Groundbreaking Footage Shows Humpback Whales Creating Bubble Nets To Trap Prey (Video)

During the summer feeding period, about 3,000 humpback whales visit Alaska, while up to 10,000 of them are in Hawaii for the winter breeding period. When leaving their foraging grounds and migrating 3,000 miles, the whales stop feeding until their return several months later. Females in Hawaii use large amounts of energy when giving birth, lactating and raising their offspring before migrating back to their foraging grounds.
