humpback wahles have a varey divers diet but it mostly consets of Krill, fish (herring, salmon, and mackerel), plankton, and other small marine organisms (squid, crustaceans, and other small marine life). Humpback whales eat a lot evry day adult humpback whales are know to eat up to 1.5tons a day you might be wonering why they eat so much the reason is simple they are storing up fat so they can make a long journey through out the ochans to get to their breeding grounds and they rarly eat eny thing on the trip so they have to eat as much as they can befor they go to make a new genaration who will repeat the same proses eating as much as they can in the feeding grounds and then making a long and groling journey to the breeding grounds.
Bubble-net feeding is a complex, cooperative hunting technique where humpback whales dive below prey, such as krill or herring, and blow a circular curtain of bubbles that traps the fish. The bubbles act as a physical and visual barrier, concentrating the prey into a tight ball. The whales then lunge upward through the center with open mouths, consuming massive amounts of food in a single gulp.
