Summary
How do you cry out "Help!" in caiman language? This is the question Thierry Aubin and Nicolas Mathevon, bioacousticians at the CNRS ask themselves. We travel with them to the marshy plains of Venezuela, where they engage sometimes in sporting experiments: capturing young caimans, recording their cries of distress, then broadcasting them to observe the mothers' reactions. The results obtained provide a better understanding of the evolution of sound communication in the animal world.
