- They found that baleen whales evolved to produce sound with the vibrations of specific internal structures in the larynx, that toothed whales do not have. These specialized structures in baleen whales allow for sound to be produced and air recycled, while preventing the whales from inhaling water.

Feb 23, 2024 · And the scientists found that baleen whales use airflow to vibrate tissue and produce sound very similar to how we humans do it.
Feb 21, 2024 · Studies of vocal production in baleen whales show that their larynx has evolved unique structures that enable their low-frequency vocalizations but limit their active communication range.
The researchers produced computer models of the sounds and showed that baleen whale song is restricted to a narrow frequency which overlaps with noise produced by shipping vessels.
Feb 22, 2024 · Now a team of researchers have discovered the structure used by baleen whales — a modified version of the larynx. Whales like humpbacks and blue whales are able to create powerful vocalizations...
Feb 22, 2024 · It is one of Earth's most haunting sounds — the "songs" of baleen whales like the humpback can be heard over vast distances in the watery realm. Scientists now think they have an idea about how these marine mammals do it, and it's something not seen in other animals: a specialised voice box.
