Dear colleagues Me and my co-authors are pleased to share our latest publication. Pierry JC, Novelli MBS, Louzada CN, Moteiro-Filho ELA. Rings of Power: evidence of mud ring feeding performed by Guiana dolphins. Journal of the Marine Biological Association of the United Kingdom. 2024;104:e69. doi:10.1017/S002531542400078X AbstractTo capture prey more efficiently, cetaceans can display a wide range of foraging tactics to separate individual prey. Barrier feeding tactics are performed to restrict prey movements, using natural and non-natural barriers and some species can even create barriers with their own bodies. Mud ring feeding has been observed in bottlenose dolphins in Florida Bay and in Chetumal-Corozal Bay, were ring-maker dolphins create ring-shaped mud plumes to encircle fish schools. Here, we document for the first time Guiana dolphins performing the mud ring feeding behavior in the Cananéia estuarine system, in the southern portion of the state of São Paulo, Brazil. A total of 11 dolphins were recorded in four expeditions through aerial footage engaging in the behaviour. These findings expand our knowledge about the behavioural plasticity of the species and builds upon existing records of mud ring feeding behaviour in cetaceans.
