Live Wilderness Adventure

Chapter 546 I want to beat you

Thirty meters under the sea, a fierce fight is going on.

Bi Fang grabbed the rock wall and stabilized his figure. The two figures had almost disappeared from his perception range, and even if they appeared occasionally, they just passed by in a flash.

In ancient Greece, harming a dolphin was punishable by death.

The reason for this is that there has never been a shortage of stories like dolphins saving lives in history.

Mandy is one of those who experienced it personally. Three years ago, he and many friends were surfing on the east coast of Australia. When the second big wave was about to hit, a tiger shark hid in it.

It is one of the most ferocious sharks in the ocean. It is a ferocious and cruel carnivore second only to man-eating sharks in the shark family. It is the largest member of its family and genus known so far.

The maximum body length can reach nearly eight meters!

Eight meters, almost the length of a small van truck.

They hunt and kill all kinds of marine fish, mammals, seabirds, turtles and even humans, and are known as "tigers in the sea".

They are ferocious and voracious, with broad, spade-like snouts and steak-knife-like teeth.

Because of the tiger-like pattern on its body, it has the name tiger shark.

Mandy must not have met eight meters, but it was definitely more than five meters, which was much longer than normal cars.

At that time, the pattern of the tiger shark was mixed with the wavy pattern reflecting the sun, shining a unique light.

It rushed towards Mandy and quickly entered the attack range.

Bi Fang really wanted to know what Mandy was thinking at that time, maybe her legs were so weak that she was about to fall off the surfboard.

The distance between the two sides was less than two meters. Mandy's fingers slid across the waves. Under the refraction of the sun, it was like touching the skin of a shark.

He looked down, as if looking at a stuffed shark in a glass display case, and soon, he would be one of the stuffed ones.

At that moment, a dolphin jumped out and flanked the tiger shark, driving it away.

At that moment, Mandy felt the strongest sense of connection with animals in his life, so much so that even today, three years later, he still enjoys telling this story to everyone.

At that moment, at this very moment.

The battle between Niugang trevally and dolphins has long been a decision in Bi Fang's mind.

The Dolphins are bound to win.

Only from the comparison of data, Niugang trevally is far from rival.

Niugang trevally can reach a speed of 60 kilometers per hour, but dolphins can reach an even more terrifying 70 kilometers, close to 20 meters per second, and the limit can reach 80 kilometers, 22 meters per second, as fast as Niugang trevally Can't touch its shadow at all.

In fact, some scientists once believed that according to the characteristics and shape of a dolphin, its swimming speed should not exceed 20 kilometers per hour.

If a dolphin swims faster than its muscles can bear, it can only be achieved in the following two cases.

One is that the muscles of dolphins are supernaturally efficient, 6 times stronger than that of ordinary mammals.

The second is that it uses some fancy method to reduce drag.

This hypothesis was put forward by Jan Gray, an expert on aquatic animals in Yangzhou in 1936. This theory is called "Grey's strange theory".

The muscles of dolphins have no special structure, it was soon established, and certainly not supernaturally efficient.

Therefore, according to existing speculation, it must be the second reason that leads to the high-speed swimming of dolphins.

Is it a form? It's anyone's guess.

it's not true.

Scientists made a model of a dolphin, which is exactly the same as a real dolphin in terms of size and appearance, and a propeller that is the same as the thrust produced by the dolphin's tail fin is installed on the model.

The results of the experiment were disappointing. It was much slower than the speed of dolphins.

After further research by many physical biologists, it was discovered that the skin of dolphins is divided into upper and lower layers. The upper layer is the outer layer, which is very elastic; the lower layer, the inner layer, is also very elastic.

When the upper layer of skin is subjected to water pressure, it becomes bumpy depending on the level of water pressure.

When the dolphin enters high-speed operation, the turbulence caused by the body vibration will be adjusted in the unevenness of the skin, so that the resistance can be greatly reduced.

Extremely amazing.

In addition, dolphins look cute, but they firmly occupy the top of the marine food chain, and their fighting power is stronger than most people think.

Sharks are the most ferocious fish in the ocean. Known as "wolves in the sea", they live on injured marine mammals, fish and carrion. They cull the weaker members of animals. They have few opponents in the ocean, but ferocious sharks Rarely attack dolphins.

Fish are afraid of sharks, and sharks are afraid of dolphins.

Small dolphins are fast and flexible, and can easily avoid shark attacks. It is very difficult for a shark to bite a dolphin, but it is very easy for a dolphin to attack a shark.

Although large dolphins are not so flexible, they can knock sharks off their backs with their strong bodies.

It is important to know that once a shark is knocked over, it will fall into "tonic immobility" and fall asleep.

And in biological taxonomy, sharks belong to the species of elasmobranchs under the class of cartilaginous fishes.

Their bones are composed of cartilage and connective tissue. Although they are elastic and durable, their density and hardness are far lower than that of real hard bone.

In addition, sharks have no ribs, so the lower side of the body and the abdomen are the weakest parts of their body defense.

Dolphins are aquatic mammals, with hard upper and lower jaw bones, and a protruding snout like a sharp spear.

When the two are really fighting for life and death, the dolphin will not let go of the shark's weakness.

It's like piercing wet window paper with your fingers - as long as the speed and strength are appropriate, the spear-like snout of a dolphin can even directly pierce the shark's body, causing fatal damage to the shark.

Moreover, in the dolphin family, there is also a "King" in the shark world-killer whales.

Killer whales are to the shark world, just like Chinese table tennis is to the international table tennis world. It is beyond hell, even purgatory-level difficulty, and exists like the top of the pyramid.

What basking sharks, tiger sharks, porbeam sharks, sixgill sharks, when they meet killer whales, they are all scared to death.

Although Niugang trevally does not have cartilage and connective tissue all over its body, its abdomen is as soft and has sharp spears. Dolphins with super high swimming speeds are not afraid at all.

In Bi Fang's perception circle, when Niugang trevally appeared again, its speed had dropped a lot, and it was quietly floating in the water.

Bi Fang grasped the harpoon tightly and approached it slowly. The closer he got, the clearer his perception became. He could feel the bumpy holes in Niugang trevally's body, as if repeatedly pierced by a spear.

Seemingly sensing Bi Fang's approach, Niugang trevally wanted to escape, but a spear pierced through Niugang trevally's eyeballs and hit the brain directly, killing the seriously injured Niugang trevally on the spot.

The dolphin seemed very happy after the Niugang trevally was disposed of, and kept swimming in Bi Fang's perception circle.

It's a bottlenose dolphin.

Previously Niugang trevally fought with dolphins, the speed was too fast, Bi Fang had no time to sense carefully, now he finally figured out what kind of dolphin it was.

It is the most common bottlenose dolphin in the aquarium, also called sharp-billed dolphin and bottle-nose dolphin. It is mainly distributed in temperate and tropical oceans, including the Yellow Sea and Bohai Sea in China.

The kiss is long, the mouth is short, and the shape of the mouth seems to be always smiling. It is a second-class protected animal in China.

The life span of female bottlenose dolphins is about 80 years, while male bottlenose dolphins are not easy to live beyond 50 years due to greater life pressure.

This dolphin has a very high intelligence, self-awareness, strong feelings, and even strategy.

Some people believe that the intelligence of dolphins should be ranked in front of chimpanzees, second only to humans.

The bottlenose dolphin in front of me is quite large, over 2.3 meters in size, and definitely weighs more than 300 kilograms. With such a large size, it should be a male.

Two meters three, three hundred kilograms, compared with it, only one meter six, about seventy kilograms, is nothing at all, just a small fish and shrimp.

No wonder it was resolved so easily.

Seeing the dolphins swimming beside him, Bi Fang couldn't help reaching out to touch them.

As a professional diver, it should be the basic rule not to touch the creatures in your hands casually. Perhaps a little human dander will cause damage to the underwater ecological environment.

Bi Fang's fingers touched the swimming dolphin. The bottlenose dolphin looked very calm. Bi Fang pressed hard, and he could feel it through the diving suit. The dolphin's skin was as smooth as silk and textured as a sponge. It was beautiful and textured. Excellent.

After waiting quietly for a while, another streamlined creature broke into Bi Fang's perception circle.

Another bottlenose dolphin was swimming beside Bi Fang.

Male bottlenose dolphins usually live alone or in small groups of 2 or 3, and they only join large groups of other female bottlenose dolphins for short periods of time.

It is worth mentioning that the members of bottlenose dolphins are very attached to each other. If an individual is injured, other members will not escape, but will surround the injured companion and cannot bear to abandon it. They are extremely compassionate species, and every time All of them are like this.

From this point of view, dolphins are much smarter than humans.

On this planet, dolphins are second only to humans in intelligence.

Its brain weighs almost the same as that of a human, at about 1.5 kilograms.

Humans have the highest proportion of brain among all animals on earth, about 2%, while dolphins rank second, about 1.5%.

In addition, the dolphin brain has 18 billion neurons, which is more than the 13 billion of humans.

Therefore, dolphins are far superior to other animals in terms of comprehensive brain data indicators, and they are second only to humans.

Dolphins can use ultrasonic waves to perceive the bone structure of the human body, so as to judge whether the other party is human.

They often rescue humans who fall into the water, and lift the drowning people to the surface of the water to breathe, just like saving their companions, they will also fight sharks to save humans.

In order to study dolphins, humans have done various experiments, among which a secret experiment was not revealed until more than 50 years later.

In 1963, funded by NASA, an experiment was conducted on a male bottlenose dolphin named Peter in the U.S. Virgin Islands. The purpose of the experiment was to study whether dolphins could learn human language and successfully communicate with humans.

The experimental team arranged a room filled with water, allowing a female researcher named Margaret to live with Peter 24 hours a day, eating, sleeping, studying and entertaining together.

In this way, Margaret taught Peter to speak English like a mother teaches a child, and let him understand and understand human language.

Although dolphins do not have vocal cords, they can use the blowhole on the top of their head to produce sound.

The dolphin Peter showed amazing learning ability. In less than two weeks, he learned to say the numbers "one, two, three" and simple greetings like "hi, hello", and finally learned more than 700 words in English word.

What is incredible is that Peter did not simply "parrot", because when Margaret said "work, work, work" to him, which meant to tell him to study, he could really understand and replied "play , play, play", telling Margaret that it doesn't want to study, it wants to play.

Even when Peter wants to eat fish, he will say "Fish in bucket" to Margaret, which means that he wants to eat the fish in the bucket.

However, as the experiment progressed, something unexpected happened.

Peter became more and more unwilling to study, and only wanted to get close to Margaret. He used various methods to attract Margaret's attention every day.

When Margaret leaves it because she's going to the bathroom, Peter becomes restless.

When Margaret was on the phone, Peter would yell at the phone.

Obviously, it was jealous.

Peter has fallen in love with Margaret, which made the research team think that the experiment was developing in a direction beyond their control, so the experiment was terminated, and they separated Peter and Margaret forcibly, although Margaret was unwilling to leave Peter, but there was nothing she could do about it.

When Peter found out that Margaret didn't show up again, he became extremely angry. He kept swimming around in the pool, calling Margaret's name, and didn't eat or drink.

One day a few weeks later, Peter dived under the pool, refusing to come up to the surface to breathe, and he suffocated himself.

The breathing method of dolphins is completely different from that of other animals. It is absolutely impossible for human beings to commit suicide by holding their breath, because after suffocation and coma, the body will instinctively let go of breathing.

But dolphin breathing requires brain rather than autonomic control, so each breath requires active manipulation of muscles.

This is a scientific point of view in the past. People use it to explain the reason why dolphins hold their breath and commit suicide, and it is widely circulated.

But Richard told Bi Fang that this was not accurate.

Someone has used complex and complete anesthesia experiments to prove that the breathing of dolphins can be "automatic" or actively controlled.

They can kill themselves by suffocating by closing their pores.

So everything is proven.

This dolphin died in love.

What is suicide?

This is a complex issue. Modern science is so advanced, but it still doesn't fully understand why humans commit suicide, and the risk factors for human suicide are still undetermined.

The American Psychiatric Association lists suicidal behavior as a "disorder that requires further consideration."

Even the determinants of what constitutes human suicide are debated—a matter of biology and psychology, as well as philosophy and semantics.

It has been further pointed out that even among humans, prepubescent children, or children with developmental disabilities, rarely commit suicide.

No human child can understand the concept of suicide, nor is it possible for the smartest non-human animal to surpass the intellectual level of a human adolescent, and it seems even less likely that they will be able to understand their own death and possess the ability to perform suicide.

In Bi Fang's view, the so-called suicide requires the actor to have self-awareness, understand the true meaning of death, and be able to perform a series of behaviors that he knows will lead to his own death.

Everything proves that dolphins have a very high self-awareness.

Because this experiment involved ethical and moral issues, the materials and files were sealed up at the time and have not been made public.

It was not until 2014 that the experiment was finally declassified.

Bi Fang spit out a bubble slowly. He looked at the dolphin beside him and slowly clenched his fist, all the muscles in his body were mobilized.

He punched the dolphin hard on the head.

You helped me, but I'm sorry to hurt you.
