The Odaigahara salamander is a small amphibian from the cryptobranchid family. It lives only in the mountain forests of central Japan and leads a hidden lifestyle in moist places.
The Odaigahara salamander differs from other cryptobranchids in its unique pattern and adaptation to cold mountain forests. It is important for nature as a predator of small animals and an indicator of water body purity.
Immature form that undergoes metamorphosis before adulthood.
