As media reporters, they were very happy to be able to shoot the first scene today, but as an ordinary normal person, the camera equipment in their hands was a little shaky.

Faced with a large shark mouth full of terrifying teeth, the hairs all over the body stand on end.

It was as if the air was already filled with murderous rage.

However, Liu Wei's face did not show a little nervous look, but was very cooperative with their shooting.

They can only marvel.

This person's mentality is so scary!

Liu Wei stood in front of the bull shark's head and continued to popularize science: "Brothers, do you remember the electric sense we mentioned when we were popularizing science about the great white shark? Its head is distributed with an electrosensory organ called a Lawrence pot.

This organ, which also grows on bull sharks and other sharks, relies on the faint radio waves emitted by sensing their prey to determine the location of their prey.

In addition, sharks have an unusually sensitive sense of smell, but experiments in Australia have shown that great white sharks do not have a strong desire to track the smell of blood, but can turn it on to the bull shark's irritable personality.

Its sense of smell can smell a drop of blood diluted in every ten liters of water, and it is able to track the blood for kilometers to find the source of the blood as it spreads, and finally attack the blood source. ”

"That's an exaggeration!"

"It turns out that the bull shark is the real murderer!"

"Isn't it that you don't dare to go into the water if you have a wound?"

"Those girls who go to swim in the sea, if the eldest aunt suddenly comes, it will be over!"

"Laugh and cry, this barrage is the best!"

"Give up your seat to Xiu'er!"

Liu Wei couldn't help but laugh when he saw the barrage.

This year's netizens are really good.

After calming down, Liu Wei continued: "The most important question you want to figure out about the bull shark should be, why is it the only one that can survive in fresh water?

Scientists have found that bull sharks have developed the ability to regulate salt in their blood through hundreds of millions of years of evolution.

On the surface of its body, there is a characteristic organ called the rectal gland, which can choose to absorb or discharge salt according to the body's needs, and maintain the balance of salt in the body.

This mechanism can adapt to freshwater and highly salinated seawater, which other species of sharks do not have!"

The camera captures the back of a bull shark.

At this time, Box made a small opening in its back with a scalpel, and turned back to the members of the scientific expedition team, "Is the signal debugged?"

"Everything works!"

“OK！”

They then implanted a GPS chip into the shark's body and sewed it up with medical needles and threads.

Boxy got up and wiped the sweat from his forehead and smiled, "It's done! With precise positioning, we can grasp the life route of this bull shark and even detect its family members."

It is very important for us to study the freshwater sharks in the Amazon rivers!"

Liu Wei nodded, happy about it.

"Liu, thank you for your support of our work!" Box stretched out his hand.

Liu Wei shook hands and said, "It's a good effort!"

The Boxs expedition team prepares to re-release the bull shark into the Amazon River.

However, media reporters gathered on the shore raised doubts.

Since the bull shark likes to attack humans and often kills, why should it be released back into the river?

In their opinion.

This creature should be disposed of.

Liu Wei heard the doubts and expressed his understanding, which belongs to the thinking of normal people.

Box was only thinking about the mission that the expedition team had come to this time, and did not expect so much media attention.

He knows the mouth of the media, and if he doesn't give a reasonable explanation, the reports on the Internet will be exaggerated and varied.

"The bull shark is a protected animal in Brazil and is also a key focus of the World Wide Fund for Nature (WWF), and its current living environment is very unsatisfactory, which may be the reason why they enter the freshwater rivers in large numbers?"

Just the title of "protecting animals" is not bought by journalists.

Don't people need protection?

"The number of bull sharks killed by humans each year far exceeds their own breeding capacity, and many bull sharks are killed at a young age because of huge economic benefits.

In the market, bull sharks are known for their delicious meat, which can be processed into a variety of meat products by traders.

Its fins can be used as shark fins, and according to statistics, more than 38 million sharks are killed every year in the world, and 1.7 million tons of shark fins are consumed by humans.

In addition, because of the thick skin of sharks, they are targeted by leather merchants to use its skin to make leather products, and many luxury brands in the world purchase shark skin as raw materials in large quantities.

Its liver can also be processed into vitamins and oils, and the rest of the body is made into fishmeal!

Shouldn't we be engaged in some work of protecting bull sharks compared to our unbridled fishing and demanding?"

Box was distracted.

His eyes were ruddy, and his tone was tinged with a hint of anger.

Liu Wei could feel the emotion expressed by Box.

In fact, this in itself is a paradoxical issue.

If analyzed from a subjective point of view, the bull shark does threaten human life, but this kind of danger can also be avoided.

On the contrary, if we analyze the objective development of the natural world, the overflowing fishing behavior that human beings are engaged in now seriously violates the laws of nature.

Liu Wei did not express an opinion on this.

The reporters also fell silent and stopped asking questions.

Box quickly calmed down, smiled, and thanked the media reporters, "Thank you for your attention to this matter, we at the Latal Shark Committee, the world's most professional organization for freshwater shark research, will use the most professional means to manage it!"

After speaking, he turned around and walked towards Liu Wei, "Liu, we still need your help!"

"OK!", Liu Wei walked to the river diving area and waited for the shark to be released, and when he arrived, he said to the audience, "Brothers, Professor Box's words just now made me think of a thing, there are many men's health products in the domestic market with the title of bull shark, such as bull shark enlargement cream.

The bull shark has such a short temper, mainly because its ** ketones are very high and the hormone secretion is vigorous, so many health care product companies make a fuss about it.

As for whether these health supplements have any effect? I don't know, and I haven't tried it, I just want to remind all male compatriots that everything needs to be controlled, and the body is the most important!"

"I've used that supplement!

"Poof~, young and strong, no need!"

"For the elderly!"

"Hahahaha, the atmosphere is a little wrong!"

"This topic will stop here, no more discussions!"

De Ye and the staff of the scientific expedition team carried the bull shark to the shallow water, and Box said: "Liu, the next thing will be handed over to you!"

They all knew that the bull shark would become more irritable once it re-entered the water, and that it had just been implanted enough time to rest, and now it was full of energy.

Box believes that only Liu Wei can complete the release task at the scene.

It's too dangerous.

The group put the bull shark in the shallow water, and it immediately swung its body and began to struggle.

Liu Wei walked up, held the bull shark with both hands in the same way, and walked to the deeper water level.

The river overflowed his waist, and Liu Wei let go of his hand.

The bull shark's body slammed into the water, then swung a few times and rushed into the deep water.

Under the impact of a powerful force, Liu Wei sat down in the water.

got up and wiped his face: "Tai Nima is irritable!"
