'What Does the Anemonefish Say?': Investigating <i>Amphiprion percula</i>'s Acoustic Behaviour. [PDF]
This study investigates the vocal behaviour of wild Amphiprion percula in Papua New Guinea, revealing that distinct acoustic signals correspond to specific social interactions and are influenced by behaviour and rank. The findings underscore the importance of in situ research for understanding fish communication and highlight potential disruptions from
