We live in a world of sound and color, and there are "birds", "beasts" and "swimming fish" in the surrounding living environment. "Two yellow orioles singing willows" means that flying birds not only "talk" but also sing very beautifully. In addition, we can also hear the "Golden Rooster Announcing" at the crack of dawn, and the cows "Moo... Moo". All this shows that not only can we talk, but many animals can also "talk".
So have you ever heard a goldfish "talk" in your home? Does that mean that the fish are all "dumb" and they can't speak?
Of course not!
We all know that sound is caused by the vibration of an object, and the fish is certainly no exception. But fish are not like us sound by the vibration of the vocal cords, its vocal methods are strange, some rely on the pressure of the fish maw, some rely on rubbing the throat teeth, and some rely on vibrating muscles...
Carp make a "grunting" sound when they are hooked, and Kangi eels make a "barking" sound, which is the sound of gas bursting through the tube of the swim bladder. The yellow fish and bass in the sea can make a "grunting" sound, and sometimes the big yellow fish can also make such a sound, which is the resonance of the vibration of the maw and its connected muscles. There is a fish called the bream, which can imitate the rooster's cry, and it is precisely because of this skill that people have given it another name, "sea chicken", and its sound is rubbed through the tongue and jaw. In addition, the sound of stingrays and catfish is produced by the friction of hard spines on their dorsal fins, pectoral fins and ventral fins, while various fish in the order Breame, such as scaly pufferfish, make sounds through the friction of the upper and lower throat teeth.

In addition, box puffers can make dog calls; drum fish can make a sound similar to drumming; fish can make a lot of sounds!
Since so many fish can "talk" and "sing", why is it so difficult for us to hear their calls?
This is because the density of water is 7500 times that of air, so the sound of fish swimming, the sound of gill caps closing, the loud sound of fish maws, and various friction sounds disappear without a trace in the medium of water. Therefore, if you want to hear the sound of the fish "chatting" and "singing", you must use a certain instrument - hydrophone. Imagine if we listened to sounds from underwater through an instrument like this, then we would definitely feel a grand symphony.
