The green salamander (Aneides aeneus) is a mid-sized salamander, measuring 3 ¼-5 inches (8.3-12.5 cm), with a flattened, elongated body, flattened head, and square toes. Its coloration resembles green lichen-like markings on a dark background, with a ventral region that is generally lighter than the dorsal patterned side. Green salamanders live predominantly in wet, damp crevices and are the only salamander of the genus Aneides found in the eastern United States. Historically, their range extended from Nickajack Cave, Tennessee, north to Baileysville, West Virginia, and through the Cumberland and Kanawha sections of the Allegheny Plateau.
