The Siskiyou Mountains salamander (Plethodon stormi ), also called the Siskiyou Mountain salamander, exists only in isolated locations along the Klamath River in northern California and southern Oregon. It is a close relative of the Del Norte salamander, and some herpetologists believe it may be a subspecies of that animal.
The Siskiyou Mountains salamander is rich brown in color with white speckles. It is about 9 cm (4 in) long, not counting the tail, which is variable in length. Like all of the plethodontids, it lacks lungs and respires through its moist skin. It is nocturnal, prefers cool, moist environments, and is most active during rainfall or high humidity. It stays underground during hot periods and freezes.
Plethodon stormi is an IUCN Red List endangered species in California. Logging and damming have reduced its habitat.
