Amolops marmoratus
Amolops·Least Concern (as of 2004 assessment, may require further evaluation)
Amolops marmoratus, also known as the marbled sucker frog or Pegu torrent frog, is a species of ranid frog native to Asia, primarily found in Myanmar and potentially northern Thailand. It is characterized by significant sexual dimorphism, with females being considerably larger than males. This species is typically found inhabiting areas near fast-flowing mountain streams.
Key Facts
- ›Found in Myanmar and likely northern Thailand.
- ›Exhibits pronounced sexual dimorphism in size.
- ›Males reach a snout-vent length of 38–48 MM, while females reach 70–79 MM.
- ›Inhabits areas near fast-flowing mountain streams.
- ›The taxonomic status of many formerly assigned populations is uncertain.
- ›IUCN assessed the species as 'Least Concern' in 2004, though this may warrant further assessment.

About Amolops marmoratus
Amolops marmoratus, commonly known as the marbled sucker frog or Pegu torrent frog, is a species of frog belonging to the Ranidae family, found in Asia. Its precise distribution is a subject of ongoing taxonomic consideration, with confirmed sightings in Myanmar and likely presence in northern Thailand. The species is known for its distinct sexual dimorphism, a trait that significantly differentiates the size of males and females.
Description and Habitat
This species is relatively small within the Amolops genus. A key characteristic is the pronounced difference in size between sexes: males typically measure between 38–48 mm in snout-vent length, while females are considerably larger, ranging from 70–79 mm. This sexual dimorphism is a notable feature of Amolops marmoratus. As is typical for its genus, the frog inhabits environments near fast-flowing mountain streams, indicating a preference for clear, turbulent freshwater habitats.
Distribution and Conservation
While definitively known from Myanmar and likely present in northern Thailand, the taxonomic status of populations assigned to Amolops marmoratus in other regions, such as Bangladesh, Bhutan, China, India, and Nepal, remains uncertain. In a 2004 assessment, the International Union for Conservation of Nature (IUCN) classified Amolops marmoratus as 'Least Concern,' citing its wide distribution and presumed large population. However, the recognition of greater biodiversity within the species suggests that a re-evaluation of its conservation status may be warranted.

Amolops mantzorum
Amolops mantzorum, also known as the Sichuan torrent frog or Kangting sucker frog, is a species of frog native to Gansu, Sichuan, and Yunnan Provinces of China, with recent reports from Bhutan. It is an abundant species found in streams and small rivers within forest and shrubland habitats.
Amolops torrentis
The torrent sucker frog (Amolops torrentis) is a species of frog endemic to Hainan Island, China, found in streams and surrounding wetlands. It is distinguished by the presence of tarsal glands, a specific tympanum edge, and a tibio-tarsal articulation reaching beyond the snout. This species is characterized by its high-pitched mating calls, which females favor, and its skin glands can secrete toxins, offering a defense against predators.
