Live Wilderness Adventure

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

Bi Fang grabbed the rock wall and stabilized his body. The two figures had almost disappeared from his perception. Even if they appeared occasionally, they just flashed by.

In ancient Greece, harming dolphins was punishable by death.

The reason for this is that there have never been any stories like dolphins saving people in history.

Mandy is one of the first-hand experiencers. Three years ago, he and many friends surfed on the east coast of Australia. When the second wave was about to hit, a tiger shark hid in it.

It is one of the most ferocious sharks in the ocean. It is the second most ferocious and cruel carnivore in the shark family after the man-eating shark. It is the largest member of the family and genus in which it is currently known.

The maximum body length can reach nearly eight meters!

Eight meters, almost the length of a small van.

They hunt all kinds of marine fish, mammals, seabirds, turtles and even people, and are called "sea tigers".

They are ferocious and gluttonous, with a broad snout like a shovel and teeth like a steak knife.

Because of the tiger-like pattern on his body, he got the name tigershark.

Mandy is definitely not eight meters long, but it is definitely more than five meters, which is much longer than a normal car.

At that time, the pattern of the tiger shark was mixed with the wave pattern reflecting the sunlight, and it shone with a unique light.

It rushed towards Mandy and quickly entered the attack range.

Bi Fang wanted to know what Mandy was thinking at the time, maybe his legs were so soft that he wanted to fall off the surfboard.

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

He lowered his head and thought about it, as if looking at the shark specimens in the glass showcase. Soon, he would also become one of the specimens.

At this moment, a dolphin jumped out, hit the tiger shark from the side, and drove it away.

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

At that moment, at this moment.

The battle between the Niugang trevally and the dolphins was already fixed in Bi Fang's mind.

Dolphins will definitely win.

Just from the data comparison, the Niugang trevally is far from an opponent.

The speed of the Niugang trevally can reach 60 kilometers per hour, but the dolphin can reach the even more terrifying 70 kilometers, close to 20 meters per second, and the limit can reach 80 kilometers, 22 meters per second, fast to the Niugang trevally. Can't touch it at all.

In fact, some scientists once believed that according to the dolphin's own characteristics and shape, its swimming speed cannot exceed 20 kilometers per hour.

If a dolphin swims faster than its muscles can handle, it can only be achieved under two conditions.

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

The second is that it uses some peculiar method to reduce resistance.

This hypothesis was proposed in 1936 by Jan Gray, an aquatic animal research expert in Yanguo, and this theory is called "Gray's Strange Theory".

The muscles of dolphins have no special structure, which was quickly confirmed, and certainly not supernaturally efficient.

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

Is it a form? Someone guessed.

it's not true.

Scientists have made a model of a dolphin, which is exactly the same as a real dolphin from its body shape to its surface. The model is also equipped with a propeller that has the same thrust as the dolphin's tail fin.

The results of the experiment were disappointing, and it was much slower than dolphins.

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

When the upper layer of skin is subjected to water pressure, it will become uneven according to the degree of water pressure.

When the dolphin enters high speed, the turbulence caused by the vibration of the body is adjusted in the uneven changes of the skin, which can greatly reduce the resistance.

Very miraculous.

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

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

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

Small dolphins are fast and agile, and can easily escape 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 over their heads with their strong bodies.

You must know that once a shark is knocked over, it will fall into "tense stillness" and fall asleep.

And in the taxonomy, sharks belong to the subclass of the subclass of the cartilaginous fish class.

Their bones are made of cartilage and connective tissue. Although they are elastic and durable, their density and hardness are far lower than true hard bones.

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

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

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

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

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

To the world of sharks, killer whales are like Chinese table tennis to the international table tennis world. They are beyond **** and even purgatory, and exist like the tip of a pyramid.

What kind of basking shark, weasel shark, porbeagle shark, and sixgill shark, when they encounter killer whales, they are all scared to shit.

Although the Niugang trevally does not have cartilage and connective tissue in its entire body, its abdomen is as soft as it is with sharp spears. Dolphins with high swimming speed are not afraid at all.

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

Bi Fang clenched the harpoon and slowly approached. The closer he got, the clearer his perception became. He could detect the pitted holes on the Niugang trevally, as if it had been repeatedly pierced by a spear.

It seemed that he sensed Bi Fang's approach, and the Niugang trevally wanted to escape, but the spear slammed through the eyeball of the Niugang trevally, hitting the brain directly. The seriously injured Niugang trevally was killed on the spot.

After getting rid of the Niugang trevally, the dolphin seemed very happy and kept swimming in Bi Fang's perception circle.

A bottlenose dolphin.

Previously, the Niugang trevally competed with the dolphin, and the speed was too fast for Bi Fang to sense it carefully, but now he finally saw what kind of dolphin it was.

It is the most common bottlenose dolphins in aquariums, also called needle-billed dolphins and bottlenose dolphins. They are mainly distributed in the temperate and tropical oceans, including the Yellow Sea and Bohai Sea in China.

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

The lifespan of female bottlenose dolphins is about 80 years, while male bottlenose dolphins are not easy to live 50 years due to the more stressful life.

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

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

The bottlenose dolphin in front of him is quite large, over two meters three, and weighs more than three hundred kilograms. With such a large body, it should be a male.

Compared with two meters three, three hundred kilograms, the Niugang trevally, which is only one meter six or seventy kilograms, is nothing at all, just a small fish and shrimp.

No wonder it was solved so easily.

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

As a professional diver, it should be the basic principle not to touch the creatures in your hands at will. Perhaps a little dander from human beings 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 could feel it through the diving suit. The dolphin's skin was smooth as silk and sponge-like, beautiful and textured. Excellent.

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

Another bottlenose dolphin, which is also swimming beside Bi Fang.

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

It is worth mentioning that the nostalgia between members of the bottlenose dolphin group is very strong. If an individual is injured, other members do not escape, but surround the injured companion and cannot bear to give up. It is an extremely compassionate species, and every time One is so.

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

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

Its brain weight is almost the same as that of a human being, at about 1.5 kg.

The human brain has the highest proportion of all animals on earth, at about 2%, while dolphins come in second at about 1.5%.

In addition, the dolphin brain has 18 billion neurons, more than the 13 billion in humans.

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

Dolphins can use ultrasonic waves to sense the skeletal structure of the human body to determine whether the other party is human.

They often rescue drowning humans and lift drowning people to the surface to breathe, just like rescuing their own companions, they will also fight sharks to save humans.

In order to study dolphins, humans have done various experiments, one of which 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 set up a room full of water, and let a female researcher named Margaret live with Peter, 24 hours a day, without separation, eating, sleeping, studying, and having fun together.

This allows Margaret to teach Peter to speak English like a mother teaches a child, and to make him understand and understand human language.

Although dolphins have no vocal cords, they can use the air holes on the top of their heads to make sounds.

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

Amazingly, Peter didn't simply "parrot", because when Margaret said "work, work, work" to him, meaning to call him to learn, he really understood and replied ", ,", told Margaret that he didn't want to study, he wanted to play.

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

However, as the experiment progressed, something unexpected happened.

Peter is more and more reluctant to study, he just wants to be close to Margaret, and he uses various ways to attract Margaret's attention every day.

Peter gets fidgety when Margaret leaves it to go to the toilet.

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

Obviously, it is jealous.

Peter had fallen in love with Margaret, which led the research team to believe that the experiment was going in a direction beyond their control, so the experiment was terminated, and they forcibly separated Peter and Margaret, although Margaret was reluctant to leave Peter, but there's nothing she can do about it either.

When Peter found out that Margaret was no longer there, he became very angry, and he kept swimming in the pool, calling Margaret's name, not eating or drinking.

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

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

But the dolphin's breathing needs the brain rather than the autonomic control, so every breath needs to actively manipulate the muscles.

This is a scientific point of view in the past, and people use it to explain the reason why dolphins kill themselves by holding their breath, and it is widely circulated.

But Richard told Bi Fang that this was inaccurate.

Some people have used complex and complete anesthesia experiments to prove that dolphin breathing can be either "automatic" or actively controlled.

They can suffocate and commit suicide by closing their stomata.

So everything is proven.

This dolphin died in love.

What is suicide?

This is a complex issue. Modern science is so inaccurate, but it still does not fully understand why humans commit suicide, and the risk factors for human suicide are still undetermined.

The Ugly Nation Psychiatric Association lists suicidal behavior as a "disorder for further consideration~www.readwn.com~ Even what constitutes a determinant of human suicide is controversial - a matter of biology and psychology as well as philosophy and semantics. The problem.

It has also been pointed out that even among humans, prepubertal children, or children with developmental disabilities, suicidal behavior is rare.

Human children cannot understand the concept of suicide, and the most intelligent non-human animals are unlikely to surpass human adolescents at the level of intelligence, and it seems even less likely to expect them to understand their own death and have the ability to perform suicidal acts.

In Bi Fang's view, the so-called suicide requires that the actor must 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 data and archives were sealed at the time and have not been made public.

It wasn't until 2014 that the experiment was finally declassified.

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

He punched the dolphin **** the head.

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