Sixteen recently metamorphosed and forty-seven mature frogs were captured and the stomach contents examined. In view of the more limited choice of available prey imposed upon the former, due to the smaller jaw span, it was decided to tabulate the contents separately.
Aposematic prey formed a substantial proportion of the diet.
Large numbers of flowers were recovered from several stomachs.
Specific choice of prey varied with the individual, and it was concluded that R. esculenta as a species is not selective.
In the natural habitat R. esculenta does not by choice leave the water to feed unless there are insufficient aquatic prey.
It was found that mature adult frogs showed cannibalistic tendencies and this, coupled with a thermotactic response, influenced their distribution within the habitat.
