Mostly all fishes have gills to breathe in water because lungs cannot be used to breathe in water. But there are some fishes such as Dolphins,whales,porpoises, etc which have lungs have blowholes on the top of their heads so that as they reach the surface of the water they can forcefully expel air through it.They are known as mammals.
