How does a whale make scary sounds? Scientists have learned this secret.

Scientists: Have discovered the secret of how giant whales in the ocean make eerie and complex song like sounds.

Humpbacks and other large whales have a special 'voice box' that helps them make underwater sounds or sing.

The discovery, published in the journal Nature. Also reveals why the noise we make in the ocean is so painful for these whales.

The song or sound of whales is subtle and gets louder with the sound made by ships.


Sound is very important for their survival as it is the only way they can find each other in the sea to mate. Explains Professor Koen Allemans of the University of Southern Denmark, who led the study. are.


There are 14 species of baleen whales, including the pleo humpback, right, minke and gray whales. Instead of teeth, these whales have a large bone-like plate called a bullen in their mouth. This enables them to swallow large quantities of small fish and food in the sea. That is why they are called ballen wheels.


Until now, it was a mystery how these whales make these complex or terrifying sounds. Professor Elmans says he is "extremely pleased" to have resolved the issue.


He and his colleagues conducted experiments using larynxes, or 'voice boxes', which were carefully removed from the carcasses of three whales, a minke, a humpback and a sea whale. He then blew air through the voice box to produce sound.


In humans, sound is produced when air passes through the vocal folds in the throat and vibrates.

This vocalization in animals is done by recycling air, which prevents them from getting water in their throats.

The researchers generated the sounds through computer models, which showed that the sounds of baleen whales are subtle but become louder when combined with the noise produced by ships.


Professor Elmans says they can't raise their voices as loud as they sing to avoid our noise.


Their research also shows how the noise we make in the ocean can prevent whales from communicating with other whales over long distances. This could be important for the conservation of humpbacks, blue whales and other endangered whales.

It also answers questions about the strange song-like sounds that researchers have been searching for for decades, which some sailors have attributed to spirits or sea giants.


Oregon State whale communication expert Dr. Kate Safford called the research significant.


Sounding and hearing are the most important senses for marine mammals," he told the BBC. Therefore, the study of how these sounds are produced is very important for further research in this field.


In this study, the researchers also provide an evolutionary picture of how whales came from land to the oceans and the adaptations that made it possible for them to communicate underwater.


The way toothed whales make sounds is better understood because they are easier to study. These marine mammals, which include dolphins, orcas, sperm whales and porpoises, breathe air through a special structure in their nostrils.


Dr Alan Garland, from the Marine Mammal Research Unit at the University of St Andrews, says: 'I've always thought that baleen whales, particularly humpbacks, on which my research focuses, make a variety of sounds.'


Researching large whales is difficult, and trying to figure out how they make sounds by wading when you can't see them is even harder. So the researchers have done a great job in this regard.


Dr Stafford added that while the ability of whales to produce complex vocalizations is remarkable, it also highlights how special these animals are.
