The Rotung Oriental Frog (Ingerana borealis) is a rare species found in lowlands of Northeastern India, Myanmar, Bangladesh, Bhutan and China, usually below 400 meters above sea level, but sighted up to 1000 meters asl (Sailo et al. 2009).It inhabits slow and fast moving streams in and near tropical forests.Sailo et al. (2009) moved the species from genus Micrixalus to Ingerana, based on study of morphology and behavior.Within the genus, I. borealis is taxonomically grouped along with species I. charlesdarwini and I. borealis, which have smooth skin, narrow toe tips with less than half of the toe length webbed (Iskandar et al. 2011). Ingerana borealis has a small and fragmented distribution, and is threatened by habitat loss and degradation due to water pollution.It is protected in India (Lau 2004).
