Scientists have recently made a significant breakthrough in understanding how whales produce their unique underwater songs. A groundbreaking study published in the journal Nature has revealed that baleen whales, including humpbacks, possess a distinct laryngeal structure that enables them to create these haunting sounds. This unique voice box features a long, rigid U-shaped cylinder that facilitates massive air flows during breathing.
Researchers discovered that baleen whales have evolved specialized nasal and oral plugs within their respiratory tract to protect their airways while breathing and feeding. Additionally, the whales have air sacs that allow them to recycle air while producing vocalizations.
