Oxygen is a natural element which no animal can live without. Many people are surprised to learn that fish and other aquatic organisms don't use oxygen from water molecules (H2O). ... This is because the single oxygen molecule (O) is bound to the two hydrogen molecules (H2) and is not useable in this form.

How do underwater animals get oxygen from the water?
Humans use their lungs to inhale oxygen from the air. But worms, fish, crabs and other underwater animals use gills to get oxygen from the water. As water moves across an animal's gills, oxygen is removed and passed into the blood. Gills work better when there is more oxygen in the surrounding water.
Do marine animals use oxygen?
Like animals on land, marine animals use oxygen to breathe, and both plants and animals use oxygen for cellular respiration.
How do marine animals breathe underwater?
Home > About whales & dolphins > How do whales and dolphins breathe? Whales and dolphins are mammals and breathe air into their lungs, just like we do. They cannot breathe underwater like fish can as they do not have gills. They breathe through nostrils, called a blowhole, located right on top of their heads.
Do all aquatic animals breathe oxygen dissolved in water?
No, not all aquatic mammals breathe oxygen dissolved in the water. Some aquatic animals such as dolphins come to the surface of the water to breathe the oxygen present in the air. Only those aquatic animals breathe through the oxygen dissolved in water which have gills modified for gaseous exchange.
Which sea animal Cannot breathe in water?
Whales cannot breathe underwater because they are mammals and not fish. This means that their breathing organs are lungs, rather than gills.
Why does dissolved oxygen decrease in water?
Low dissolved oxygen (DO) primarily results from excessive algae growth caused by phosphorus. Nitrogen is another nutrient that can contribute to algae growth. As the algae die and decompose, the process consumes dissolved oxygen. ... Die-off and decomposition of submerged plants also contributes to low dissolved oxygen.
How do coral reefs produce oxygen?
Most corals, like other cnidarians, contain a symbiotic algae called zooxanthellae, within their gastrodermal cells. ... In return, the algae produce oxygen and help the coral to remove wastes. Most importantly, they supply the coral with organic products of photosynthesis.
How do deep sea fish get oxygen?
In order to remove oxygen from the water, they rely on special organs called "gills." ... A fish breathes by taking water into its mouth and forcing it out through the gill passages. As water passes over the thin walls of the gills, dissolved oxygen moves into the blood and travels to the fish's cells.
How do vertebrates breathe?
ALL VERTEBRATES (animals with a spinal cord, including humans) on land breathe with LUNGS. When you take a breath, a muscle below the rib cage called the DIAPHRAGM presses downward to allow air to fill the lungs, two hollow organs on either side of the heart.
Where do sea water fishes get their supply of oxygen?
As the fish opens its mouth, water runs over the gills, and blood in the capillaries picks up oxygen that's dissolved in the water. Then the blood moves through the fish's body to deliver the oxygen, just like in humans.
What animals absorb dissolved oxygen?
Dissolved Oxygen and Aquatic Life
Fish and crustaceans obtain oxygen for respiration through their gills, while plant life and phytoplankton require dissolved oxygen for respiration when there is no light for photosynthesis 4.
What are the special adaptation of animals to breathe dissolved oxygen?
Aquatic animals may breathe air or obtain oxygen that is dissolved in water through special organs called gills, or directly through the skin. and move around on land but only for short periods. In addition to gills for them to breathe underwater, they also have gill chambers.
Why mammals Cannot breathe underwater?
The oxygen is useless to our lungs in this form. The oxygen that fish breathe is not the oxygen in H2O. ... Humans cannot breathe underwater because our lungs do not have enough surface area to absorb enough oxygen from water, and the lining in our lungs is adapted to handle air rather than water.
Can a fish survive in milk?
The simple answer is "no," but the nuanced response sheds light on how fish, and all other organisms, function. Fish have evolved over many millions of years to survive in water with a certain amount of dissolved oxygen, acidity, and other trace molecules.
