Abstract

Amphibians in terms of their predatory behaviour depend mainly upon the ambush technique.  Other than predation, amphibians have also been recorded to scavenge to acquire food resources.  This is an opportunistic observation of predatory behaviour of an amphibian species (Euphlyctis sp.) on the foam nest of another species (Polypedates sp.).  The behaviour was recorded during a routine field sampling, which is broadly written in the body of this write up.  Such an observation to our knowledge has not been reported earlier.  This observation will have implications in terms of amphibian ecology, behavioural studies, and also diversity studies in the range of foraging behaviour.
