The Chalazodes Bubble-nest Frog, Raorchestes chalazodes, is listed as ‘Critically Endangered’ on the IUCN Red List of Threatened SpeciesTM. The Chalazodes Bubble-nest Frog was first found in 1874 in ‘Travancore’, Kerala, India. Then, this species was not recorded for over 125 years until it was rediscovered in July 2000 on the south-western slopes of the Cardamom Hills, Kerala, India. The species is now known to be a nocturnal and arboreal frog that lives in the understory of moist tropical evergreen forest. It can also be found in disturbed secondary habitat. Cardamom Hill remains the only known site where the Chalazodes Bubble-nest Frog is known to occur, however this species is difficult to distinguish from other similar species. This species is believed to breed by direct development.
Chalazodes Bubble-nest Frog is listed as Critically Endangered because it has a highly restricted range of less than 10 km2 and its habitat is severely fragmented. Its population continues to decline. This species is threatened by the conversion of natural forest to intensively cultivated areas and plantation. An improved protection of habitat within the range of this species is recommended.
There are no known conservation efforts underway for this species and it is not found in any protected areas. However, there are currently field studies being conducted to better understand this species.
