Kingdom Phylum Class Order Family

Scientific Name: Megophrys nasuta
Species Authority: (Schlegel, 1858)
Common Name(s):
English Borneon Horned Frog, Horned Toad, Large Horned Frog, Malayan Horned Frog
Taxonomic Notes: This species is generally recognized as being distinct from Megophrys montana (e.g., Taylor 1962; Inger and Stuebing 1997; Manthey and Grossmann 1997), although other authors have treated it as a subspecies of M. montana (e.g., Grandison 1972; Dring 1979).

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor(s): Peter Paul van Dijk, Djoko Iskandar, Robert Inger
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)
Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Geographic Range [top]

Range Description: This species is known from Yala, southern Thailand (Taylor, 1962), throughout Peninsular Malaysia (Berry, 1975; Dring, 1979), Tioman Island, Singapore (Lim and Lim, 1992; Leong, 2000), Sumatra, Bintan, all parts of Borneo and the Natuna Islands. It occurs up to 1,000m asl.

Population [top]

Population: It is regularly encountered, and its characteristic call is frequently heard in suitable habitat. It is uncommon in Singapore (Lim and Lim, 1992).
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: It inhabits intact lowland and submontane rainforest, generally in the vicinity of forest streams. Adults are terrestrial in habits, but tadpoles live in clear forest streams (Dring, 1979).
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): Loss and fragmentation of the species' habitat are the major threats. Local populations might become exposed to the hazards of stochastic events. The species is harvested for the national and international pet trade, which might affect local populations.

Conservation Actions [top]

Conservation Actions: This species occurs in most protected areas of Peninsular Malaysia (Kiew, 1987) and Singapore (Lim and Lim, 1992). In Borneo and Sumatra the expansion of effective preservation of lowland forests linked by forested corridors is essential. It has been bred in captivity occasionally by zoos (Frankfurt/Main, Germany) and private hobbyists (Schmidt, 1976; Pfeuffer, 1989).
