Question

In an aquarium, you can find different types of rare fishes with proper aeration.
You can see that on both sides of the head of a fish, there is a flap-like structure
called operculum that cover the gills. You can see these flaps open and close
alternatively. Try to give an explanation about this movement of flaps. Also,
