Some species of fish have voices?

That's a great question! While fish don't have vocal cords like humans, many species do communicate using sounds.

Here's how they do it:

* Stridulation: Some fish, like the drum, rub their teeth together or use their bones to create a grating sound.

* Vibrations: Other fish, like the toadfish, contract muscles around their swim bladder, which acts like a drum, to make booming sounds.

* Sounds from the gills: Certain fish, like the croaker, can force air across their gills to create a "croaking" sound.

* Clicks and pops: Some fish use their jaws or teeth to make clicking or popping sounds, especially for echolocation.

So, while fish don't have voices in the traditional sense, they do communicate using a variety of sounds!
