Resumen

En este estudio, reportamos el primer caso documentado de depredación por parte de Leptodeira approximans sobre Hyloscirtus dispersus, un anuro hílido de distribución andino-amazónica, registrado en el sureste de Ecuador. Se observó a L. approximans capturando e intentando ingerir un ejemplar de H. dispersus mientras estaba posado en un arbusto bajo. Aunque la serpiente finalmente liberó a la rana —presumiblemente debido a la presencia de observadores—, el anuro presentó signos de hemorragia, posiblemente causados por el veneno del colúbrido.
