Stomach contents of mass‐stranded short‐finned pilot whales ( Globicephala macrorhynchus ) from North Carolina
Abstract We examined the stomach contents of 27 short‐finned pilot whales ( Globicephala macrorhynchus) that mass stranded on the North Carolina coast on 15 January 2005. Eleven whales had prey parts in their forestomachs. We used frequency of occurrence and numerical abundance to assess the relativ...
