Humpback Whale Anatomy and Behavior

The video explores how humpback whales achieve remarkable speed and acceleration. Contrary to previous beliefs, they only need to dive about 20 feet to gain speed. This is possible due to a powerful muscle called the peduncle, which generates immense thrust. The peduncle requires a large supply of oxygen-rich blood, provided by the whale's massive heart. Additionally, the whale flaps its flippers like a bird to aid in takeoff.
