The mossy frog is a species of frog in the family 'Rhacophoridae'. It is found in northern Vietnam and China. The common name "mossy frog" arises from the fact that its skin is a mottled green and brown that resembles moss growing on rock, and forms an effective form of camouflage.

They have large sticky pads on their toes and a soft underbelly. They measure about 61 mm (2.4 in). This species will curl into a ball when frightened, and play dead.

Its natural habitats are primarily evergreen rainforests and subtropical forest where they have been found inside pools in hollowed logs, placed by the local villagers. It is a semi-aquatic animal that is found in caves and steep rocky cliffs. Breeding takes place in rock cavities or tree holes. It is insectivorous.
