Some submarines dive just over 400 meters, so why can a Ke beaked whale dive nearly 3,000 meters?

Because the inside of the nuclear submarine is empty, the internal pressure is not as strong as the pressure of the water, and the body of the Ke beak whale can produce a lot of pressure, so some submarines can only dive more than 400 meters, and the Ke beak whale can dive nearly 3,000 meters.

This is mainly due to the fact that this species is able to withstand a lot of pressure, and the pressure inside and outside the body is able to reach a balance, so it can dive up to 3000 meters.

Because the Ko's beak whale equalizes the water pressure and makes it easier to control, it can dive up to 3 kilometers.

There are many diving animals on the earth, among which the five deepest diving animals are the Ke's beaked whale, the southern elephant seal, the sperm whale, the beaked whale of the shell, the northern elephant seal, among which they can dive into the deepest depth of the least can be as high as more than 1700 meters, such an excellent record, so that they have a very big reputation.

1. Ko's beaked whale

The Ko's beaked whale is the deepest dive animal in the world, it can dive to 2,300 meters, and the duration of breath-holding under the water can reach minutes, and the record of more than two hours has broken the longest time for a diving animal, and is also known as one of the deepest diving animals in the world. All the structures in the body of the Ko's beak whale are specially prepared for the depths and shallows, its blood has a large amount of blood oxygen, and it has a very high ability to reduce stress, and is called by many people "mammalian deep and shallow water king".

2. Southern elephant seals

Southern elephant seals and northern elephant seals have a lot in common, mainly because they are distributed in different areas, and the southern elephant seals have a larger diving depth than the northern elephant seals, and the southern elephant seals usually dive to a depth of 2388 meters, while the deep diving ability of female seals is usually greater than that of males.

3. Sperm whales

The sperm whale is one of the top 10 intimidating animals, and it has a very big reputation because it is very tall, and both its length and weight are highly regarded. The sperm whale can dive to a maximum depth of 2,250 meters, and the breath-holding time is only ten minutes shorter than that of the Ko's beaked whale, and each breath of the sperm whale can replace 85% of the bond in the body, providing a powerful help for its deep dive.

Fourth, the beaked whale of Belle's

Known by many as the second largest toothed whale after the sperm whale, the Beon's beaked whale stores a lot of oxygen in its body, and its deepest dive can reach a depth of 1,777 meters, while its longest breath-holding time has not yet been determined, but it is speculated to be much longer than the beaked whale in Bryde's.

5. Northern elephant seals

As the sibling of the Southern Elephant Seal, the Northern Elephant Seal has a maximum diving depth of 1,735 meters, its body has a very spleen, and its blood is rich in oxygen, which can support it to dive into the depths of the sea, and its diving ability is enough to surpass most cetaceans.

Whales have nothing to do with submarines, they are two different things.

1. Submarines.

A submarine is a special type of ship (also known as: Blackfish) or submarine, a submarine is a ship that can operate underwater. There are many types of submarines and different shapes, ranging from small civilian submersible probes that are fully automatic or operated by one or two people and operate for several hours, to Russian Typhoon-class nuclear submarines that can carry hundreds of people and dive continuously for 3-6 months.

According to the volume, it can be divided into large (mainly military), medium or small (pocket submarines, submersibles) and underwater automatic mechanical devices.

2. Whales. Whale is a fish belonging to the phylum Chordates, subphylum Vertebrates, Mammalia, and Euzoma, which contains about 98 species of viviparous mammals living in oceans and rivers. There are more than 30 species in China's waters. All but a few species of whales live in freshwater, and all but a few inhabit the ocean.

The definition of the whale itself is vague, and the whale can encompass all cetaceans, as well as specific families of cetaceans. All dolphins are also included in the whales.

There are two main species of whales: baleen whales (mysticeti) and toothed whales (odontoceti). Baleen whales are small but huge, with the smallest known species being over 6 meters long, and the largest animal, the blue whale, is also a baleen whale.

However, the size of toothed cetaceans varies greatly, with the smallest species only about 30 cm in length and the largest sperm whale more than 20 meters long. Whales do not belong to the class of fish, but to the class of mammals.

During the First World War, submarines were created for military necessity to allow ships to sail covertly underwater. When engineers and technicians design a primitive submarine, they first use stones or lead blocks to mount the submarine to make it sink, and if they need to rise to the surface, they throw away the stones or lead blocks they carry to bring the hull back to the surface. Later, after improvement, the method of alternating filling and discharging of floating tanks on the submarine was adopted to change the weight of the submarine.

Later, it was changed to a ballast water tank, with a release valve at the upper part of the water tank and a water filling valve at the bottom, and when the water tank was filled with seawater, the weight of the hull increased so that it could dive into the water. When it is necessary to dive urgently, there is also a speed diving chamber, and after the hull is submerged in the water, the seawater in the speed diving tank is discharged. If one part of the ballast tanks is filled with water and the other part is empty, the submarine can be in a semi-submersible state.

When the submarine wants to float, the compressed air is passed into the water tank and the seawater is discharged, and the submarine can float after the weight of the seawater in the boat is reduced. Such a superior mechanism realizes the free sinking and floating of the submarine. But it was later discovered that the sinking and floating system of fish was much simpler than the invention of people, and the sinking and floating system of fish was just an inflated swim bladder.

The swim bladder is not controlled by muscles, but relies on secreting oxygen into the swim bladder or reabsorbing a part of the oxygen in the swim bladder to regulate the gas content in the swim bladder and promote the free rise and fall of the fish body. However, with such an ingenious sinking and floating system, it was too late for the submarine designers to inspire and help.

The "Whaleback Effect" of Whales and Submarines Contemporary nuclear submarines can dive under the ice for a long time, but if they launch missiles under the ice, they must break the ice and float, which encounters mechanical problems. Inspired by the fact that the whale must break the ice and breathe every 10 minutes, the diving experts have strengthened the material and the shape of the whale's back in terms of the conjugating command platform enclosure and superstructure on the top of the submarine, and indeed achieved the "whale back effect" when breaking the ice.

One heart and one by one, go to the country, and pass a spine of jujubes.
