Australian long-finned pilot whales (Globicephala melas) emit stereotypical, variable, biphonic, multi-component, and sequenced vocalisations, similar to those recorded in the northern hemisphere
Abstract While in the northern hemisphere, many studies have been conducted on the vocal repertoire of long-finned pilot whales ( Globicephala melas ), no such study has been conducted in the southern hemisphere. Presented here, is the first study on the vocalisations of long-finned pilot whales alo...
