Liu Wei: "We mainly mention the two speeds of poisonous snakes here, attack speed and movement speed.

The attack speed is not much to talk about, and in the Viper family, the performance is decent.

Mainly talking about its moving speed, in the documentary "Deadly Black Mamba" and many domestic online encyclopedias, it is called the fastest poisonous snake in the world.

Long-distance activities can reach 16 kmh, and sprint sprints can exceed 20 kmh.

What is this concept?

A simple calculation can be concluded that if the black mamba snake is placed on the 400-meter track and field, the sprint distance is measured.

It takes 13 seconds to cover the 50 meters at the fastest speed.

Everyone should have taken the physical education test of the high school entrance examination, please tell us your physical education results of the high school entrance examination!"

"I'm only a little more than thirteen seconds in 100 meters!"

"A little fat man of one hundred and fifty pounds means that fifty meters can run for thirteen seconds!"

"That's it, the fastest venomous snake in the world?"

"No, it's too slow!"

Liu Wei smiled: "The authenticity of these data remains to be verified, British scientists have personally done experiments, recording a black mamba snake in the case of being completely provoked short-distance sprint speed, can only reach 11kmh, even if the physical strength is abundant, full play, it is impossible to exceed the speed of 16kmh."

In nature, the vast majority of land creatures move faster than it.

In the big family of poisonous snakes, it is indeed a leader, but we all know that the lethal weapon of a poisonous snake is its venom.

Movement speed may only play a role in chasing prey and escaping.

This also determines the difference between the hunting of venomous snakes in the black mamba and other cobra families.

In the diet of the black mamba, which is 81.48% mammalian and 14.81% bird, it is better at catching smaller prey.

When hunting, the black mamba will distinguish the strength of the prey, if it is a weak prey, it will bite to death until the venom is effective, the prey suffocates to death, and directly devours the prey.

If the prey is strong, it will bite the prey and let go, wait for the venom to attack, rely on its own movement speed to stalk the prey, and then swallow it.

As far as I've seen, the speed boasted in the documentary isn't too impressive in actual combat!"

Liu Wei glanced down at the black mamba snake in his hand, "Usually people compare it with the king cobra, one is known as the world's largest and longest venomous snake, and the other is known as the world's second longest venomous snake."

This meaningless comparison mentions the dangers of the black mamba to a certain extent.

The king cobra we caught in the rainforest of Yunnan is more than 4 meters long, and the longest known confirmed king cobra is 4.71 meters long.

The longest length of the black mamba confirmed is 4.31 meters, and then there are only a handful of individuals above four meters found by humans, and it is difficult to see even more than three meters, most of them are between 2.3~2.9 meters, and the one in my hand is about 2.7 meters.

Judging from the length alone, the king cobra has already thrown it off, not to mention that in terms of the thickness of the body, the black mamba and the king cobra are not the same weight class at all!"

"In my eyes, the king cobra will always be the boss of the poisonous snake!"

"I like KC too!"

"If it weren't for the boss, I wouldn't know about the Black Mamba at all!"

"Anchor, there's no need to blow it up! Black Mamba is useless for what you say!"

There are still many viewers who question Liu Wei's professionalism.

Liu Wei smiled faintly: "Next, let's take a look at his fatality rate, some data show that in the seven bite cases of the black mamba, all seven patients died, and the fatality rate was as high as 100%.

Doesn't that sound terrifying? It has a higher fatality rate than the world's first poisonous snake, the inland Taipan snake!

But I must say that the fatality rate is closely related to the number of bite cases, and it is very one-sided to take only seven fatal cases, in fact, there are many more cases of black mamba bites.

In addition, I don't need to mention the medical conditions in Africa, I want to know better than everyone, plus the African indigenous people do not have this sense of protection, it is easy to produce death cases, many people are bitten by the black mamba, either as a little accident, or find a tribal wizard to bandage it casually, treat the symptoms but not the root cause.

As a practical example, there was a black mamba bite in Tanzania in which the patient died after being bitten 18 hours before going to a hospital with better medical conditions.

On the one hand, I can only admire the physical fitness of this black uncle, who can carry it for so long, and on the other hand, it reflects their lack of crisis awareness in the poisonous snake bite incident.

So the high lethality rate of the black mamba deserves further study!"

Many viewers voiced their voices in agreement.

Liu Wei's analysis is very objective.

There is a close relationship between the size of the probability and the size of the cardinality, the larger the base, no matter how strong the strength is, the probability cannot reach 100%.

This point is deeply experienced by the audience who play Glory of Kings.

When Liu Wei was discussing in the audience, he took out the poison cup, and without hesitation, he sent it directly to the mouth of the black mamba snake, "Its fangs are very fragile, I need to be gentle to avoid hurting it!"

The black mamba snake didn't appreciate Liu Wei's gentleness, and was still very angry, biting through the membrane of the poison cup, and the venom was discharged quickly.

But not as much as you think.

Liu Wei shook the poison cup in his hand, "The amount of detoxification of the black mamba snake is actually very terrifying, basically more than 100mg, and the highest can exceed 400mg, but it has a habit that it generally does not drain the venom at one time, which is conducive to launching multiple attacks on the prey."

Now I'm going to give you a detailed science popularization of the venom of the black mamba snake to see if it is as terrifying as many viewers think?

First of all, the venom component, the signature toxin of the venom of the cobra family is the neurotoxin, the Mamba family has a special neurotoxin, the tree poison neurotoxin, this toxin accounts for a very large proportion of the black Mamba venom, but the toxicity is not very strong.

It is precisely because of this that the venom effect of the black mamba is lowered.

Its subcutaneous LD50 value is the best and can only reach 0.25mgkg, and the normal performance is 0.3mgkg, in terms of toxicity, the inland Taipan snake is ten times more than it.

Half of the lethality is manifested in known venomous snakes, and the black mamba can't even make it into the top 20.

Let's compare it with the venom of poisonous snakes that we have popularized before, and the venom of many poisonous snakes will be blessed with buffs, which will cause serious additional damage to the human body, such as blood clotting, bleeding, etc.

However, the venom of the black mamba lacks hemorrhagic coagulation activity, the coagulase activity is almost none, and the protease activity is also very low, which means that the black mamba has no additional components to enhance the power of the venom, and can only rely on the venom toxin itself.

In contrast, it has already lost to quite a few venomous snake bosses.

But ......"

Liu Wei smiled incredulously.

"I knew there was a twist!"

"Although the documentary has an exaggerated component, it is not so weak!"

"I just want to hear about it, but!"

"But it can still kill people easily!"

Liu Wei said: "The venom of the black mamba also has advantages that other poisonous snakes do not have!"
