Sharks can smell the smell of flesh and blood at a concentration of 1 ppm (one part per million) in the water, and their sensitive sense of smell can smell the bloody smell of injured people and marine animals several kilometers away.
What a terrible sense of smell!
Of course, in addition to the sense of smell, sharks also have a sixth sense - sensing electricity. With this ability, sharks can detect weak electric fields several feet around objects. They can also sense vibrations caused by fish or animals 600 feet away through mechanical sensing.
There is a special network of cells in the shark's head that can detect electric current, called electroreceptors. Sharks use electroreceptors to hunt prey and swim freely in the water.
This is simply because shark electroreceptors contain two independent genes from neural crest cells.
This neural crest cell is an embryonic cell that forms various tissues in the early stages of embryonic development.
Human neural crest cells play an important role in the formation of human facial bones and teeth.
This suggests that neural crest cells move from the shark's brain to various areas of its head, where they develop into electroreceptors.
This is probably the shark's tactile system.
In addition to smell and touch, sharks also have two special senses. One is the accessory nervous system, which is a row of nerve endings distributed on both sides of the body. It allows sharks to sense any movement in the water; another special sense is the ability to detect subtle electrical charges emitted by other organisms, called the ampulla of Lorenz.
There are so many terrible prey-catching systems that are simply bug-like!
What prey can escape the shark's capture range?
He is simply a terrifying predator in the ocean!
Zhuang Ming was completely familiar with all this, so he was not surprised at all. He was also surprised that there were sharks in this area.
Knowing the awesomeness of these sharks, Zhuang Ming also knew the shortcomings of sharks very clearly.
When a shark swims, it mainly relies on its body to move forward like a snake and cooperate with the oar-like swing of its tail fin to propel itself forward. Stability and control mainly rely on the use of more or less vertical dorsal fins and horizontally adjusted pectoral fins.
Therefore, the shortcomings of sharks are clearly exposed, that is, many sharks cannot move backward at all, so they can easily get trapped in obstacles like gillnets, and once trapped, it is difficult to extricate themselves.
And sharks are slightly denser than water, which means that if they don't actively swim, they will sink to the bottom of the ocean.
As long as he can't swim without using any hands, the shark will be completely dead.
Therefore, the shark's tail fin, dorsal fin, and pectoral fin are all its weaknesses.
The group of sharks rushed towards Zhuang Ming at a speed that was difficult to conceal.
These sharks can sense Zhuang Ming's existence because Zhuang Ming's body has been baptized together, forming a strange bioelectricity, and this bioelectricity was captured by these sharks.
The hideous and terrifying mouth opened in the water and swam quickly towards this side.
The extremely sharp teeth can be seen from a distance.
Even in the sea, it still emits a terrifying cold light.
Likewise, Zhuang Ming did not leave. Instead, he surfaced and quickly exchanged a nutritious meal from the system. At the same time, he increased his oxygen intake to restore his physical strength. The Tang Dao in his hand was already ready, and he was in the fastest state. Adjust the speed to the best, calculate the time, dive into the water again, and take the initiative to attack the shark!
...
The leading instructor, Gui Shou, and the other instructors stared at this scene in stunned silence, unable to say a word at all.
Zhuang Ming never uses two swords to kill a shark.
Zhuang Ming is like a swimming fish, extremely flexible.
Zhuang Ming's body shape actually became an advantage compared to the shark's huge size!
Even though it felt like Zhuang Ming didn't exert much force, Zhuang Ming's figure had already flown far away, as if it were a big crucian carp, very fast and much more agile than a shark.
I saw Zhuang Ming's figure suddenly rising into the sky directly from the siege of several sharks, like a fish jumping over a dragon's gate.
The shark next to him, which was significantly stronger and larger than the other sharks, suddenly rose directly from the sea and bit into Zhuang Ming.
The smelly bloody mouth made people sick. Zhuang Ming's raped and powerful body seemed to pause in the air for an instant, and the Tang Dao in his hand suddenly disappeared without any warning.
"Ang~"
The roaring sound coming from the throat of the big shark is frightening.
But the sound suddenly stopped.
The shark's flat and slightly pointed mouth suddenly exploded.
Wow~~~
呲呲~~~
Biao shot out brilliant blood, white shark meat and a small brain that was cut in half.
As for the middle, there are shark's internal organs and some black meat.
A shark several meters long was split in half.
It's like half blooming, so beautiful.
He gently tapped the shark corpse with his toes, and with a handsome and unrestrained somersault, he jumped out of the shark's circle.
Bang~
Because of Zhuang Ming's disappearance, those sharks had no time to dodge, and they had no chance to dodge.
They collided directly and made a huge noise.
It happened that four sharks collided with each other, and they were knocked unconscious by the direct impact. They lost their balance for a while and ran around in the sea.
Huge splashes of water flew high above the sea level, and the swimming routes of the four sharks also became crooked, like drunken men.
The shark in the air also fell directly into the sea water, instantly dyeing the sea area red.
And those shark companions instantly opened their bloody mouths again, biting their dead companions.
"Wow~"
Zhuang Ming calmly fell into the water, and the splash was almost negligible. Even in this state of jumping high, Zhuang Ming could still control his body, and there was a hint of ridicule at the corner of his mouth: "In the final analysis They are just a group of creatures without intelligence, acting only on instinct."
kill!
kill!
kill!
Zhuang Ming forgot everything and only kept killing. The sparring partner of this group of sharks was so much better.
There are so many of them, this kind of overlord in the sea makes Zhuang Ming feel like he is dancing on the tip of the god of death.
Adrenaline rush!
The Tang Sword became more and more smooth in the sea water, reaching an extreme!
At this moment, Zhuang Ming seemed to clearly feel the texture of the sea water. The Tang knife passed through it, following the texture, more relaxed, faster in the water, and the knife became more fierce!
Why do people need to constantly change various stimuli when training?
The sparring partner also needs to be changed!
Because people are inherently bored, and it is normal for human beings to like the new and dislike the old. Just like behind every goddess, there is a man who is bored with her.
Therefore, people need the stimulation of various new things and will become more excited.
Like now!
Shark is Zhuang Ming’s newest sparring partner!
And there is an endless stream of them, one after another, rushing forward, fearless and fearless!
Where can I find such a sparring partner?
Well, this is the kind of sparring partner who wants to eat him!
