"Huh~, dense phobia retreats!"

"So many killer bees stung it, doesn't it hurt?"

"The hemp that people eat is fragrant!"

"This is the strong man at the top of the food chain!"

Liu Wei was also a little frightened.

There are so many killer bees, if they fly towards him and have no auxiliary tools to drive them away, they will definitely kill him.

However, Brother Pingtou looked like he didn't have enough to eat and didn't want to leave.

"Brothers, Brother Pingtou is an all-terrain athlete, and there is no place on the grassland that he can't reach.

Its claws are thick, longer than the claws of black bears, we know that black bears are famous tree climbers, relying on thick and powerful claws can drive hundreds of pounds of body to climb trees.

The weight of the flathead is only one-tenth of that of a black bear, and these trees on the grassland can't beat it at all.

It usually squats around the trees at night, because the leopard that moves on the grassland will carry the gifts it has caught to the trees, and when the leopard goes out for a walk, it will quietly climb the tree to steal food.

If it happens to run into it, it will not be frightened, take out its own courage and the spirit of dying to entangle with the leopard, relatively speaking, on the grassland, the leopard is one of the most feared opponents of the flat-headed brother, but it will not be restrained, so that the leopard can be easily subdued, often a long time of entanglement will make the leopard take the initiative to give up.

In addition to the trees, the rodents in the ground can't escape its appetite, and even creatures like porcupines covered with spikes will find a way to challenge it, and there are not many cases of predation, but more to drive away the porcupines and seize its burrows.

In its opinion, the porcupine's cave is much better than the one it built itself!

The bees we see in the crevices of the rocks today will not escape the fate of being harassed by it.

So here's the problem?

Where did it get the courage to be so presumptuous?" Liu Wei threw out the topic.

"That's right! With such a small stature, the strength and bite force are not strong!"

"It's not enough to rely on courage to run rampant and domineering on the African savannah!"

"Players with commendable courage have a tragic ending!"

"Is it really completely immune to snake venom?"

After Liu Wei mentioned it, the audience in the live broadcast room raised questions one after another.

Where did the flat-headed brother get the courage?

Liu Wei took advantage of the fact that he was still enjoying the food, and said in popular science, "Actually, when facing a strong opponent, Brother Pingtou does not have a strong desire to attack, and it thinks that making the most ferocious appearance can scare the opponent, which is a bit of a bluff."

Here's where its cleverness lies, bluffing can make opponents hesitate and then create opportunities to flee the scene.

In our human terms, its psychological tactics are very slippery!

However, it is not enough to rely on strategy and tactics to escape from the mouths of top predators on the grasslands such as lions and leopards many times.

It also has a comprehensive set of defense mechanisms.

One is physical defense, here I will combine Pingtou's anti-drug ability to give you popular science.

The physical defense mechanism is simple, the flat-headed brother's fur is hard and thick, the hair can stand upright, very piercing, this coat can resist the bite of a lion leopard, and it can also resist the puncture of a poisonous snake's fangs.

There are three main kinds of highly venomous snakes that are active in the grassland, one is the ventral snake family, the other is the cobra family, and the other is the viper family, the fangs of these three poisonous snakes are very fragile, and it is difficult to bite through the fur of the flat-headed brother, so when it preys on the poisonous snake, many of the attacks launched by the poisonous snake are ineffective.

Large carnivores such as lions and leopards have great strength and bite power, but they cannot show their skills in front of the flathead.

Because the fur and muscle tissue of the flat-headed brother are not connected together, which means that even if the lion bites its body, it cannot control its body, and the muscle tissue will still move at will.

Even if you can't kill a strong opponent, you will still make it draw.

Therefore, although the flathead brother does not have the ability to kill the lion leopard, it has a defense system entangled with it, and it may take them an hour or two to kill a flathead.

In contrast, it is better to catch foods that are larger and can satisfy your appetite. ”

"A strong opponent is not afraid, the most afraid of a difficult opponent!"

"It sounds like I don't think it's worth it for a lion to provoke it!"

"Brother Pingtou still has something!"

Liu Wei then said of popular science: "Let's talk about another defense mechanism - chemical defense.

First of all, I'm not sure, and I can even say that the results of the current experiment do not prove that Pingtou is immune to all venomous snakes.

After all, there are too many species of venomous snakes in the world, and the venom toxins are different, the amount of toxin is different, and the living environment is different.

As far as the African savannah where it lives, it is resistant to the venom of poisonous snakes in its environment

According to experimental research at the University of Minnesota, Pingtou's muscle-type nicotinic ethanol choline receptor has mutated and evolved the ability not to bind to neurotoxins!"

"What's that?"

"Anchor, please say it again, it's too long, I can't remember!"

"You don't understand, it's awesome anyway!"

"The medical student said he could understand, Ah Wei, you go on!"

Liu Wei smiled: "In the Minnesota experiment, the main ingredient in the cobra venom was used, α_ nerve poison, and when I popularized the king cobra, I have already talked about the α _ nerve venom in detail, so I won't mention it here."

Experiments have shown that the muscle-based nicotinic ethanolcholine receptors of organisms such as flatheads, wild boars, and hedgehogs do not bind to α neurotoxins, meaning that this toxin has no effect on their bodies.

In addition, Pingtou can also neutralize metalloproteinase, and metalloproteinase is the main component of hemorrhagic toxin, so it is resistant to neurotoxins and hemorrhagic toxins, but the resistance is limited, experimental data show that Pingtou can bear the upper limit of snake venom does not exceed 100mg of dry poison, this amount is very amazing, only a few poisonous snakes can eliminate such a large dose of dry poison at one time, for killing an adult, it is easy.

You should have watched the documentary "The Ultimate Honey Badger", when it was bitten by a poisonous snake, it lay on the ground and fell asleep, and then woke up, not as rumored on the Internet, there was nothing to do after sleeping, but the amount of poisonous snake detoxification at that time, to be precise, the amount of venom injected into Brother Pingtou's body was close to the upper limit of 100mg, so that it was in a short-term fainting state.

Bodily functions need to work for a long time to resist the toxic effects of venom.

The snake that bites it in the documentary is the bulging-bellied giant viper on the list of venomous snakes in Africa, ranking among the top five in Africa for toxicity and extremely lethal. ”

"I just said that it is impossible to be bitten by a snake, and it will be fine if you sleep!"

"It's too fierce on the Internet!"

"Thank you Ah Wei for solving my doubts!"

"I was still wondering if I was bitten by a poisonous snake and I also lay down on the ground and fell asleep, would I wake up and be fine?"

"Just wait for your family to collect the body!"
