The Berry Cave salamander (''Gyrinophilus gulolineatus'') is a species of salamander in the family Plethodontidae, endemic to the Ridge-and-Valley Appalachians of eastern Tennessee in the United States. Its natural habitat is inland karsts where it lives underground. It is threatened by habitat loss. ==Description== This salamander resembles the Tennessee cave salamander (''Gyrinophilus palleucus'') but grows to a larger size, has a more spatulate snout, a broader head and more pigmentation. The premaxilla bones at the tip of the snout are completely divided in adults of this species while they are not in the Tennessee cave salamander. The larvae have small, functional eyes and they can detect vibrations in the water with the help of mechanoreceptors which are located on the head and sides. If they proceed to the full adult state, their eyes become functionless.〔
