Did you know that some species of fish have teeth capable of producing musical sounds? The “singing” or “grinding” teeth of certain fish, such as the Parrotfish and the Bluefish, are used to communicate, attract mates, or defend territory through the production of unique sounds.

The mechanism behind fish teeth producing sounds involves the rapid grinding or rubbing of specialized dental structures known as pharyngeal teeth or pharyngeal jaws. These teeth are located in the throat or pharynx of the fish and are capable of producing a variety of noises, ranging from clicks and pops to grating sounds.
