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.^[1]

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