Abstract

Cephalopod remains from the stomachs of three striped dolphins (Stenella coeruleoalba) and two Risso’s dolphins (Grampus griseus) taken as bycatch in= the swordfish fishing in the eastern Mediterranean Sea off Turkish coast were examined. Totally 478 lower beaks were identified as belonging to 14 cephalopod species. For the striped dolphins, A b r a l i a v e r a n y i was the m= ost common prey (51.2% of all the beaks found in this species), followed by <= span style=3D'font-style:italic'>Onychoteuthis banksii and Heteroteuthis dispar. For the Risso&#= 8217;s dolphins, Histioteuthis re v e r s a was the most common species (60.9%) and all the other species shared less than 1= 0% of all the beaks found. In the stomachs of the striped dolphins, there were remains of some fish and shrimps, while only cephalopod remains were detecte= d in those of the Risso’s dolphins. Most prey species were oceanic cephalopods, with wide vertical distribution and diurnal movement. Many of t= he cephalopods identified in the diet of these dolphins are bioluminescent suggesting that these dolphins use bioluminescence as a target when feeding= on cephalopods.
