Aquatic animals may breathe air or extract oxygen from water through specialised organs called gills, or directly through the skin. Natural environments and the animals that live in them can be categorized as aquatic (water) or terrestrial (land).

How do aquatic animals get oxygen?
The process of breathing in aquatic animals starts from the intake of water inside the mouth and forcing it out through the gill passages. The dissolved oxygen gets filtered by the thin walls of gills as the water passes through the gills.
How are aquatic animals are able to survive?
Aquatic plants and animals are able to survive in water as water contains 0.7% of dissolved oxygen which is taken inside their body by specially designed organs like gills and by general body surface in plants.
How do fish get their oxygen?
Fish take water into their mouth, passing the gills just behind its head on each side. Dissolved oxygen is absorbed from—and carbon dioxide released to—the water, which is then dispelled. The gills are fairly large, with thousands of small blood vessels, which maximizes the amount of oxygen extracted.
Why do aquatic animals need oxygen?
Aquatic organisms absorb molecular oxygen from water and use it to oxidize organic compounds and release energy for doing biological work. In the process called respiration, they also must expel carbon dioxide, the resulting waste.
How do fish and aquatic animals survive in water?
But the water beneath this thick layer of the ice does not freeze into a solid but remains as a liquid. ... This expansion enables marine life (fishes or marine plants) which exist in the colder regions to survive, even when the water solidifies on the surface and below the surface is still liquid.
How do aquatic plants help aquatic animals in breathing?
Dissolved-oxygen gas is released as a by-product. In aquatic environments, free-floating microscopic plants known as algae, and larger submersed plants (macrophytes), release oxygen directly into the water where it is used by animals and other organisms, including the plants themselves.
How do aquatic plant survive in water?
Aquatic plants require special adaptations for living submerged in water, or at the water's surface. The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floating leaves and finely dissected leaves are also common.
How do animals breathe?
ALL VERTEBRATES (animals with a spinal cord, including humans) on land breathe with LUNGS. ... They breathe with GILLS, flaps of skin on both sides of their heads or in their mouths. When water flows into their mouths and out through their gills, their red blood cells absorb the oxygen.
How does a mammal breathe?
Most mammals breathe through their mouths and noses and send oxygen to their body via the lungs. A few aquatic animals, including sea cucumbers and catfish, breathe through their intestines, and the intestinal tissues of humans can readily absorb pharmaceuticals.
How do frog breathe?
Frog Respiration. The frog has three respiratory surfaces on its body that it uses to exchange gas with the surroundings: the skin, in the lungs and on the lining of the mouth. While completely submerged all of the frog's repiration takes place through the skin.
How do fish get oxygen in water?
The best way to increase oxygen is to increase the surface area of the aquarium. Increase Surface agitation or water movement on the surface. This allows more oxygen to dissolve and more carbon dioxide to escape. You can also add a source of fresh oxygen by installing an air pump.
How do fishes and aquatic animals survive in the winter when the pond gets covered with thick ice?
Due to the anomalous expansion, only the upper surface to water gets frozen into ice. As density of ice is less than that of water, ice floats on water. The deeper layers of the pond help aquatic life to survive as the temperature remains a bit higher than the temperature of the upper layers. Hope it helps u.
How do fish get oxygen in a frozen lake?
Different fish species do this either by absorbing oxygen into their skin, into the blood vessels in the walls of their swim bladders, stomach and gut, and some even inhale the air bubbles that form underneath the ice through their mouth.
Why aquatic animals survive in frozen seas?
When water boils at a certain temperature it turns into steam. When it is cooled to a certain temperature it freezes and becomes ice. ... Also, oxygen is trapped beneath the layer of ice. As a result, fish and other aquatic animals find it possible to live comfortably in the frozen lakes and ponds.
How do aquatic animals survive in water class 6?
The streamlined shape of sea animals is an adaptation for swimming in water. (2) Most of the sea-animals have gills which enable them to use oxygen dissolved in water for breathing. So, the presence of gills in sea-animals is an adaptation for breathing inside the water.
