae (lungless salamanders) and the subfamily Plethodontinae.The genus Plethodon can be divided into two subgenera: the nominal subgenus Plethodon, which includes up to 49 eastern species (the bulk of diversity in the genus), and the subgenus Hightonia, [5] which includes 9 species native to the western part of North America.
The cave salamander is a relatively large lungless salamander, ranging in total length from 10 to 20 cm (4 to 8 in). The tail makes up a significant proportion of the total length, up to 60–65%. [4] Post-metamorphic individuals have orange to reddish orange backs and a pale, unmarked ventral surface.
