Lying between the mouth and the trachea, it is a cavity associated with the larynx and can serve as an air reservoir. The laryngeal sac is surrounded by muscles and its volume can change based on the contraction or relaxation of these muscles.\u00a0There are two hypotheses regarding the function of this structure, which is still the subject of debate amongst scientists.<\/p>\n<h2>Soundbox<\/h2>\n<p>In baleen whales, the laryngeal sac might help to produce and amplify sounds. Changes in the sac\u2019s volume make it possible to alter the nature of the sounds produced. This hypothesis is supported by a similar structure found in frogs that allows them to produce their characteristic songs. Monkeys are also thought to use their laryngeal sac to howl without hyperventilating. This animation by Stephanie Sardelis and Boniato Studio on whale songs present the hypothetical mechanism of the laryngeal sac in sound production in humpback whales.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The laryngeal sac is a structure found in baleen whales, but also in many other mammals, including primates (but not humans!).
