Amolops marmoratus

Amolops marmoratus, the marbled sucker frog or marbled cascade frog, is a ranid frog. The cached account says it is known with certainty only from Myanmar and likely northern Thailand, though it may occur more widely, and that the status of many populations formerly assigned to it is uncertain. Its Indian listing here rests on the species database (Wikipedia, general species account).

Males and females differ greatly in size: males grow to 38-48 mm in snout-vent length and females to 70-79 mm, and it is a relatively small species within Amolops. As typical for the genus, it lives near fast-flowing mountain streams (Wikipedia, general species account).
