The Asiatic salamanders (family Hynobiidae) are primitive found all over Asia, and in European Russia. They are closely related to the (family Cryptobranchidae), with which they form the suborder Cryptobranchoidea. About half of hynobiids currently described are endemic to Japan, but their range also covers parts of China, Russia, Afghanistan and Iran.[(Hasumi 2002).]
Hynobiid salamanders practice external fertilization, or spawning. And, unlike other salamander families which reproduce internally, male hynobiids focus on egg sacs rather than females during breeding.[(Hasumi, 2002).] The female lays two egg sacs at a time, each containing up to 70 eggs. Parental care is common.
A few species have very reduced lungs, or no lungs at all. Larvae can sometimes have reduced external if they live in cold and very oxygen-rich water.[Hasumi, M. (2002). About hynobiids. Retrieved May 8, 2005 from [1].]
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.
