How do marine mammals use sound when feeding?
” (continued) Toothed whales and baleen whales produce other sounds to increase their chances of success during feeding. Humpback whales have developed a feeding technique called bubble feeding. Bubble feeding involves one or a few whales blowing air from their blowhole while underwater. This produces sound as the bubbles form a cloud, curtain, or column that rises toward the surface. The bubbles trap the prey between the surface and the whales mouth. A bubble net is formed when the bubbles emitted by the whales form a ring and concentrate the prey inside. Both the sound and the bubbles work to concentrate prey so the humpback can capture more food per mouthful.
