Clawed salamander

The genus Onychodactylus, commonly known as clawed salamanders, is a genus of salamanders endemic to eastern Asia. Prior to 2012, it was thought to contain only two species: O. fischeri in the Korean peninsula & Russian Far East, and O. japonicus in Japan, on the islands of Shikoku and Honshū. Later taxonomic revisions have led to many new, microendemic species to be described in the genus.^[1] All species are lungless with moderately developed parotoid glands. They inhabit moist, forested mountains near small rivers, streams, and lakes. Adults of each species can reach a length of 19 cm.
