Can fish cough?

Well, can they?

Is there any type of fish that can cough?

What about sneeze?

Almost all fish are noted for their talents at “spitting out” undesirable items (e.g. fish hooks), a behavior Wainwright says is more accurately described as “coughing.” Snail- and other mollusc-munching species are experts at ejecting showers of shell fragments, for example.

Tetradonts are superb “coughers,” says Wainwright, but where some of them really shine is in their abilities to blow water, a specialty which he believes may be unique to the group whose members all have rather small, flute-like mouths eminently suited to the task. Triggerfish, for example, can fire jets of water powerful enough to overturn large sand dollars and even small rocks, he said.

As the fish swim, breath and cough, yes, fish cough, their movements are detected by non-contact sensors mounted in the IAC 1090 aquarium," company officials said in a statement. “Should the fish detect toxic conditions, an alarm is triggered and the IAC 1090 is prompted to immediately take a series of water samples.”

I bet they do when they bite down on that hook.

If they can’t cough it out.
