Bubblenet-feeding Humpback Whales in Antarctica. Bubblenet feeding by Humpback Whales is a very sophisticated, co-operative, group-based approach to feeding. Vertical walls of bubbles are created to trap prey for easier feeding. In the waters (Aquirre Passage and Paradise Harbour) near the Gabrial Gonzales Videla base (Chilean) on the Antarctic Peninsular, we were fortunate to see these whales bubblenet-feeding in calm waters. This was made even better by the stunning backdrops of glaciers and moutains. An amazing spectacle.
