Amolops larutensis
Amolops larutensis, also known as the Larut sucker frog, is a species of frog native to the Malay Peninsula, found from southernmost Thailand to Malaysia. It is distinctive for its large adhesive discs on its fingertips and smaller ones on its toe tips, which aid in clinging to rocky surfaces in its fast-flowing stream habitat.

About Amolops larutensis
Amolops larutensis, commonly referred to as the Larut sucker frog, is a species of frog native to the Malay Peninsula. Its range extends from the southernmost parts of Thailand down into Malaysia. This species is well-adapted to its specific environment, making it a notable inhabitant of its native region.
Description and Adaptations
The physical characteristics of Amolops larutensis include distinct sexual dimorphism in size, with males measuring between 35–45 mm in snout-to-vent length and females being considerably larger, reaching 53–75 mm. A defining feature of this frog is the presence of large adhesive discs on the tips of its fingers and smaller ones on its toes. These specialized pads are crucial for its survival, enabling it to firmly grip surfaces in its challenging habitat. The frog's skin is granular, and its upper body typically displays a pale yellowish-green hue overlaid with dark blotches, while its underside is white.
Habitat and Ecology
Amolops larutensis is a common and abundant species, predominantly found in and along fast-flowing, clear-water forest streams. It inhabits rocky substrates, including boulders and bedrock, within both lowland and highland areas. The species is so prevalent in these environments that it may be the most common frog found in forest boulder streams throughout the Malay Peninsula. Its tadpoles possess large ventral suckers, which they utilize to adhere to rocky surfaces, an essential adaptation for surviving in strong currents.
Conservation Status
The International Union for Conservation of Nature (IUCN) does not currently consider Amolops larutensis to be a threatened species, indicating a stable population within its natural range.
