Sri Lanka rock frog
Nannophrys ceylonensis
Nannophrys ceylonensis, commonly known as the Sri Lanka rock frog or the Ceylon streamlined frog, is a species of frog. It used to be placed in the large frog family Ranidae but a phylogenetic study was undertaken using DNA sequences and it is now included in the family Dicroglossidae. It is endemic to Sri Lanka where its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, rivers and streams.

Description
Female Sri Lanka rock frogs grow to a length of about 5 centimetres (2.0 in) while males grow to 4 centimetres (1.6 in). The colour is olive green or yellowish-brown, mottled with brown patches. The legs have transverse bars of brown. When sitting on alga covered rocks it is well camouflaged.
Range & habitat
The Sri Lanka rock frog is endemic to south, central and western Sri Lanka where it is found in wet tropical forests at altitudes of up to 1,200 metres (3,900 ft) above sea level. It is a largely aquatic species and occurs in fast flowing mountain streams, under boulders and on wet rocks beside waterfalls. It is also found on land in disturbed areas where there are suitable breeding locations such as wet seeps. The tadpoles are semi-terrestrial and are sometimes found on wet rocks beside torrents.
