Clawed salamander

The genus Onychodactylus, commonly known as clawed salamanders, is composed of three species, all endemic to eastern Asia. O. koreanus is found on the Korean peninsula, while O. fischeri is found in the Russian Far East and O. japonicus is found in Japan, on the islands of Shikoku and Honshū.^[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.
