Potential mechanism of sound production in Oreochromis niloticus(Cichlidae) [PDF]
Journal of Experimental Biology, 2009 SUMMARY Although acoustic communication is an integral part of cichlid behaviour,its mechanism has never been identified before. In the present study, a combination of approaches was used to investigate the sound-producing mechanism of Oreochromis niloticus. Synchronisation of high-speed video data (500 frames s–1) and cineradiographies (
