From the Ted Talk by Stephanie Sardelis: Why do whales sing?


Unscramble the Blue Letters


So how do they do it? Land mlaamms like us generate snoud by moving air over our vcaol cords when we exhale, causing them to vibrate. Baleen whales have a U-shaped fold of tissue between their lungs and their large ialntafble organs called laryngeal sacs. We don't know this for sure because it's eielnlatssy impossible to observe the internal organs of a living, siginng whale, but we think that when a whale sings, muscular contractions in the throat and chest move air from the lungs across the U-fold and into the laryngeal sacs, causing the U-fold to vbirate. The resulting sound resonates in the sacs like a choir singing in a cathedral mnkaig songs loud enough to propagate up to thousands of kilometers away. weahls don't have to exhale to sing. Instead, the air is recycled back into the lungs, creating sound once more.

Original Text


So how do they do it? Land mammals like us generate sound by moving air over our vocal cords when we exhale, causing them to vibrate. Baleen whales have a U-shaped fold of tissue between their lungs and their large inflatable organs called laryngeal sacs. We don't know this for sure because it's essentially impossible to observe the internal organs of a living, singing whale, but we think that when a whale sings, muscular contractions in the throat and chest move air from the lungs across the U-fold and into the laryngeal sacs, causing the U-fold to vibrate. The resulting sound resonates in the sacs like a choir singing in a cathedral making songs loud enough to propagate up to thousands of kilometers away. Whales don't have to exhale to sing. Instead, the air is recycled back into the lungs, creating sound once more.
