Resumen

Hoplias malabaricus (Bloch, 1794) is a Neotropical predatory fish known for its generalist diet, which includes opportunistic consumption of amphibians. Leptodactylus paraná is a recently described anuran with a restricted distribution in the Atlantic Forest. This study reports the first record of predation by H. malabaricus on L. paraná, observed in a eutrophic stream in the municipality of Praia Grande, state of São Paulo, Brazil. We describe the interaction and discuss how environmental characteristics of the site may have facilitated the observation of the event. This record contributes to the knowledge of the natural history of both species and reinforces the opportunistic feeding behavior of H. malabaricus.
