That’s a fantastic and funny question! The short answer is no, a fish can’t sneeze like we do. A sneeze is when we forcefully push air out of our nose and mouth to clear out something irritating. Fish don’t have lungs or noses that work in the same way, so they don’t have the ability to do this. However, they have their own special way of clearing out their gills, which are like their lungs.
When something like a piece of food, dirt, or a parasite gets stuck in a fish’s gills, they have a reflex to get rid of it. They do what’s called a “cough” or “gill sneeze.” To do this, they quickly close their mouth and push water forward over their gills with a strong, sudden motion. This rush of water flushes out whatever was bothering them, keeping their gills clean and helping them breathe properly. It’s their clever way of staying healthy underwater.
So, while you won’t ever hear a fish go “achoo!”, their own kind of sneeze is a vital part of their survival. It shows how every animal has amazing adaptations to suit its environment.
