BLUE WHALE IN ACTION! How the largest creature on the planet lives and hunts!

Mysterious and attractive boundless waters of the oceans.

How many secrets do they keep in their thickness?

After all, not only life arose there long ago, but to this day the largest animal that has ever existed on the planet lives.

You are on the Know TV channel and today we will look at this well-fed marine life, the blue whale.

Don’t forget to rate this video and subscribe to the channel.

Breathe in air.

Deeper we dive: a blue minke, puke or a more familiar blue whale, a real Airship of the underwater world.

We study animals that have remained difficult for many years.

Even scientists specializing in whales had a poor idea of ​​its appearance, and at present, many features of the whale are not fully understood and raise numerous questions.

However, we now know that this incredible mammal, recognized as the largest living on the planet and quite possibly the heaviest in history, because its body length can reach 33 meters and is comparable to a large passenger aircraft, and the mass is capable of going beyond the figure of 150 tons.

Its tongue alone is comparable to the weight of an African elephant, and its circulatory system holds about 8,000 liters of blood.

Although the information that the heart of a whale is comparable in size to a car, and that a child can swim in its aorta, is actually a myth.

There are enough such photos on the Internet, but this is just a model of the heart of a whale, and greatly enlarged.

And here is what the real heart of a 22-meter blue whale looks like.

Of course, it is also huge, but there can be no question of any comparison with a car.

The smooth skin of a forcibly elongated and slender body gives the underwater handsome man excellent streamlining. And even the presence of furrows on the throat and belly does not interfere with this at all.

On the contrary, such skin folds additionally improve the hydrodynamic properties, and also allow the pharynx to be more stretched when swallowing the prey.

After all, if luck presents a feast in such a volume, then here, without hesitation, just open your mouth wider.

Such accumulations of tiny crustaceans are called krill and for the whale this is the main diet.

Given its size, it is not difficult to guess that every day he has to sweat a lot for a hearty lunch, because his daily norm is from 3.5 to 6-8 tons of wings per day.

And this is about 40 million units of individual crustaceans and only for one adult whale, And at a time he swallows over 60 kg of food.

As soon as the krill is in the mouth, its elastic tongue stretches throughout the cavity, literally forming a bag, and water is pushed out by it.

And thanks to the whalebone acting as a colander, the crustaceans remain in place and now they can be swallowed.

The whale mouth, on the other hand, is a dense row of plates, chemically similar to hair.

It grows throughout life and eventually can reach about a meter.

Evaluate these for yourself.

Feels very much like plastic to the touch.

Now for the scale, I found another narrow one, longer than what I showed before.

Well, look at me growth Meter eighty-three.

Also, its lower jaw is so heavy that sometimes it is necessary to turn over during the meal in order to completely close the mouth.

But in general, not everything is so bad.

And the blue whales have adapted quite well to the hungry times, because due to the accumulated fat, the reverend diet is not afraid of them for a whole month of hunger strikes.

Despite their wide distribution – And this is almost the entire World Ocean – it is still quite difficult to meet them, because blue whales prefer to live at a depth of up to 200 meters.

But with luck, he may not be ashamed to show his tail. This is a very rare sight, because due to his weight he is not able to emerge from the water and make such impressive jumps as to collect it.

Periodically, this submarine rises to the surface to breathe a little, releasing air saturated with water vapor from a special body, forming a well-known fountain.

In each species, by the way, the structure of the organ is different.

For example, in toothed whales it is formed by only one nostril, baleen by two, and in sperm whales by two nostrils, one of which is completely overgrown in the course of evolution.

In any case, while watching whales, such a geyser will be hard to miss and I assure you that you will definitely not forget it.

But this inhabitant of the ocean can boast not only in size and weight.

Its voice signals reach 189 decibels at a frequency of 10-15 Hz, which makes it also the loudest on the planet.

This is another of his many mysteries.

Indeed, unlike toothed individuals, the blue whale is devoid of sound lips.

Therefore, sounds are reproduced in the pharynx, but there are no vocal cords in it either.

It makes the loudest sound in the world, but without the presence of special organs for this.

This brings us to a dead end and there is no answer to the question yet, but still you will agree that his singing sounds bewitching And even slightly gloomy.

The unsolved secrets of cetaceans include another interesting, but completely unexplored individual.

It has been nicknamed the 52 Hz Whale, or it is known as the Lonely Whale in the world, probably the only one of its kind that sings at 52 Hz.

It was this feature that served as the basis for the opinion that none of the other whales is able to hear his voice and answer his call.

No one has ever seen this individual, it is not even clear what genus it belongs to, but from time to time scientists record its signals at various points.

The ocean and still the opportunity to explore it is extremely small.

Maybe he’s a hybrid or a mutant, or maybe we’ll never know.

The ocean hides too much and mankind to conquer it.

By nature, blue whales are loners.

They unite in small groups only during hunting or migration, but even in such cases they prefer to keep their distance, because they also have no problems with the exchange of information.

Their built-in radio receiver is capable of receiving signals from other individuals at a distance of as much as 33 km.

However, when it comes to creating a family, whales take this with all seriousness.

These are monogamous animals, therefore, forming a pair of each other, They will never die again.

And in 10-12 months, another record holder will be born, the largest cub on the planet, 9 meters long and weighing up to 3 tons.

By the way, who didn’t know?


The whale is called a calf, because whales are classified as artiodactyls.

Be that as it may, breeding among whales is a very protracted process and, at best, it occurs once every two years.

And the difficulties do not end there, because calves, as the most defenseless, always remain the number one target for predators.

As for the enemies, they are practically absent.

One can only single out the underwater Mafia of killer whales, which at times are not averse to chasing whales or including them in their diet, and the Hunt is not so much for the whales themselves, but for their tongues, lips and throats – the favorite delicacies of black and white bandits.

The whales themselves often remain unfinished, but for the most part, such cases are rarely recorded, and killer whales have enough other objects for hunting.

But man at one time managed to leave a big mark on their population.

The view was practically inaccessible until the second half of the 19th century, but in the 20th century it suffered the main blow.

Floating factories for butchering whale carcasses mercilessly exterminated the giants, which led to a significant reduction in the population.

For example, in 1931 alone, more than 29,000 blue whales were caught.

Whale meat, sparrow and whalebone.

This is what people exterminated whales for, and by the second half of the 20th century, the species had become almost destroyed.

It was then that his trade
