Onychodactylus fuscus

Onychodactylus fuscus, the Tadami clawed salamander, is a species of clawed salamander from Japan.^[1] It is known to occur in four different localities in the Fukushima and Niigata Prefectures,^[2] including Tadami and Sanjō.^[3] The species grows 14 centimetres (5.5 in) to 16 centimetres (6.3 in) long,^[3] and differs from the Japanese clawed salamander (O. japonicus) by having a long tail and wide head, as well as lacking a dorsal stripe.^[2] O. fuscus lives in streams^[3] and breeds during the winter.^[2] The species is closely related to Onychodactylus intermedius. It shares much of its habitat with O. japonicus, but the two species are reproductively isolated.^[2]
