Pełniejszy materiał źródłowy / excerpt

The hellbender (Cryptobranchus alleganiensis), also known as the hellbender salamander, is a species of aquatic giant salamander endemic to the eastern and central United States. It is the largest salamander in North America. A member of the family Cryptobranchidae, the hellbender is the only extant member of the genus Cryptobranchus. Other closely related salamanders in the same family are in the genus Andrias, which contains the Japanese and Chinese giant salamanders. The hellbender is much larger than any other salamander in its geographic range, and employs an unusual adaption for respiration through cutaneous gas exchange via capillaries found in its lateral skin folds. It fills a particular niche—both as a predator and prey—in its ecosystem, which either it or its ancestors have occupied for around 65 million years. The species is listed as Vulnerable on the IUCN Red List of Threatened Species due to the impacts of disease and widespread habitat loss and degradation throughout much of its range. Eastern hellbender populations are dropping quickly across most of their range, nearly 80% are declining or disappearing altogether. A reason for this is the loss of forest along streams, which they rely on to keep their habitats stable and clean. In many places, the populations are mostly older individuals, with few young hellbenders showing up to replace them.

The Cryptobranchidae (commonly known as giant salamanders) are a family of large salamanders that are fully aquatic. The family includes some of the largest living amphibians. They are native to China, Japan, and the eastern United States. Giant salamanders constitute one of two living families—the other being the Asiatic salamanders belonging to the family Hynobiidae—within the Cryptobranchoidea, one of two main divisions of living salamanders. The largest species are in the genus Andrias, native to east Asia. The South China giant salamander (Andrias sligoi) can reach a length of 1.8 m (5.9 ft). The Japanese giant salamander (Andrias japonicus) reaches up to 1.44 m (4.7 ft) in length, fee…
