If you don’t have nets to use then you can always make your own. This is what humpback whales do when they sense an opportunity to enjoy a feast and this behavior is only seen in Southeast Alaska where this rare and remarkable footage was taken by
AkXpro Productions. Other whales do use bubble feeding but this method is unique to the Alaskan whales. Anywhere from four to twenty whales will join in with the hunt. One will release a ring of bubbles from its blowhole beneath the herring. This curtain of bubbles acts as a wall which keeps the fish inside it. Then another whale will produce vocalizations (which we can’t hear in this video, of course!) which makes the herring squeeze together in tight balls.
Then the whales lunge in unison. Breaking the surface simultaneously with their mouths wide open, then roll over and down. This captures as many fish as possible as well as forcing the water they take in out through their baleen plates. With the water forced out they can then gulp down their prey. Altogether, pretty amazing!
