It is believed that fish do not know how to talk, that is, they do not make sounds for interspecific and intraspecific communication. We decided to check if this is really so.
This myth has existed for more than one hundred years. Phraseologisms went from him "Him like a fish" And "Silent like fish about ice". It was used in the names books About marine mammals and films. Users Interested, are all the fish dumb, on popular services questions And answers.
Pisces, indeed, do not speak as people or animals that live on land do it, since they do not have vocal cords. Nevertheless, scientists They saythat fish are quite sociable creatures. They can To make various sounds with the help of gills, fins or teeth: it can be low -frequency pops, croaking, gurgling, growl. During the 2014 study, American scientists recorded about 80 different sound signals made by fish. This was mainly happening during a fight, courtship, feeding or protection of nests.
Researchers They saythat it is by sounds that fish are guided by, where they should settle. Scientists were even going to use the recording of such sounds to attract marine mammals to a large barrier reef, saving him thus from gradual extinction. By the way, by sounds that make marine invertebrates and fish, scientists can determine the state of coral reefs: Low -frequency Sounds say that everything is in order High -frequency - testify to problems.
Scientists of the University of Cornell found outthat fish are able to communicate with the help of sounds for 155 million years - their "speech" originated approximately the same when mammals on land. And during this time it changed 33 times - which means that it was important in the evolutionary sense. One of the authors of this study, Aaron Rice, has been led for 20 years database With audio recordings of fishing. He claimsthat, like people, fish basically worries food and sex - they are talking about this. Although the love songs of fish are not at all like the vocals of Taylor Swift. For example, fish-taber-thables are more likely remind Growing wipers (biologists Shared audio recordings of these sounds). And in 2008 in Florida was incident, when the locals complained about the constant noise of repair work, which turned out to be a sound made by a bard fish in the wedding period.
Despite the fact that it is rare to be heard from the surface of the water of the fish, to dive to a large barrier reef in order to listen to them, it is not necessary: researchers-enthusiasts already Recorded Fish conversations using underwater recording devices and posted them on the Internet.
Moreover, scientists They were able Fix even choral singing in fish. Researchers installed two recording devices on the west coast of Australia: one at the very shore, and the other at a distance of 21 km. They tracked the sounds for 18 months and recorded both separate voice signals and entire choirs in which these sounds were formed. It turned out that at a certain time of the year (for example, in the rainy seasons), fish are most talkative.
Thus, in the usual sense, the fish really cannot talk, since they do not have the speech apparatus necessary for this. But at the same time, many of their species make a variety of sounds with the help of different parts of their body and may well communicate, and they do it as long as mammals.
