Humpback whale

 A group of Humpback whales will locate a large group of small fishes and then blow bubbles from their blowholes as they circle toward the surface. The ring of bubbles forms a “bubble-net” which the fishes and or krill perceive as solid.  The fishes are compressed and the multiple whales then rise in unison to the surface inside the “bubble net” with their mouths open and their pleats expanded for a maxium catch of herring, caplin or sandlance.

The water is expelled through their comb-like baleen (made of keratin) while their tongue sweeps the fishes down their throat.

Waving good-bye with their flukes elevated and preparing a new bubble-net.

Note: Flippering:  When a Humpback raises one or both flippers out of the water and slaps them against the water (see above).

Kickfeeding: The Humpback raises and slams his rear flukes against the water surface to stun fishes and then dives and surfaces to engulf the stunned fishes.

REMARKS Individual Humpbacks may lunge into schools of fishes or krill under water.
