Whales breathe differently in the sea than humans. They do not breathe through their noses, but through the fumaroles above their heads. This fumarole quickly expells excess carbon dioxide from the whale's body while inhaling fresh oxygen.
When there is a typhoon, the fluctuations in the sea may affect the whales' breathing, but usually do not cause much of a problem for them. Whales use their keen hearing and sensory organs to detect their surroundings and adjust the rhythm and depth of their breathing accordingly to ensure that they are able to breathe properly. In addition, many cetaceans have the ability to dive and can stay underwater for a period of time without breathing, which can also help them avoid breathing problems during typhoons.
In conclusion, whales can cope with the fluctuations of the sea by adjusting their breathing rhythm and diving ability when there is a typhoon in the sea.

As the saying goes, "the sea is rough, but the bottom of the sea is calm as usual", and typhoons are unlikely to affect the biological world at the bottom of the sea. Generally, deep-sea fish are not affected, and there is a large amount of oxygen ...... in the sea

Whales are a class of mammals. Although there are some differences from terrestrial mammals, they breathe in the same way, using their lungs to breathe. The lungs are an important site for gas exchange.
When you breathe, the exhaust gases from the lungs are expelled and fresh air is inhaled. Nostrils also play an important role in this process. During specific breathing, the nostrils expel a mixture of gas and water and send fresh air into the lungs.
Breathing plays a very important role in the life activities of animals, and different animals have different ways of breathing. To understand how whales breathe, one should first make it clear that they are mammals. They are an aquatic mammal due to living in water.
Although it differs from terrestrial mammals in some characteristics, it is the same in terms of breathing patterns. Whales use their lungs to breathe. It is different from the way fish use gills to breathe.
In addition to the lungs, the nostrils also play an important role in their specific breathing.
When it comes to breathing, whales will pick a suitable time to breathe and then poke their heads out of the water, and they will expel the air from their lungs, which will be sprayed out of their nostrils along with the surrounding seawater. The whales then suck a lot of air into their lungs, which can be used for long dives.
The organs used by whales to breathe and the methods used by them have already been mentioned above. It can be seen that whales must be out of the water when they breathe, and they cannot breathe at the bottom of the sea. Therefore, this characteristic makes it impossible for whales to be on the bottom of the sea all the time, but need to breathe in the water every once in a while, and it is not possible to stay on the bottom of the sea for a long time.
However, unlike humans and other animals, whales can choose when they want to breathe, while humans and most other animals are basically passive and have to breathe non-stop. After a single breath, different whales can hold on for different times, with some whales holding on for up to several hours.

Whales and dolphins are completely aquatic mammals, they also have ears, but their ears do not have the outer pinna, the middle and inner ears are fully developed, and the outer ear is just a small hole and is completely closed on the way to the middle ear, which prevents the water from entering. Whales and dolphins do not rely on the outer ear to hear sounds, and whales have a layer of fat in the jaw, so sounds from the sea can reach the middle ear directly through these fat layers. The external auditory canal doesn't actually work.
Sea lions, seals and other semi-aquatic mammals are actually semi-aquatic mammals, and they also have to go ashore to give birth. The pinna of the sea lion is still present, but it has degenerated so little that it is barely visible. The pinna of the seal has completely degenerated.
But they all have an external auditory canal and an intact internal structure that allows them to hear sounds. However, they have all evolved the ability to close the external auditory canal in water, and water cannot enter.
As for their noses, I don't know if you've observed them, but once their heads are immersed in water, their nostrils close completely. This is true for whales, dolphins, sea lions, seals, walruses, and fur seals.

Forget about the ears, if you go into the water, nothing will happen if the ears get into the water (unless there is a wound in the ear).
The nose is ......This problem simply does not exist. Because whales, dolphins, and sea lions choke on their noses like they enter the water!
Nothing moreAquatic mammals can have longer breath-holding periodsThat's it.
When humans fall into the sea, dolphins instinctively react to rescue humans, because dolphins like to play in the water, and they prefer to imitate and move, and I think he is still very kind, so he will go to rescue humans
We all know that fish can breathe freely in the water, not because they have nostrilsIt's because they have a body part that we humans and other animals don't have, and that's the gills that allow fish to breathe freely in the waterOn the other hand, there are fish that can breathe in the water and they can breathe on land, and that is the African lungfish, so the fish can breathe in the water precisely because they have gills. <> >>>More
All clothes and sundries are sorted, packaged, and bagged (moisture-proof), away from balconies and windows (after tidying up, the home is basically smooth except for furniture and household appliances).
Sing with your dantian. Try putting your hand on your abdomen while singing. Then when you sing, feel that all the sounds are running over your head. This is the essence of singing, as for the problem of ventilation, do more monosyllabic vocal exercises.
About a century ago, in Anyang, Henan Province, China, there was a major archaeological discovery, which was the discovery of Yin Ruins and oracle bone inscriptions. Since then, the study of the history of the Yin Shang dynasty in China has entered a new period. According to Chinese paleographers, the oracle bone inscription is "the earliest and relatively complete script that can be seen so far". >>>More
