Fish make a surprising variety of noises using methods like vibrating their swim bladder or rubbing bones together.

Sounds range from grunts and hums to chirps and clicks, creating underwater choruses for reproduction or territorial displays.

They do this to primarily to attract mates, defend territory, find food, and warn of predators, as sound travels well underwater.

Over 800 species are known to produce sounds, making the ocean a much noisier place than commonly thought.

Many bony fish vibrate muscles attached to their swim bladder (a gas-filled sac) like a drum.

Some fish, like herring, expel air from their swim bladder through their anus, creating rapid chirps (FRT).

Some have unique mechanisms, like the Danionella fish which uses a drumming cartilage against its swim bladder.
