Figure 1. A North American giant salamander (Cryptobranchus alleganiensis) shows the characteristic morphology of the cryptobranchids; large robust dorso-ventrally flattened head and body, small eyes, thick legs with stubby digits, lateral folds of skin for respiration, and sensory papillae for detecting water movement and prey (laterally flattened tail not shown).

Figure 2 in The giant salamanders (Cryptobranchidae): Part A. palaeontology, phylogeny, genetics, and morphology

Figure 2. Fossil salamanders strongly support an east Asian (red ellipse) origin for the Cryptobranchoidea. The continents were distributed very differently in the Mid-Jurassic (170 MYA) before continental drift moved them to their present locations. However, Eurasia and North America remained in the Northern Hemisphere. By the Late Pliocene (3 MYA) the continents had moved to their present positions.

Taking tissue samples from tail clips (Image: Amy McMillan) or blood samples (Image: Jeff Briggler) enables conservation geneticists to assess an individual's relationship to other individual cryptobranchids and the relationship of its population to other populations of the same species.
