Anurans have evolved a wide array of defensive strategies to augment their survival probability when attacked by predators. Herein, we report a predation attempt of Helicops angulatus (Linnaeus, 1758) (Dipsadidae: Xenodontinae) upon Hypsiboas boans (Linnaeus, 1824) (Anura: Hylidae), in Central Amazon, Brazil and present details on the defensive behavior exhibit by the attacked frog. This note reports the first observed trophic interaction between both species and the first evidence of distress calls emitted by H. boans upon attack by a natural predator.
