Rhyacotriton

Rhyacotriton are a genus of small salamanders who depend on headwater streams and seeps in the Pacific Northwest. For full species accounts, professional photos, etc., please see the links below.

I am interested in this species because they are indicators of cold, clear, highly oxygenated water. They are also an ancient clade closely related the Plethodontids, with complex genetic relationships and behavior.
