Fish gills contain rows upon rows of lamellae, which are thin, disc-like membranes loaded with a capillary network. The water flows across the lamellae, and oxygen and carbon dioxide are exchanged directly across the capillary membrane. Humans have similar capillary interchange sites in the lungs, and the gas exchange occurs in much the same fashion, only the fluid from which we get our oxygen is air, whereas fish get their (dissolved) oxygen from the water.

How do fish take oxygen from water?
yes. fishes receive oxygen under ocean . This is because of aquatic plants.
How do fish suit there environment?
Fish suit their environment because they can breath under water by extracting oxygen through their gills.
How do fish gills separate oxygen from water?
When we go underwater, we have to fill our lungs with air in order to stay under the water. Whales and dolphins also have lungs and also have to resurface in order to spend any length of time under the water. Fish on the other hand don't have lungs and very rarely rise to the top of the water, so just how do they survive? As you probably already know, fish have gills. The water around the fish produces a tiny amount of oxygen. In order for the fish to be able to stay under the water he needs to be able to take in oxygen. The fish's gills do just this. They filter the oxygen in the water and this enables the fish to be able to breathe in water. If you take a fish out of the water, it will die of suffocation. This is because the oxygen in the air has not been filtered through its gills and the fish can't breathe it in properly. When you find your goldfish lying dead on the top of its bowl, it has probably suffocated from a lack of oxygen because they oxygen has been used up by some other means such as bacteria. So always make sure you clean Jaws' bowl out regularly!
How do fish breathe in water?
Most organisms, except for some such as anaerobic bacteria, respire oxygen. Fish have gills, gills have the ability to take the oxygen out of the molecule H2O.Fish have gills, which filter out the oxygen from the water. However, they can't breath out of water.A fish doesn't have lungs, it has gills, so it doesn't breathe in water really.Fish breathe under water by using their GILLSto surviveGills pull oxygen from the water but they can't breathe out of the water because the other chemicals in the air.
Do tadpoles get oxygen from the air or from the water like fish?
Tadpoles get oxygen from water like fish do.
What is another similar characteristic of fish beside breathing?
fish are under water they don't breathe. but they do absorb oxygen from the water through their gills. They're incredibley amazing!
How the function of the gills is performed at shrimp?
