摘要

Direct development in amphibians bypassing interme-diary tadpole stage has behavioural evolutionary and ecological significance. This paper presents direct de-velopment in Philautus cf. leucorhinus, while comparing with other congeners of the WesternGhats. AMPHIBIANS exhibit remarkable variations in develop-ment from egg to adult. One such extreme modification is direct development, wherein free-swimming tadpole stage is completely eliminated and eggs hatch into baby frogs, resembling the adults except for their size. Species adapted completely to terrestrial living generally exhibit direct development. The advantage of being adapted to such development includes avoidance of predation, which is prevalent in aquatic media, parental care and more importantly, dependency on water body for development and complex metamorphic processes.
