Acoustic communication in crocodiles
Year: 2012
Type: conference-paper
Abstract: All species of crocodiles are known for their ability to produce sounds in several communication contexts. However and despite the importance of sound communication in the life of crocodilians, knowledge about their vocal world remains superficial. This paper aims to present recent advances in our understanding of crocodile bioacoustics. Through experiments both in the laboratory and the field , we have brought evidence of the biological role of young crocodilian calls, especially at hatching time and later on during mother-offspring interactions. By analyzing the acoustic structure of emitted signals and by using playback experiments with modified signals, it has also been possible to identify the relevant acoustic cues that elicit behavioral responses of offspring and mothers. It is now time to do more comparative research among crocodilian species.
