Subgroups

The Cryptobranchoidea are a suborder of salamanders found in the eastern United States, China, Taiwan, and Japan. They are known as primitive salamanders, in contrast to Salamandroidea, or advanced salamanders.[2]

Some species of the fully aquatic Cryptobranchidae family are known as giant salamanders due to their large size.

Description[edit]

This suborder contains only two families at present. Other families became extinct in the past and are only known as fossils.
