Amboli bush frog (Pseudophilautus amboli), a member of the Rhacophoridae, with enlarged vocal sac for mating calls

The Rhacophoridae are a family of frogs that occur in tropical sub-Saharan Africa, South India and Sri Lanka, Japan, northeastern India to eastern China, south through the Philippines and Greater Sundas, and Sulawesi. They are commonly known as shrub frogs, or more ambiguously as "moss frogs" or "bush frogs". Some Rhacophoridae are called "tree frogs". Among the most spectacular members of this family are numerous "flying frogs".

Although a few groups are primarily terrestrial, rhacophorids are predominantly arboreal treefrogs. Mating frogs, while in amplexus, hold on to a branch, and beat their legs to form a foam. The eggs are laid in the foam and covered with seminal fluid before the foam hardens into a protective casing. In some species, this is done in a large group. The foam is laid above a water source so the tadpoles fall into the water once they hatch.[1]

The species within this family vary in size from 1.5 to 12 cm (0.59 to 4.72 in).[1] Like other arboreal frogs, they have toe discs, and those of the genus Chiromantis have two opposable fingers on each hand. This family also contains the Old World flying frogs, including Wallace's flying frog (Rhacophorus nigropalmatus). These frogs have extensive webbing between their fore and hind limbs, allowing them to glide through the air.[2]

Parasites

As many frogs, rhacophorids harbour monogeneans worms in their urinary bladders. The parasite species specialized to this family of frogs belong to the genus Indopolystoma, described in 2019.[4]

Amboli Bush Frog, a rare endemic arboreal tree frog from the Western Ghats of India, displays spectacular mating calls during the heavy monsoon, which can usually exceed 8000-10,000 mm a year. The males are usually smaller than the females and are carried to fertilize the eggs. The species is severely endangered with only small pockets left in the region's evergreen forest. This male was found close to the huts of Kalinga Rainforest Conservation Center in Agumbe, Karnataka, India.
