Bubble net

From Openwaterpedia

noun - Bubble-net feeding is a unique and complex feeding behavior engaged in by humpback whales and Bryde's whales. It is one of the few surface feeding behaviors that humpback whales often do in groups. The group size can range from a minimum of two or three whales participating and up to sixty at one time. Whales can also perform a similar method of surface feeding called lunge feeding, but this is done solo.

Humpback whales are migratory and only eat during half the year. They will typically spend the summer months (May through September) in feeding grounds with cooler waters that they return to every year. They have been documented feeding in areas such as Southeast Alaska and off the coast of Antarctica. During the other half of the year, humpbacks will spend time in their breeding grounds where they do not eat at all. During their feeding season humpback whales will actively feed for up to twenty-two hours a day. They do this so they can store enough fat reserves to live through their breeding season.
