☆ Mystery of whale song unraveled by scientists, study says
  + stars: | 2024-02-22 | by ( Amarachi Orie | ) edition.cnn.com   time to read: +6 min
How baleen whales, which include humpback whales, are able to sing underwater has eluded scientists since whale songs were first discovered more than 50 years ago. A baleen whale’s larynx is shaped differently from other mammals. This structural adaptation allows the leviathan to breathe massive amounts of air in and out when they go to the surface, according to the study. Air sacs also evolved in a way that may allow a baleen whale to recycle air while creating vocal sounds, according to researchers. This means that most boating noises mask calls between baleen whales, reducing the distance over which they can communicate.

☆ For toothed whales, sound production is all in the nose
  + stars: | 2023-03-02 | by ( Will Dunham | ) www.reuters.com   time to read: +4 min
Researchers on Thursday offered a comprehensive explanation for sound production by toothed whales - loud clicks for echolocation, and softer burst pulses and whistles for communication. The researchers used sound-recording tags on sperm whales, false killer whales and bottlenosed dolphins to study sound production in the wild. The sounds made by toothed whales differ from the haunting "singing" by filter-feeding baleen whales. "Toothed whales don't sing like baleen whales," Madsen said. During the course of evolution, toothed whales have lost their vocal folds, but evolved an entirely new set of sound sources in the nose."
☆ Whales use a sound similar to Kim Kardashian's 'vocal fry' to hunt deep sea prey, say scientists

Toothed whales can use vocal registers like humans to communicate and hunt. Like Kim Kardashian, whales have a "vocal fry" which can be used to find prey in deep sea. This gives them access to falsetto, which allows them to make their high-pitched whistles, and the chesty, vocal fry range, which is how they make echolocation. Christian B. Christensen, Aarhus UniversityAn affectation that shaped toothed whales' evolutionTeglberg and Elemans say this has very much influenced the way dolphins, orcas, and other toothed whales evolved a "Mona Lisa" fixed smile on their face. "While vocal fry may be controversial in humans and may be perceived as everything from annoying toauthoritative, it doubtlessly made toothed whales an evolutionary success story", Elemans adds.
☆ Bats use same techniques as death metal singers to vocalize, study finds
  + stars: | 2022-11-29 | by ( Zoe Sottile | ) edition.cnn.com   time to read: +4 min
CNN —Death metal fans might just have a new animal mascot. Some bats use the same vocal structures as death metal singers to make their unique vocalizations, a new study has found. This allowed the scientists to directly observe the vocal membranes and ventricular folds, also called “false vocal folds,” vibrating at different frequencies. These are “the first direct observations” of these vocal structures in Daubenton’s bats, the researchers said. Ventricular folds, or false vocal folds, are located on top of the true vocal cords.
