Abstract: The killer whale, despite being considered a single species, exhibits various ecotypes (genetically and ecologically distinct populations), that focus on a specific type of prey (Ford et al., 1998(Ford et al., , 2000;;Pitman et al., 2011;Pitman & Ensor, 2003;Saulitis et al., 2000).In the northwestern Pacific, killer whales comprise two ecotypes: residents or R-type (fish-eaters) and transients, also called Bigg's killer whales, or T-type (mammal-eaters) (Filatova et al., 2018(Filatova et al., , 2019;;Ismail et al., 2023).These ecotypes are frequently found in the same areas, but they do not engage in social activities and are reproductively isolated (Filatova, Borisova, et al., 2015;Foote et al., 2011;Morin et al., 2010).This isolation is linked to significant variations in their morphology (Baird & Stacey, 1988;Kotik et al., 2023), ecology (Bigg, 1987), behavior (Morton, 1990), acoustic communication (Deecke et al., 2005;Filatova, Fedutin, et al., 2015;
