The family Cryptobranchidae are the largest living salamanders (length may exceed 1.5 meters in Andrias), completely aquatic , and dorsoventrally compressed. The genus Andrias contains the largest living salamanders, and fossil records show species that attained more than 2 meters in length. Metamorphosis is incomplete; external gills are lost in adults but eyelids do not develop and the tail remains compressed laterally.

Generally found under rocks in swift cold water streams and rivers. The genus Andrias occurs in central China and Japan, whereas Cryptobranchus lives in eastern North America. Mating in Cryptobranchus occurs in late summer or early fall. Females lay long, paired strings of several hundred eggs which are fertilized externally by the male in the nest he constructed under a large rock or submerged log.

Asian salamanders of the genus Andrias were literally being eaten out of existence and are now considered highly endangered. There is much work being done on farming them now.

The aquatic nature of these extremely large salamanders pose a challenge in keeping them captively as dose their habita requirements.

The genus Andrias was formerly known as Megalobatrachus, and references to the former name are still common.

Unique in being able to employ asymmetrical suction feeding. They are carnivorous, feeding on fish, other salamanders, worms, insects, crayfish and snails.

Large tanks, and custom enclosure are required for their maintenance in captivity, and the use of chillers is a must.

Filtration is a huge issue as these amphibians require almost perfect water conditions. Simulating the fast unidirectional flow of a river or stream also poses a challenge.

Much more work needs to done with these beautifully ugly giants by both the private and professional sectors.
