Population [top]

Population:This is a common and abundant species. It is found in most rushing forest streams in Peninsular Malaysia, each substantial boulder has one or more A. larutensis on it and one needs to watch carefully to avoid stepping on them accidentally. It appears to have been common historically, and is still considered to be at present (Berry 1975). It is probably the most common frog in forest boulder streams all through the Thai-Malay Peninsula.
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It exclusively occurs on boulders and bedrock in and along fast-flowing, clear-water forest streams, from lowlands to highlands. Tadpoles live in the same streams, attaching themselves to rocky surfaces using their ventral suction area.
Systems:Terrestrial; Freshwater

Use and Trade [top]

Use and Trade: The species is used in medical research but the numbers collected are not at a level to constitute a threat.

Threats [top]

Major Threat(s): The tadpoles are susceptible to water pollution, in particular, sedimentation caused by logging activities. The species is used in medical research but the numbers collected are not at a level to constitute a threat. Future threats could include residential and commercial development, and pollution from domestic and industrial waste water.

Conservation Actions [top]

Conservation Actions: It probably inhabits every significant protected area from Hala Bala to Endau-Rompin. Research is required on the species’ taxonomy, population status, life history and ecology.
