Abstract

Anjudiva archipelago in the Arabian Sea is close to the mainland on the west coast of India. It constitutes eight small island patches seen parallel and close to the central Western Ghats. Islands have rocky, laterite, open grasslands and forests. As there are no previous studies on the faunal diversities of these islands, the present study is undertaken to record amphibian species availability within the islands. The present study records two species of dicroglossid frogs through primary surveys and questionnaire methods. Since saltwater is considered a barrier for amphibian dispersal, we hypothesize that these species might have lived in these islands for a long period when all of the islands were connected to the mainland historically, as the wild flora species display a similar pattern to Western Ghats diversity. On the other end, introductions of these two species of frogs could be human-mediated in the process of getting fresh water to the islands.
