![]() ![]() ![]() Dolphins consumed ten prey species, including grey mullet ( Mugil cephalus) as the most representative by wet mass (33.4%). Here we combine stomach content analysis (SCA), nutritional composition of prey, a multidimensional nutritional niche framework (MNNF) and videography to provide a holistic dietary, nutritional, and behavioural assessment of the feeding association between dolphins and gannets in the Hauraki Gulf, New Zealand. However, a current lack of insight on nutritional strategies with respect to foraging behaviours of both species has until now, prevented any detailed understanding of this conspecific relationship. Prey detection and subsequent capture is considered a major hypothesis to explain feeding associations between common dolphins and Australasian gannets.
