Bubble-net feeding is a unique and complex feeding behavior engaged in by humpback whales (Megaptera novaeangliae)[1] and Bryde's whales in Gulf of Tosa (jp), Japan.[2][3] It is one of the few surface feeding behaviors that humpback whales are known to engage in.[4] This type of feeding is often done in groups.[4] The group size can range from a minimum of two or three whales participating and up to sixty at one time.[5] Whales can also perform a similar method of surface feeding called lunge feeding but this is done solo.[4]
