The largest living amphibian is the 1.8 m (5 ft 11 in) South China giant salamander ( Andrias sligoi ), but this is dwarfed by prehistoric temnospondyls such as Mastodonsaurus which could reach up to 6 m ...
The marsupial frogs are a disputed family (Amphignathodontidae) in the order Anura. [1] When treated as a separate family, it consists of two genera, Gastrotheca and Flectonotus.
