The Asiatic salamanders (family Hynobiidae) are primitive

Cryptobranchidae), with which they form the suborder Cryptobranchoidea. About half of hynobiids currently described are endemic to Japan.[1]

Hynobiid salamanders practice external fertilization, or

eggs. Parental care is common.[3]

A few species have very reduced lungs, or no lungs at all. Larvae can sometimes have reduced external gills if they live in cold and very oxygen-rich water.[4]

Fossils of hynobiids are known from the Miocene to the present in Asia and Eastern Europe, though fossils of Cryptobranchoids more closely related to hynobiids than to giant salamanders extend back to the Middle Jurassic.[5]
