Defensive behaviors in Pleurodema borellii (Anura: Leptodactylidae) from northwest Argentina

Anurans are common prey for several vertebrates and also invertebrates. In response to this predatory pressure, they exhibit various defensive behaviors. In this work we report liquid cloacal discharge, body inflation, stiff-legged posture and body vibration performed by Pleurodema borellii from San Miguel de Tucumán, northwest of Argentina. These multiple defensive beha-viors performed together can hinder or disrupt the predator’s action more efficiently.
