[1] The Tennessee cave salamander inhabits the southern Cumberland Plateau in the Appalachian Mountains in the United States.

[1] The salamander's diet consists of amphipods and other small aquatic invertebrates that live in caves.

[4] G. palleucus lives in caves and is dependent on the quality of the water in the streams that flow through them.

Threats it faces include pollution, siltation, flooding, increased water flow and the filling of sinkholes and dumping of trash.

Its total area of occupancy is less than 2,000 km2 (800 sq mi) and its population in Custard Hollow Cave in Tennessee seems to be decreasing.
