These gentle giants are famous for their singing abilities -- belting out seductive ballads to attract mates or to challenge other would-be suitors. But they also have other talents. Their unique hunting skill, called bubblenet feeding, involves a group of humpbacks working together to capture schools of herring. Each whale has a particular role in the process: One whale swims in a circle while blowing bubbles under a school of herring. When the bubbles rise, the school of herring can not escape and form into a tight ball in the center. Other whales vocalize -- grunting or screaming -- to scare the herring to the surface. The whales then rise with their mouths wide open to capture large amounts of fish.
