The population of amphibians of Madagascar is made up exclusively of frogs.
There are 311 named species of frogs on Madagascar,[1] but several hundred have been identified using DNA barcoding and remain to be formally described.
Two further species are introduced: the ranid frog Hoplobatrachus tigrinus and the toad Duttaphrynus melanostictus.
85 species are threatened with extinction, nine of which are considered by the IUCN as critically endangered.
Their numbers are largely affected by major alterations of habitat due to deforestation and the expansion of paddy fields and villages, and to a lesser extent, by illegal international trade.
