Describe the feeding behavior and ecological importance of the humpback whale’s bubble-net feeding technique, and how does this behavior impact the marine food web?

Humpback whales (Megaptera novaeangliae) use a technique called bubble-net feeding to trap and concentrate schools of small fish or krill. The whales swim in a circle while releasing bubbles, creating a net-like barrier that traps prey in a dense area. The whales then swim through the bubble net with their mouths open to capture large quantities of food. This technique not only allows humpbacks to efficiently feed but also impacts the marine food web by influencing the distribution and abundance of prey species.
