Cryptobranchus

The genus Cryptobranchus refers to the hellbender, a type of salamander found in the streams of the eastern and central United States. These large amphibians, growing up to 74 cm (29 inches), have stout bodies, broad tails, and wrinkled skin that aids in respiration. Hellbenders are typically brownish-gray with black spots and are primarily nocturnal, feeding on crayfish, small fish, and worms. They reproduce through external fertilization, with males guarding the eggs until they hatch. The Ozark hellbender is a subspecies with distinct blotchy spots. Cryptobranchus is the type genus for the family Cryptobranchidae, which includes other large salamanders.123
