Rorqual whale (Balaenopteridae) surface lunge‐feeding behaviors: Standardized classification, repertoire diversity, and evolutionary analyses
Abstract Rorqual whales (Family: Balaenopteridae) are the world's largest predators and sometimes feed near or at the sea surface on small schooling prey. Most rorquals capture prey using a behavioral process known as lunge‐feeding that, when occurring at the surface, often exposes the mouth an...
