Fishy Fact
Here's a wild fun fact for you: Fish can cough. But it doesn't make a sound when it does. A fish uses its gills to extract a small amount of oxygen they find in the water and then releases it in gases (just like carbon dioxide). During this process, it is possible for particles or bacteria to get sucked in through the gills. So, when these particles go into a fish’s gills, their ventilation cycle is interrupted by a cough.
