Chapter 543 I'm Going to Beat You
Thirty meters below the sea, a fierce battle is going on.
Bifang grabbed the rock wall and steadied his body. The two figures had almost disappeared from his perception range. Even if they appeared occasionally, they were only a flash.
In ancient Greece, harming a dolphin was punishable by death.
The reason for this is that there has always been a lot of stories in history about dolphins saving people.
Mandy is one of those who have experienced this. Three years ago, he and many friends were surfing on the east coast of Australia. When the second wave of big waves was about to hit, a tiger shark was hiding among them.
It is one of the most ferocious sharks in the ocean. It is the most ferocious and cruel predator in the shark family after the man-eating shark. It is the largest member of its family known to date.
The maximum body length can reach nearly eight meters!
Eight meters, almost the length of a small van truck.
They prey on all kinds of marine fish, mammals, seabirds, turtles and even humans, and are known as "tigers of the sea."
They are ferocious and voracious eaters with broad, shovel-like snouts and a mouthful of steak-knife-like teeth .
It is named tiger shark because it has tiger-like patterns on its body.
The car Mandy encountered was definitely not eight meters long, but it was definitely more than five meters long, much longer than a normal car.
At that time, the tiger shark's patterns were mixed with the wave patterns reflecting the sunlight, shining with a unique light.
It rushed towards Mandy and soon came within attack range.
Bifang 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 two sides were less than two meters apart. Mandy's fingers brushed across the waves, and under the refraction of the sunlight, it was like touching the shark's skin.
He lowered his head and looked down, as if he was looking at a shark specimen . Soon, he would become one of the specimens.
Just then, a dolphin jumped out and knocked the tiger shark away from the side, driving it away.
At that moment, Mandy felt the strongest connection with animals she had ever felt in her life, so much so that she still remembers it today, three years later, and she still enjoys telling this story to everyone.
At that time and moment, it was just like this moment.
Bifang had already decided the battle between the Niugang trevally and the dolphin.
The Dolphins will definitely win.
Judging from the data alone, Niugang trevally is far from being a match.
The speed of the Niugang trevally can reach 60 kilometers per hour, but the dolphin can reach an even more terrifying 70 kilometers per hour, close to 20 meters per second. The limit can reach 80 kilometers per hour, 22 meters per second, so fast that the Niugang trevally can't even touch its shadow.
In fact, some scientists once believed that based on the dolphin's own characteristics and body shape, its swimming speed could not exceed 20 kilometers per hour.
If a dolphin swims faster than its muscles can handle, it is only possible under two circumstances.
First, dolphins' muscles are supernaturally efficient, six times stronger than those of ordinary mammals.
Second, it uses some strange method to reduce resistance.
This hypothesis was proposed by James Gray, an expert on aquatic animals in the Central United States in 1936. This theory is called "Gray's Paradox".
It soon became clear that dolphin muscles had no special structure and certainly did not possess supernatural efficiency.
Therefore, according to current speculation, it must be the second reason that causes dolphins to swim at high speeds.
Is it a physical form? Some speculate.
That is not the case.
Scientists have made a dolphin model that is exactly the same as a real dolphin in terms of body shape and surface. The model is also equipped with thrusters that have the same thrust as the dolphin's tail fin.
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 dolphin skin is divided into two layers, the upper layer, which is the outer layer, is very elastic; the lower layer, which is the inner layer, also has good elasticity.
When the upper layer of skin is subjected to water pressure, it becomes uneven depending on the degree of water pressure.
When a dolphin runs at high speed, the turbulence caused by the vibration of its body will be adjusted by the changes in the unevenness of its skin, which can greatly reduce resistance.
Extremely magical.
In addition, although dolphins may look cute, they firmly occupy the top of the marine food chain and their fighting power is much stronger than most people think.
Sharks are the most ferocious fish in the ocean, known as the "wolves of the sea". They feed on injured marine mammals, fish and carrion, eliminating the weaker members of the animal world. They have few rivals 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 difficult for sharks to bite dolphins, but it is very easy for dolphins to attack sharks.
Although large dolphins are not as flexible, they can use their strong bodies to knock sharks off their feet.
You should know that once a shark is knocked over, it will fall into "tonic immobility" and fall asleep.
In biological taxonomy, sharks belong to the subclass Elasmobranchia of the class Chondrichthyes.
Their bones are made of cartilage and connective tissue. Although they are elastic, strong and durable, their density and hardness are far lower than that of real bones.
In addition, sharks do not have ribs, so the lower sides of their bodies and abdomen are the weakest parts of their bodies.
Dolphins are aquatic mammals with hard upper and lower jaws and a protruding snout that is like a sharp spear.
When the two really engage in a life-and-death fight, the dolphin will not let go of the shark's weaknesses.
Just like poking through wet window paper with your fingers - as long as the speed and force are right, the dolphin's spear-like snout can even pierce directly through the shark's body, causing fatal damage to the shark.
Moreover, there is another creature in the dolphin family who can be called the "King" in the shark world - the killer whale.
Killer whales are to the shark world what Chinese table tennis is to the international table tennis world. They are at the top of the pyramid, with a difficulty level beyond hell or even purgatory.
Basking sharks, tiger sharks, porbeagles, and sixgill sharks would all be scared to death if they met killer whales.
Although the Niugang trevally is not covered with cartilage and connective tissue, its abdomen is just as soft and has sharp spears, so it is not afraid of dolphins that swim at extremely high speeds.
In Bifang's perception circle, when the Niugang trevally appeared again, its speed had dropped significantly and it was floating quietly in the water.
Bifang gripped the harpoon tightly and slowly approached. The closer he got, the clearer his perception became. He could feel the bumpy holes on the body of the Niugang trevally, as if it had been repeatedly pierced by a spear.
As if sensing Bifang's approach, Niugang Wan tried to escape, but a spear suddenly pierced through Niugang Wan's eyeball and hit his brain directly. The already seriously injured Niugang Wan died on the spot.
After getting rid of the Niugang trevally, the dolphins seemed very happy and kept swimming within Bifang's perception circle.
It's a bottlenose dolphin.
Previously, the Niugang trevally and the dolphin were fighting so fast that Bifang didn't have time to sense them carefully. Now he finally saw what kind of dolphin it was.
It is the most common bottlenose dolphin in the aquarium, also known as the sharp-nosed dolphin and bottlenose dolphin. It is mainly distributed in major oceans in temperate and tropical zones, including the Yellow Sea and Bohai Sea in China.
It has a long snout, a short mouth, and a fissure in its mouth that makes it seem like it is 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 unlikely to live past 50 due to greater living pressure.
This type of dolphin is very intelligent, has self-awareness, strong emotions, and even strategy.
Some people believe that the intelligence of dolphins should be ranked ahead of chimpanzees and second only to humans.
The bottlenose dolphin in front of us is quite large, more than two meters and three meters tall, and its weight is definitely over three hundred kilograms. With such a large size, it should be a male.
Two meters three and three hundred kilograms. Compared with it, the Niugang trevally, which is only about one meter six and seventy kilograms, is nothing at all, just a small fish or shrimp.
No wonder it was solved so easily.
Watching the dolphins swimming around him, Bifang couldn't help but reach out and touch them.
As a professional diver, it should be a basic rule not to touch creatures in your hands casually. Perhaps a little human dandruff can cause damage to the underwater ecological environment.
Bifang's fingers touched the swimming dolphin. The bottlenose dolphin seemed very calm. Bifang pressed hard and could feel through the diving suit that the dolphin's skin was as smooth as silk and as textured as a sponge. It was extraordinarily beautiful and had excellent texture.
After waiting quietly for a while, another streamlined creature broke into Bifang's perception circle.
It was another bottlenose dolphin, also swimming around Bifang.
Male bottlenose dolphins usually live alone or in a small group of 2-3. They will only join other large groups of female bottlenose dolphins for a short period of time.
It is worth mentioning that the members of a bottlenose dolphin group are very attached to each other. If one individual is injured, the other members do not escape, but surround the injured companion and are reluctant to abandon him. They are an extremely compassionate species, and every one of them is like this.
From this point of view, dolphins are much smarter than humans.
Dolphins are second only to humans in intelligence on this planet.
Its brain weighs almost the same as that of humans, about 1.5 kilograms.
Humans have the highest brain-to-body ratio of all animals on Earth, at about 2%, while dolphins rank second at about 1.5%.
In addition, the dolphin brain has 18 billion neurons, which is more than the 13 billion neurons in humans.
Therefore, dolphins are far superior to other animals in terms of comprehensive brain data indicators, and are second only to humans.
Dolphins can use ultrasound to sense the bone structure of the human body and thus determine whether the other party is human.
They often rescue humans who fall into the water and lift drowning people to the surface to breathe, just like rescuing their own companions. They will also fight with sharks to save humans.
In order to study dolphins, humans conducted various experiments, one of which was a secret experiment that was not exposed 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 filled with water and let a female researcher named Margaret live with Peter. They were together 24 hours a day, eating, sleeping, studying and entertaining together.
This will allow Margaret to teach Peter to speak English like a mother teaches her child, and allow it to hear and understand human language.
Although dolphins do not have vocal cords, they can use the blowholes on the top of their heads to make sounds.
Peter the dolphin showed amazing learning ability. In less than two weeks, he learned to say numbers such as "one, two, three", simple greetings such as "hi, hello", and eventually learned more than 700 English words.
What is incredible is that Peter is not simply "parroting" because when Margaret says "work, work, work" to him, meaning to ask him to study, he really understands and replies "play, play, play", telling Margaret that he does not want to study, he wants to play.
Even when Peter wants to eat fish, he will say "Fish in bucket" to Margaret, meaning he wants to eat the fish in the bucket.
However, as the experiment progressed, something unexpected happened.
Peter is becoming less and less willing to study and only wants to be close to Margaret. He uses various ways to attract Margaret's attention every day.
When Margaret left it to go to the toilet, Peter would become agitated.
When Margaret was on the phone with someone, Peter would yell into the phone.
Obviously, it was jealous.
Peter has fallen in love with Margaret, which makes the research team think that the experiment is developing in a direction they cannot control, so the experiment was terminated and they forcibly separated Peter and Margaret. Although Margaret is reluctant to leave Peter, she can do nothing about it.
When Peter found that Margaret no longer appeared, he became extremely angry. He kept swimming around in the pool, calling Margaret's name, and refusing to eat or drink.
A few weeks later, Peter dove under the pool and refused to come up to breathe, suffocating himself.
The breathing method of dolphins is completely different from that of other animals. It is absolutely impossible for humans to commit suicide by holding their breath because after suffocating and falling into coma, the body will instinctively let go of breathing.
But dolphins' breathing is controlled by the brain rather than the autonomic nervous system, so they need to actively manipulate their muscles with every breath.
This was a scientific view in the past, and people used it to explain why dolphins committed suicide by holding their breath, and it became widely circulated.
But Richard told Bifang that this was inaccurate.
Someone once used complex and complete anesthesia experiments to prove that dolphins' breathing can be both "automatic" and actively controlled.
They can commit suicide by suffocating themselves by closing their own spiracles.
So everything is proven.
This dolphin committed suicide for love.
What is suicide?
This is a complex issue. Modern science has made great progress, but we still do not fully understand why humans commit suicide, and the risk factors for human suicide have not yet been determined.
The American Psychiatric Association lists suicidal behavior as a "disorder requiring further consideration."
Even what constitutes suicide in humans is controversial—as much a matter of biology and psychology as it is of philosophy and semantics.
Some people even point out that even among humans, suicidal behavior is rare among pre-adolescents or children with developmental disabilities.
Human children are unable to comprehend the concept of suicide, and the intelligence level of the smartest non-human animals is unlikely to exceed that of human teenagers. It seems even more impossible to expect them to understand their own death and have the ability to carry out suicidal acts.
In Bifang's view, suicide requires the perpetrator to have self-awareness, understand the true meaning of death, and be able to perform a series of actions that he knows will lead to his own death.
Everything proves that dolphins have extremely high self-awareness.
Because this experiment involved ethical issues, the data and files were sealed at the time and have never been made public.
It wasn't until 2014 that the experiment was finally declassified.
Bifang slowly exhaled a bubble. He looked at the dolphin beside him, slowly clenched his fist, and all the muscles in his body were mobilized.
He punched the dolphin hard on the head.
You helped me, but I'm sorry I'm going to hurt you.
