The majesty of the oceans carries within it mysterious secrets, among which the captivating song of the whales stands out. A recent published study offers a unique look at this fascinating phenomenon, revealing a unique vocal mechanism housed in the larynx of these marine giants.
Mysticetes, these baleen cetaceans such as the blue whale or the rorqual, sing thanks to a complex system located in their larynx, evoking the functioning of the vocal cords of land mammals. Long unknown, this mechanism has been brought to light by a team of international researchers, marking a major advance in the understanding of these captivating songs.
Through experiments carried out on samples of the larynx of different species of mysticetes, scientists discovered the existence of unique laryngeal structures allowing the production of complex sounds. Indeed, these whales would be capable of emitting not one, but two sounds simultaneously, thanks to the ingenious use of a pad of fat located above the cartilaginous cords.
This find raises new questions about whale communication and language. How do these mammals manage to produce such complex and varied songs? For what purpose are these vocalizations used? Does cohabitation with maritime traffic disrupt their communication?
The haunting melodies of whales remain a mystery in many ways, testifying to the richness and diversity of the animal kingdom. Their song resonates in the heart of the oceans, recalling the beauty and fragility of these vast expanses of sea where so many wonders still remain to be discovered.
