Paedophryne amauensis, also known as the New Guinea Amau frog, is a species of microhylid frog endemic to eastern Papua New Guinea. [2] [4] At 7.7 mm (0.30 in) in snout-to-vent length, it was once considered the world's smallest known vertebrate.
The smallest amphibian (and vertebrate) in the world is a frog from New Guinea (Paedophryne amauensis) with a length of just 7.7 mm (0.30 in). 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 ...

Caecilians have small or absent eyes, with only a single known class of photoreceptors, and their vision is limited to dark-light perception. [17] [18] Unlike other modern amphibians (frogs and salamanders) the skull is compact and solid, with few large openings between plate-like cranial bones. The snout is pointed and bullet-shaped, used to ...
Indonesia is the world's largest exporter of frog meat, exporting more than 5,000 tonnes of frog meat each year, mostly to France, Belgium and Luxembourg.
