Diet composition constitutes basic information on the natural history of the species. Despite the amount of data acquired in the last years, much remains to be known specially for geographically widespread species. Here we compiled the available dietary items of Leptodactylus vastus and report the first predation event upon Rupirana cardosoi by a juvenile L. vastus. The fact these species are syntopic in the region probably resulted in this novel predation event. Different from previous L. vastus predation observations, the specimens we observed do not present a striking difference in body size, but L. vastus was able to almost swallow L. cardosoi, coherent with findings that mouth size is related to prey selection in anurans. Also, our literature review showed that L. vastus is a generalist and opportunistic predator, that prey upon small vertebrates (Amphibia, Squamata, and Mammalia).

La composición de la dieta constituye información básica sobre la historia natural de la especie. A pesar de la cantidad de datos adquiridos en los últimos años, aún queda mucho por conocer, especialmente para especies geográficamente extendidas. Aquí compilamos los elementos dietéticos disponibles de Leptodactylus vastus y reportamos el primer evento de depredación de Rupirana cardosoi por un juvenil de L. vastus. El hecho de que estas especies sean sintópicas en la región probablemente resultó en este nuevo evento de depredación. A diferencia de las observaciones previas de depredación de L. vastus, los especímenes que observamos no presentan una diferencia notable en el tamaño corporal, pero L. vastus fue capaz de casi tragar R. cardosoi, en coherencia con los hallazgos de que el tamaño de la boca está relacionado con la selección de presas en los anuros. Además, nuestra revisión de la literatura mostró que L. vastus es un depredador generalista y oportunista, que se alimenta de pequeños vertebrados (Amphibia, Squamata y Mammalia).
