See text Megophryidae, commonly known as goose frogs, is a large family of frogs native to the warm southeast of Asia, from the Himalayan foothills eastwards, south to Indonesia and the Greater Sunda Islands in Maritime Southeast Asia, and extending to the Philippines.

The camouflage is accurate to the point of some having skin folds that look like leaf veins, and at least one species, the long-nosed horned frog (Megophrys montana) has sharp projections extending past the eye and nose, which disguise the frog shape.

The following genera are recognised in the family Megophryidae; Amphibian Species of the World and AmphibiaWeb differ on the number of species per genera, leading to the variability in numbers:[4][5] The origin of this group of frogs was largely unknown, due to the lack of members of this family in the fossil record.

Using DNA sequencing, the study indicated the group more likely originated much later during the Cretaceous period, around 77 mya.

[8] While the family is currently restricted to Asia, fossils indicate that it once had a much wider distribution extending to North America.
