While they may lack some of the melodic qualities of birds or whales, there are almost 1,000 species of fish that use sounds to communicate, and possibly many more.
Yet, despite nearly 150 years of contemporary scientific research into fish sound production, there was no global inventory of fish species known to make sounds. Until now. Fish are one of the largest groups of sound-producing vertebrates, with speculated sound production abilities in thousands of the 34,000 fish species globally.
Fish also have a wide diversity of mechanisms for their sound production. Instead of vocal cords, fish may have adapted bony structures that they can rub or click together, while others use their swim bladder like a drum. Some fish even make sounds by expelling air out of their backsides. Yes, communication through “fish farting.”
