Humpback whales use a special hunting technique known as bubble net feeding. Whales, either individually or in a group, swim in a shrinking circle, blowing bubbles below a school of prey. The shrinking ring of bubbles encircles the school and confines it in an ever-smaller cylinder. The fish trapped in the middle of the bubble net are then eaten in one go as whales rise from below with an open mouth.
