Megophryidae are a large family of frogs native to the warm southeast of Asia, from the Himalaya foothills eastwards, south to Indonesia and the Greater Sunda Islands in the Malay Archipelago, and extending to the Philippines. As of mid-2008 it encompasses approximately 70-100 species of frog divided between 12 genera. For lack of a vernacular name, they are commonly called megophryids.
The megophryids are notable for their camouflage, especially those who live in forests often looking like dead leaves. The camouflage is accurate to the point of some having skin folds which 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.
Megophryids range in size from 2 to 12.5 centimetres in length. The adults' tongue is noticeably paddle-shaped. Their tadpole can be found in a variety of waters – ponds and streams especially. Their tadpoles are extremely diverse because of the variety of habitats they inhabit.
