Anatomy and Functional Morphology of the Mysticete Rorqual Whale Larynx: Phonation Positions of the U‐Fold
International audience Many Mysticetes (baleen whales) are acoustically active marine mammals. This is epitomized by rorquals, and specifically male humpback whales (Megaptera novaeangliae) whose complex songs comprise a wide range of vocalizations. The sound production mechanism of odontocetes (too...
