The answer is that oxygen is stored in the blood and muscles, not in the lungs. Marine mammals have a very high volume ratio of blood to body. Increased levels of respiratory pigment in blood and muscle are important indications in diving mammals. Blood oxygen stores in diving mammals vary from near-normal to more than three times normal in terrestrial mammals, while muscle oxygen stores range from near-normal to nearly ten times normal. To survive in the ocean, whales needed to adapt their lungs to make them easier to breathe. Hold your breath for a long time when submerged in water. Whales are not born with very large lungs, but can exchange 90% of the oxygen they inhale compared to humans who exchange only 10% to 15%. The most prominent adaptation of cetaceans to life in the water is the locomotive system. Setasean is a descendant of mammals that move their limbs in a vertical plane rather than a horizontal plane, so when swimming, use vertical strokes rather than horizontal strokes like crocodiles and fish.

What adaptations do mammals have for diving?
Increased levels of respiratory pigment in blood and muscle are important indications in diving mammals. Blood oxygen stores in diving mammals vary from nearly normal to more than three times normal in terrestrial mammals, while muscle oxygen stores vary from near normal to nearly ten times normal.
What adaptations do whales need to survive in the ocean?
Adaptation of marine mammals. The sperm whale seen in the figure above is a marine mammal diving champion. Sperm whales can stay in the water for more than 90 minutes and dive to a depth of about 10,000 feet. Sperm whales have various adaptations to allow them to dive very deeply.
What are the physiological indications for cetaceans?
The following points highlight the nine major physiological adaptations of cetaceans. The physiological indications are: 1. Thermoregulation 2. Eating habits 3. Osmoregulation 4. Lung ventilation and deep sea diving 5. Slow veins 6. Miraculous retina 7. Reproduction 8.
Why study the anatomy of aquatic mammals Is it?
These studies highlight the dramatic anatomical changes seen in the evolution of fossil ancestors to extant aquatic mammals. This special issue is a tribute to the unique anatomical morphology and function of aquatic mammals that allows them to adapt to life in the water.
What are the physiological adaptations of diving animals?
Some anatomical and physiological characteristics (weight gain, relative lung size reduction, blood volume increase, myoglobin concentration increase, etc.) are also found in deeper diving species. It suggests that it is a diving-related indication (electronic supplement, Table S1).
Which of the following is the adaptation of marine mammals to deep-sea diving?
One of the adaptations to deep diving is an increase in heart rate during the dive. Many cetaceans can extract 90% of oxygen from each breath.
What are the physiological adaptations that allow seals to dive deep and long?
Two adaptations help seals extend their time in the water. Than terrestrial mammals with large oxygen storage capacity. They have a high blood volume per body weight and a high number of red blood cells per blood volume. Muscle myoglobin is up to 20 times more concentrated than terrestrial mammals.
Why do marine mammals dive so deeply?
Diving mammals lower the heart rate, stop blood flow to specific parts of the body, and temporarily block organs such as the kidneys and liver while hunting. Dr. Hooker said:
