Common Lazy Toad

The Common Lazy Toad (<em>Oreolalax major</em>) is an amphibian in the family Megophryidae, classified as Least Concern on the IUCN Red List. The species typically inhabits freshwater habitats, moist forests, and wetlands, favoring cool, humid environments associated with mountain streams and adjacent riparian vegetation. As a member of the family Megophryidae, it is adapted to fast-flowing, clear mountain streams where larvae typically develop among leaf litter and gravel on the stream bed. The Common Lazy Toad is generally associated with the highland and montane zones of its range, relying on intact forest cover and unpolluted water bodies for reproduction and larval development. Its Least Concern status reflects an assessment of stable population trends, though like many amphibians it may be sensitive to changes in water quality, habitat loss, and emerging infectious diseases such as chytridiomycosis. Biological traits of this species remain poorly documented in the scientific literature.
