The fanged river frog, Limnonectes macrodon, is a large bodied ranid frog now thought limited in distribution to Java and Sumatra.It has long been confused with the similar Limnonectes blythii, which is a species complex ranging widely across the mainland and archipelagos of southeast Asia.A terrestrial species, the fanged river frog lives in lowland forested areas (up to at least 700 m asl) near flowing streams, in which it breeds (Iskandar et al. 2004; Frost 2016).
Limnonectes macrodon is known by multiple common names.Others include Javan Giant Frog, Brown mountain frog, Malaya Wart Frog and Stone Creek Frog.
Although at one time this was a common species, Limnonectes macrodon is now listed by the IUCN as of vulnerable status.It is threatened by habitat loss, degradation of water quality, and over collection as a food source (Iskandar et al. 2004; Warkentin et al. 2009).In addition to being used for local subsistence, it is one of the heavily harvested species supplying frog legs for international export (Defenders of Wildlife 2011).
