Bubble-net feeding is a feeding behavior engaged in by humpback whales[1] and Bryde's whales.[2] It is one of the few surface feeding behaviors that humpback whales are known to engage in.[3] This type of feeding can be done alone or in groups with as many as twenty whales participating at once.[4] Whales can also perform a similar method of surface feeding called "lunge feeding".[3][4]
Humpback whales are migratory and only eat during half of the year.[5] During this feeding season humpback whales actively feed for up to twenty-two hours a day.[4] They do this so they can store enough fat reserves to live through their breeding season when they do not eat at all.[4] Humpback whales typically spend summer months in feeding grounds with cooler waters that they return to every year.[5] They have been documented feeding in areas such as Southeast Alaska and off the coast of Antarctica.[5]
