What does it mean when a fish yawns?
by
Fish do not yawn, at least not the way we do. They do open their mouths sometimes, but that is typically to attract mates or deter aggressors. They do not breath in the same way we do, since they do not live in an environment of air. Water passes through gills, allowing the fish to absorb it.
Solution : They gulp water by opening mouth and when they close it, the water moves out from operculum which covers the gill. This they do to breathe, as the dissolved `O_(2)` in water is absorbed by blood capillaries present in gills and `CO_(2)` is given out .
