Assessment Information [back to top]
Category Data Deficient (DD)
Criteria Data Deficient (DD) ver 3.1

Listed as Data Deficient, because only two individuals werefound in a single location in Roangchari, Bandarban, for only once (Khan, 2012). Although the known AOO is very small andcontinuing decline of the quality of habitat is evident, the species is look-alike of a few other species found in the area.

Date Assessed 25/06/2014

It has not yet been evaluated(IUCN-Bangladesh 2000).

Geographic Range [back to top]
Global Range

This species is found in Bangladesh, India, Thailand, Malaysia, Indonesia, Brunei Darussalam and The Philippines (Diesmoset al. 2009).


Only two individuals of Hylarana nicobariensis were found in a small ditch at the top of a bushy and cultivated hill in Roangchari, Bandarban, in November, 2010, during a night search (Khan 2012, Hasan et al. 2014). It is likely to occur in other similar habitats of the Chittagong Hill Tracts.

Habitat and Ecology [back to top]

This species is presumably nocturnal and crepuscular. Calls during the dusk and at night. Feeds on small aquatic organisms. Not much is known about its breeding. Males call from ditches, flooded fields, and ponds. The species breeds in rainwater ponds, flooded fields, lowland swamps, tree holes, and roadside ditches (Chanda 2002).


This frog occurs in a variety of habitats like bushy and grassy vegetation in and around freshwater swamps, low-hill forests, swamp forests, secondary growths and human-dominated areas with sufficient vegetation and water. In Bangladesh, it was reported only from a small wetland situated in a hilltop.

Not known.

Home Range

Not known.

Active Period

This frog is active at night.

Host Plant


Threats [back to top]

Loss of natural vegetation due to expansion of agriculture, particularly burning of natural vegetation for shifting cultivation, together with excessive use of water, are responsible for the loss of natural habitats.


No report.


Tribal people in the Chittagong Hill Tracts deliberately hunt the frogs for meat, including this species.



Conservation Information [back to top]
Wildlife Legislation

Not included.


Not listed.



Recommendation Research [back to top]

Status and distribution should be determined by thorough survey in the southeast and northeast of Bangladesh.


The known AOO should be protected by involving the local Khumi tribal people, because the spot is just beside a Khumi village who are dependent on the land and water of this frog's habitat.

Captive Stock

There exists no captive stock in Bangladesh.
