Fish can definitely talk
They rub their bones together, making sounds that are audible with the aid of their swim bladder, or otherwise they can even communicate by emitting air from their anus.Fish can definitely talk.
CORALLI has reported about this strange means of communication in herrings. People think that fish cannot talk especially because the majority of them produces infrasounds, which the human ear is incapable of hearing as their frequencies are too low. The first recording of sounds made by pomacentrids, which remind of a creaking door, was made back in 1930, but the mechanism that produces them has remained unknown for a long time.
Now, some researchers from Belgium and the U.S. have discovered, and published in the specialized magazine “Science,” how sound production works in the clown fish Amphiprion clarkii. Many strident or creaking sounds are produced by the movement of the jaw and the rubbing of the teeth. Clown fish make these sounds during the search for a partner or while defending their territory.
It was a discovery by Eric Parmentier from the Université de Liège (Belgium) and his collaborators, obtained through a combination of recordings of sounds made by Clark’s Anemonefish (Amphiprion clarkii), video footage and x-rays of the animals.
The sounds are created when the base of the tongue clamps vertically at the same time as the jaw; the teeth clash against each other and send energy to the jaw, which transfers the sounds outside. The closure of the lower jaw is made possible by a structure that was unknown until now and that resembles a bridge.
