How a dolphin can surprise you: 8 interesting facts from the life of a good-natured intellectual (8 photos)

Bottlenose dolphins, white-faced dolphins, gray dolphins, Irrawaddy dolphins - the species diversity of dolphins is great! And now there are already those who are on the verge of extinction. But the abilities of our hero only benefit the man. While studying echolocation, we managed to come up with a sonar, echo sounder, and flaw detector! Dolphins bring enormous benefits to humanity. And a person should get to know the mammal better.





Watch out, shark!

It may seem that the call is addressed to dolphins. In fact, this is an appeal to the shark. By studying humpback dolphins, experts were able to assess population losses in Africa. It turned out that 35% of the individuals were attacked by sharks. But dolphins are dolphins because they know how to cooperate.

Seeing that the predator is trying to attack, the dolphins surround her in a flock and begin to poke her in the gill slits one by one. Aim! They know for sure that they can force her to retreat in this way.

Rich fantasy

The human brain weighs on average 1.4 kg, and the dolphin brain weighs 1.7 kg. Researchers at Emory University studied the gray matter of dolphins using MRI and concluded that the structure of the dolphin's auditory sensory pathways allows them to visualize the object they are “hearing.” Just think about it!



The auditory nerve is “connected” to both the areas of the auditory cortex and the primary areas of the visual cortex. Bats have the same ability, which means dolphins are able to read information about any changes in the shape of objects in their path.

Special Tactics

To get enough food, dolphins have to hide. Therefore, a school of dolphins always sends the most experienced ones forward. If the school of provisions is of such a size that the whole group can feed itself with it, then the messenger will appear to the comrades, and the flock will surround the fish. By gradually tightening the ring, the dolphins will force the fish to move in a circle. All the dolphins have to do is open their beaks and eat.





Continuation of the family line

Of all mammals, only dolphin calves pass through the birth canal with their tail first. Giving birth to dolphins is not a quick process. At a minimum, it lasts 20 minutes. And to survive, the average dolphin needs a breath of clean air every 6-7 minutes. We can say that the density of the baby dolphin is even less than the density of water, and it is pulled upward like a magnet. The mother and other females help get to the saving air by pushing the young with their beaks.



Where the quality of water and air is frankly poor, dolphin calves often die. The number of Hector's dolphins has decreased from 30 thousand to 7 thousand, and no more than five thousand dolphins of the Ganges River remain.

Heat generator

The dolphin needs to maintain a normal body temperature of 36.6°. And for this you need to eat often. This is especially true for mothers. Dolphin cubs do not have soft lips and cannot attach themselves to their mother. And it takes a lot of energy to squirt milk straight into your mouth.



Each dolphin requires at least 30 kg of food per day, and the mother works for two. If something happens to the mother, the baby dolphin will not survive. In 2020, a record number of dolphins appeared on the Black Sea coast - 659. The mother, entangled in the nets, cannot take a breath of air and “goes off into the sunset.” What can the boy do?

Main enemy

The deeper the dolphin descends, the more noticeable changes in body density become. Hydrostatic pressure! At a depth of 70 meters, the need to breathe air becomes vital. If the dolphin becomes inactive, it will quickly sink to the bottom.



But even if our hero manages to float to the surface, but cannot place his blowhole above it, he will suffocate. It is for this reason that so many dolphins die in nets.

We remember and love

The researchers also analyzed the emotionality of cetaceans. During the analysis, experts came to the conclusion that dolphins know how to mourn their departed relatives. According to Planet Today magazine, dolphins' emotions are very similar to humans.



Dolphins can create strong and lasting bonds with their fellow tribesmen, and maintain them throughout their lives. Even in the treatises of Aristotle and Herodotus there is information that the emotionality of dolphins has a moral nature.

Third Eye

Dolphins successfully combine vision with X-ray functions. If a person sees just an object in front of him, then a dolphin can visualize its internal structure. Communication by impulses is widespread among dolphins.



But the whistles they make also carry a semantic meaning. Each dolphin has an autograph whistle that allows others to identify it as an individual.

Tatiana Subbotina

“We need to close all dolphinariums. Such highly developed creatures cannot be kept in captivity. Or at least stop going to dolphinariums!”

Do you agree with this opinion?

I agree that the material is not unique (especially on Chips), but rather educational for those who are growing up and curious...maybe someone will be interested...
