Detailed explanation-1: -Even though fish can live their lives underwater, they still need oxygen to “breathe”. Instead of breathing air, fish must get their oxygen from the water. This process requires large volumes of water to pass through absorption surfaces to get enough oxygen into their bodies using their mouths and gills.
Detailed explanation-2: -Fishes do not possess respiratory organs like other animals. These can not get enough oxygen on land as they are aquatic animal. These have as a respiratory organ, which they used to filter oxygen from the water present in ponds or oceans.
Detailed explanation-3: -Fish do not breathe air. They get the oxygen they need from the water they live in. Fish have special filters in the sides of their body called ‘gills’ that act as their ‘lungs’.
Detailed explanation-4: -A type of killifish called a mummichog navigates visually, jumping up and orienting its body toward the water, according to a recent study. But West African lungfish blow these other fish out of the water: They have gills and a primitive lung.
