A humpback whale fishes with a very special net. It doesn’t weave its net from rope, but from air bubbles instead. Called “bubble-net feeding,” this method involves blowing bubbles in a tight, spiraling pattern underneath a school of fish. The rising bubbles surround the fish in a tube-shaped corral. When the tube is complete, the whale swims straight up, through its center. With bubbles to all sides and a hungry whale below, the confused fish try to escape by swimming upwards too. They have no other direction to swim towards.
Imagine yourself in a nearby boat: You’d see a circle of bubbles form on the water’s surface, then the sudden flash as scores of herring break the surface. Before they can fall back, the huge whale lifts out of the water beneath them, snaps its jaws shut, then crashes back into the ocean to digest its meal. Hundreds to thousands of fish in a single catch!
