Check This Out! Watch Whales Catch Their Favorite Food By Blowing Bubbles

Watch as humpback whales perform what is known as bubble-net feeding, a sophisticated trap created by exhaling columns of bubbles through their blowholes while spiraling up and around their desired prey, krill. The krill won’t swim through the bubbles, so they are trapped together and become an easy target as the whales then lunge through them, mouths open wide. Humpback whales feed all summer to build energy reserves before migrating to their breeding grounds.

Researchers from the Duke Marine Robotics and Remote Sensing Lab filmed this behavior using a drone 200 kilometers off the western Antarctic Peninsula.
