What sound does shark make? Scientists record clicks on the podium shark

For decades, sharks Silent creatures were considered. Unlike other fish, they lack Holds like a bladderCommonly used for Sound production; However, new A study led by Oakland University in New Zealand It was published in the Journal of Open Sciences for the Royal Society, Ha Documenting for the first time to a penny a job voice Activity.

The result: “Click, Click” under the water

The hero of the novel.Neozylaland, which is about 1.5 meters long.

The team of scientists noted that this shark could produce a sound similar to the electric click, described as “click, click”.

Marina Caroline Nider, a researcher at the Woods Hall Institute for Oceanic Sciences and the main author of the study, explained. The result was completely transverse.

Nabadi said: “I thought:” My God, I think they are making some noise, “remembering the moment when he heard the click first while watching the sharks in the tank in 2021.

How does this sound happen?

According to the notes, the sound appears to occur in sharks Tamps or topicsThis indicates that clicking can be a response to tension. Researchers suspect that noise can be linked With a shark shieldAlthough there is no final confirmation of the accurate mechanism.

team Use submarine registration equipment To pick up the sound and discover that the sharks were not emitted from noise when swimming freely, which enhances the hypothesis Chanks is not part of their connections Regular, but one A possible defensive reaction.

A discovery can change the perception of sharks

To date, sharks have been filmed as silent predators, both in cinema and scientific publishing. from Movies like Shark to SharknadoHis absence of sound has strengthened his image as hidden and frightening hunters.

But as NIEDER indicates, more than 500 sharks live in the world’s oceans, many of which are small and weak, such as platform shark.

The researcher said: “Many of these types are similar to shark a platform: small background fish, which they devour both humans and humans.”

Future effects

Discovery opens a new line of research on biomedes in sharks, a slightly explored field. He expects my Nabadi This discovery motivates scientists to study more Exactly how and why sharks can generate sounds, as well as The effect of this on their behavior and their survival.

He concluded by saying: “I hope this will raise the curiosity of people about sharks and sound – unless they think before – and people may encourage people to listen to sharks in their natural environment.”

The team plans to continue your research Determine whether other types of sharks also emit sounds What is the function that can have this behavior within its ecological systems.
