# West Virginia spring salamander

The West Virginia spring salamander (Gyrinophilus subterraneus) is a species of troglobitic salamander in the family Plethodontidae. It is endemic to West Virginia, the United States.

The salamander is only found in the General Davis Cave in Greenbrier County and lives in cave stream passages with large amounts of decaying organic matter. It is considered endangered and is under review for listing under the Endangered Species Act of 1973.

General Davis Cave forms the downstream end of the 3.5-square-mile (9.1 $km^2)$ Davis Hollow drainage basin. This cave has been purchased by The Nature Conservancy and is closed to the public in order to protect this salamander and a small bat colony.

Like the western grotto salamander (Eurycea spelaea), the West Virginia spring salamander can undergo complete metamorphosis, which is very rare among cave salamanders. It is not known how often metamorphosis occurs, but when it does, it happens after the larvae have reached a very large size.
