Abstract
We report in situ and ex situ observations on interand intra-specific predatory behaviour in tadpoles of the common Asian toad Duttaphrynus melanostictus . In situ D. melanostictus tadpoles feed on conspecific eggs, tadpoles of various developmental stages and adult carrion as well as dead heterospecific ( Fejervarya orissaensis and Euphlyctis cyanophlyctis ) tadpoles. Predation of weak, feebly swimming larvae and metamorphs in seminatural habitats under optimum conditions seems to be an opportunistic behaviour and diet enrichment, which needs additional support. Our observations support earlier reports indicating gradual desiccation, food shortage, competition and density as the probable factors of predation in temporary habitats.
