 Cryptobranchidae (Fitzinger, 1826) Giant Salamanders
The family Cryptobranchidae is comprised of three similar-looking living species, in two genera.
Cryptobranchids are characterized by the absence of lacrimals and septomaxillae, and a curved row of palatal teeth set parallel to the maxillary and premaxillary teeth (Duellmann and Trueb, 1986).
Cryptobranchidae and the Asian family Hynobiidae comprise the suborder Cryptobranchoidea, the ancient or primitive salamanders.

 Cryptobranchidae
The morphological characters given below are the ones standardly used to diagnose the salamander family Cryptobranchidae and to assess its phylogenetic relationships to other salamanders.
Metamorphosis is incomplete in the Cryptobranchidae, leading to a number of paedomorphic characteristics in adults.
Monophyly of the Cryptobranchoidea is supported by molecular evidence (Larson, 1991; Larson and Dimmick, 1993) and by two morphological synapomorphies (fusion of first ceratobranchial and first epibranchial; fusion of the pubotibialis and puboischiotibialis muscles; see Estes, 1981).

, Inner Mongolia, China, and represent basal members of the Cryptobranchidae, a family that includes the endangered Asian giant salamander (Andrias) and the North American hellbender (Cryptobranchus).
These fossils document a Mesozoic record of the Cryptobranchidae, predating the previous record of the group by some 100 million years
This discovery provides evidence to support the hypothesis that the divergence of the Cryptobranchidae from the Hynobiidae had taken place in Asia before the Middle Jurassic period.

Hynobiidae and Cryptobranchidae comprise the primitive or ancient suborder, Cryptobranchoidea.
The smallest groups are the giant salamanders (Cryptobranchidae), and Amphiuma (Amphiumidae), for which there are only three known species in each family.
The families Amphiumidae, Sirenidae, Cryptobranchidae, and Proteidae retain larval characteristics into adulthood, to varying degrees.

In particular, this neoteny can be observed in the families Cryptobranchidae (which looses external gills but retains a respiratory spiracle), Amphiumidae (reduction of limbs, no eyelids, retention of gills), Sirenidae (remains almost totally larval), and Proteidae (retains external gills, loss of eyes).
Among salamanders, fertilization typically involves the deposit of a sperm plug by the male, which is picked up by the cloaca of the female, allowing internal fertilization.
The only salamanders known that practice true external fertilization (male "silts" laid eggs with sperm) are in the families Cryptobranchidae, Sirenidae, and Hynobiidae.

Because the arrangement shown here is the most parsimonious tree resulting from combined analysis of 209 molecular and morphological characters, it is recommended as the best current working hypothesis.
The phylogeny presented here indicates strongly that the salamanders that retain at least some aquatic larval characteristics throughout life (families Amphiumidae, Cryptobranchidae, Proteidae, Sirenidae and parts of the Ambystomatidae and Plethodontidae) do not form a monophyletic group.
Living salamanders are divided taxonomically into ten taxonomic families based upon phylogeny and anatomical features: Ambystomatidae (mole salamanders), Amphiumidae (amphiumas), Cryptobranchidae (hellbenders), Dicamptodontidae (Pacific giant salamanders), Hynobiidae, Plethodontidae (lungless salamanders), Proteidae (mudpuppies), Rhyacotritonidae (torrent salamanders), Salamandridae (true salamanders and newts) and Sirenidae (sirens).

 Great Smoky Mountains National Park - Amphibians (U.S. National Park Service)
In fact, the great majority of vertebrate (backboned) animals, including human visitors, in the park on any given day are salamanders.
Five families of salamanders are represented in the park: Cryptobranchidae, Proteidae, Salamandridae, Ambystomatidae, and Plethodontidae.
The southern Appalachian Mountains, including the Great Smokies, are a major center of evolutionary diversification for the family Plethodontidae, commonly known as the lungless salamanders.
