Humpback whales (Megaptera novaeangliae) are well known to form closed lings of bubbles to encircle and concentrate prey for more efficient feeding - both alone and in cooperative groups. Similar behavior has been documented in Bryde's whales (Balaenoptera brydei), but the extent to which bubbles are used for prey manipulation is less understood for other rorqual species, including blue (Balaenoptera mussculus), fin (Balaenoptera physalus), and minke (Balaenoptera acutorostrata) whales. While not quantitatively analyzed, the qualitative evidence of regular and perhaps exclusive left-lateral lunge-feeding (LLF) in combination with bubbles contrasts with findings of previous studies that showed a strong preference for RLL feeding in fin whales.
