The Montane Chorus Frog (Oreophryne monticola) is a small arboreal frog belonging to the family Microhylidae. It is native to montane forests of Indonesia, particularly on islands such as Sulawesi. Adults are typically less than 30 mm in length, with a stocky body and relatively short limbs. The coloration ranges from light brown to grayish, often with darker blotches or mottled patterns that help with camouflage against tree bark and leaf litter. The head is broad with a rounded snout, and the fingers and toes have expanded discs adapted for climbing.
TADPOLE does not have a free-swimming tadpole stage. It exhibits direct development, meaning the eggs hatch directly into miniature frogs. The embryos develop fully within the eggs, which are usually laid in moist terrestrial or arboreal sites, such as leaf axils or mossy vegetation.
Aggressive or Danger to Human? This species is not aggressive and harmless to humans. It is a shy, nocturnal frog that avoids confrontation and poses no danger.
Population Status: The Montane Chorus Frog is currently listed as Endangered globally (Source: IUCN Red List).
Habitat and Habits: This species inhabits montane and submontane forests, typically at elevations between 1,000–2,000 meters above sea level. It prefers moist environments with abundant vegetation, often perching on shrubs, tree trunks, or under moss-covered surfaces. The Montane Chorus Frog is nocturnal and insectivorous, feeding on small invertebrates. Its call is a short, soft trill or chirp, usually heard during humid nights or after rain. Breeding likely occurs in moist microhabitats, taking advantage of the wet season to ensure successful egg development.
