Family Cryptobranchidae is a group of salamanders that includes two living species: the giant salamander from Asia and the hellbender from North America. However, there are several other words that can be used as synonyms for this family. These include "crypto-branch," "cryptobranch," and "giant salamander family." All of these terms are used interchangeably to refer to this group of aquatic salamanders that are known for their large size and flattened, paddle-like feet. While they may not be as well-known as other species of salamanders, the Family Cryptobranchidae includes some of the most unique and fascinating amphibians in the world.
