Fisherman Discovers 200-Year-Old Chinese Giant Salamander
A fisherman in southwest China stumbled upon a 200-year-old Chinese giant salamander weighing over 100 pounds. The four-and-a-half foot long specimen greatly surpasses the average lifespan of the critically endangered species. Giant salamanders are thought to live 80 years in the wild. The salamander found in China has been transferred to a research facility for study.

Species of the giant salamander are found in both China (Andrias davidianus) and Japan (Andrias japonicas). Oddly enough, the closest relative to these living fossils is the Hellbender (Cryptobranchus alleganiensis) found in eastern North America. The hellbender, on average, grows to half the size of the giant species. KU Herpetology Collections Manager Luke Welton says giant salamanders diverged from the hellbender 65 million years ago.
Despite the distance between their homes, all three species have similar habitats and lifestyles. Welton says the three species spend little time on land due to poorly developed lungs, and instead absorb most of their oxygen through folds of skin on their sides. As a result of this preference, all three prefer cold, fast-running streams and lakes. Salamanders often seek refuge beneath large submerged rocks and boulders.
Several specimens of the hellbender and both species of giant salamander are part of the KU Biodiversity Institute Herpetology Collections.
