Deep impact: gray seals clap underwater to communicate

In general, marine mammals such as whales, dolphins, and seals use calls to communicate with other individuals, and their calls are very diverse. Researchers have also learned that teaching teachers to sing songs will enable them to sing songs such as 'Star Wars Theme' and 'Glittering Stars.'

However, in a study newly announced by a research team of Monash University and Newcastle University on January 30, 2020, it was reported that `` grey seals 'applause' underwater and communicate with other individuals '' . It has not been confirmed that gray seals clapping underwater, but Ben Burville, a visiting researcher at the University of Newcastle, has been swimming with gray seals for 17 years, and as a result, it was finally possible to shoot applause of gray seals That

You can see how the seals actually “applause” underwater in the following movie.

In a movie taken by Burville in October 2017 while scuba diving around the Farn Islands , the sound of underwater is also recorded, and the muffled sound of a gray seal swimming around can be heard.

Suddenly, the two fins were struck with great power, and a loud “pan” sounded. This is the applause of the gray seal.

In addition, the gray seal stretches the two fins to the side of the body, making it for a while ...

Immediately the second applause was made.

In the end, Burville was able to shoot seven claps.

Researchers have heard sounds like applause while swimming with gray seals for a long time, but for many years they thought that it was noise such as noise caught by the microphone. Mr. Burville saw that the gray seals applauded, and for the first time he noticed that the sound heard underwater was due to the applause of the gray seals. 'The applause was incredibly large, and it was difficult to believe at first the sight I saw. How can seals clapping like this in water without the air compressed by the two fins?' Says Burville.

It has long been known that marine mammals other than seals make sounds by hitting the water with their bodies and tails, producing sounds like percussion instruments. However, this is an action performed by hitting the surface of the body with the whole body, one tail, or fins, and it is unusual to hit two fins in the water and make a sound.

'The discovery that seals applause may not be surprising,' said

David Hocking of Monash University, saying that seals applaud at zoos and aquariums. He pointed out that many people have seen it. On the other hand, 'But zoo creatures are often instructed to applaud to entertain people. The wild gray seals discovered this time are clap at their own will. ', Said the novelty of discovery.

The researchers believe that wild gray seals applaud, 'having the same purpose as gorilla drumming .' Drumming has the purpose of appealing to other animals to warn their strength and appealing to the breeding partner for their charm, but the applause of the gray seal is also performed during the breeding season, so the same purpose There is a high possibility.

'Applause appears to be an important social activity for gray seals, so disrupting it may affect reproduction and species survival,' the researchers noted. As it turned out that whales are communicating by barking, knowing the behavior of animals, just as it was found that human noise is harming whales, what kind of human behavior is harmful to animals The research team argued that they would know what to give.
