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.

There are several structural differences between bony fish and frogs. Frogs have legs, fish have legs. Fish have gills, frogs have lungs.
A snake has one lung. Humans can also live with only one lung. The one lung compensates for not having two.
A sneeze is a forced expellation of air in response to some irritation in the nose or throat. Fish do not breath air so they can not sneeze.
Rabbits, like all mammals, have lungs, not gills. Lungs are the respiratory organs of mammals, including rabbits, and they are adapted for breathing air. Gills, on the other hand, are the respiratory organs of aquatic animals such as fish and some amphibians. Gills are specialized for extracting oxygen from water, whereas lungs are designed for extracting oxygen from the air. Rabbits breathe by inhaling air through their nostrils, which then passes into their lungs, where oxygen is exchanged with carbon dioxide in the blood.
Fish require gills to breathe underwater. Humans require lungs and a more consecrated form of oxygen. When water gets into the lungs, it will drown the human. Since the torso is human form and the lower portion of the mermaid is in the form of a fish, the most vital element of sustaining the life of such a creature is compromised. Without oxygen, it can not live.....at least, not as it is presented in common depictions.
Mammal is to lungs as fish is to gills.
Do butterflies have lungs?
Fish Use Gills Instead of lungs. Gills Help fish to Breath. Fish Use Gills Instead of lungs. Gills Help fish to Breath.
fish are fish. if they could breathe above water they would be a mammal. no fish have lungs only.
Only whales have lungs .No other fish has lungs they have gills.
Whales breathe with lungs, and fish use gills.
Pneumonia is a disease of the lungs. Fish have gills and do not have lungs. Ergo! Fish can not suffer from pneumonia, so pneumonia can not kill fish.
Whales have lungs, as they are mammals, and fish use gills to breath.
fish!
Fish
wings, lungs
All fish have lungs and gills. The gills extract the air from the water.
