Distribution and Habitat

Country distribution from AmphibiaWeb's database: Sri Lanka


View distribution map in BerkeleyMapper.
Terra Typica: "Ceylon" . It is distributed in the hills of southern, western and central Sri Lanka from 60 to 1070 m asl. It can be found on rocks in cascades and in wet boulders in lowland and submontane forests. It can be difficult to spot as its coloration blends in on rocks with algae.

Life History, Abundance, Activity, and Special Behaviors
While adults are found on rocks in cascades, its tadpoles are semi-terrestrial and occur in shallow sheets of water in seeps. They are well-adapted to rapid flowing creeks.

Possible reasons for amphibian decline
