Are the fish really silent?

There is such an expression "dumb as a fish." Indeed, most people are convinced that fish are extremely silent creatures who generally do not know how to communicate with each other using sounds.

True, such an opinion is not shared by all, and, for example, such a classic of Russian literature as Kuprin, on the contrary, was sure that the fish were able to talk to each other. He even warned the fishermen not to let the caught fish back into the water, so that it would not notify its relatives. For most people, this opinion of the writer sounds like an absurdity, but let's not determine in advance who is right and who is not and try to figure it out on our own.

During World War II, there was an incident that puzzled many sailors. The fact was that someone constantly blew acoustic mines tuned to the noise of approaching large watercraft.

Special vehicles and mine torpedoes and even specially trained suicide bombers were suspected. However, it turned out that these saboteurs were not people, but fish. Moreover, these were not trained fish like dolphins, but ordinary fish capable of making sounds of sufficient strength to power a mine.

It seems that those scientists who invented acoustic mines, although they dealt with the sea, albeit in such a barbaric form, did not really imagine the life of its inhabitants and were completely and completely dominated by the prejudice of fish mute. As the subsequent fate of their invention showed, they were infinitely far from the true state of affairs.

The sounds of the underwater inhabitants of our ear are barely audible.

As is known from the laws of physics, under water, sound travels at a speed that is five times faster than the speed of propagation in air! And it would be very strange if the inhabitants of the underwater depths would not use this property of the water world as an exchange of information.

As acoustic studies of marine spaces show, in fish places there is a real buzz, where they make noise just like in a bazaar.

Few people have heard giants such as catfish popping. It is hard to imagine that such a powerful, and seemingly more than serious fish, can be so talkative. However, this is true. Soma are rare balabol.

They can even be heard without any special equipment. For example, one of the greatest scientists of all time and evolutionary theory author Charles Darwin heard catfish screaming as he strolled along the banks of the South American Uruguay River.

Soma - a rare underwater "balabol".

By the way, not only catfish, but fish in general, are great chat lovers. And I must say that this trait, unlike the human one, is not at all groundless. For example, carps warn their flock of impending danger with a series of special cracks that they immediately recognize. But river perches, on the contrary, crack when they drive the fry on a hunt.

Of course, the range of sounds available to fish with wealth does not shine. This is largely due to the fact that in the process of evolution they did not form voice resonators. Apparently they did not need them, and they coped well without them. Or maybe there simply weren’t such mutations in their evolutionary history, and it’s possible that fish resonators will appear someday. However, be that as it may in the future, so far the fish are noisy as they can - to the best of the abilities gifted to them by nature.

River perches make rattling sounds, driving the fry on the hunt.

Some fish make sounds using a swimming bladder, others have adapted scales for these purposes, third gill covers (this is still all right), and some even scream with fins. And that's not all! For example, carps make a specific crack when they grind their teeth located deep in their throats!

If you go down deeper into the depths of the deep sea, then you can also hear a lot of very interesting things there. For example, divers during their dives clearly distinguish grunts. However, it would be naive to look around, expecting to see drowning pigs, since several species of fish that can make such grunts can be detected at once in sea waters. Among these, you can find angel fish, which, as it turned out, has far from angelic vocals, and sea dogs, which, judging by the sounds, prefer far from barking.

Angelfish - the inhabitants of the depths with completely non-angelic vocals.

Oddly enough, representatives of the goby family differ in a very rich sound palette.

It would seem like a completely ordinary fish, whose fate is to lie on a shelf of the cheapest canned goods in a tomato, but some bulls can scream and others creak. There are even gobies that are able to buzz no worse than an underwater bee.

Shouting, shouting and singing fish are dependent on the situation. For example, when a mackerel meets an individual of the opposite sex, it begins to quack like a duck, apparently with joy. But representatives of the family of pufferfish, as a rule, scream with fear. With a fright, pufferfish greatly inflate their bodies, which is accompanied by strange sounds that resemble a loud croaking. But their not-so-distant relative, the trigger fish, when they feel fright, tweet and whistle.

Trigger fish - chirping underwater inhabitants.

But who has the most intolerable vocals is a toad fish, which has developed such abilities that its cries make everyone who fell into the sight of its sonic gun become ill. This fish, leading a sedentary lifestyle, is a rare owner, and guards its territory with enviable jealousy. As soon as strangers peer into her possessions, she chases them away with such a deafening roar that they have no choice but to get out.

For comparison, we can say that the ship's siren has about the same power. And since the fish can not only talk, sing and scream, but also listen to the sound passages of their floating relatives, this tactic of the toad fish fully justifies itself.

The power of arias of toad fish is more than a hundred decibels.

From the foregoing, we can conclude that fish mute is not true and that in fact fish are as talkative as politicians before the election. However, to make such an unambiguous conclusion would also not be entirely true. Dumb fish still exist. Therefore, it would be more correct to say not “silent as a fish”, but “silent as a flounder” - these fish actually do not know how.
