Quite often we will observe one humpback whale following the shoreline with the intense purpose of feeding. Every 200 to 300 meters the whale will take a few shallow breaths, then arch its back to prepare for a deep dive. Our last sight is that of the tail fluke. Often others will join this whale and they will cooperate in an intriguing feeding strategy referred to as Bubble Net Feeding. The whales will dive below a shoal of prey, approximately 50 meters, and then slowly they begin a spiral dance towards the surface, blowing bubbles in a circular motion. On the surface you will actually see a circle of bubbles form as the whales move in this spiral formation. The purpose of the bubbles is to congregate prey and force them towards the surface near the center of this circle. What you will witness next is an explosion of air as these whales surface in the center of this circle of bubbles, their mouths gaping wide open.
