Chapter 783: Fall down

Liu Wei: "We mainly mention two speeds of poisonous snakes, attack speed and movement speed.
The speed of the attack is no longer talked about. In the viper family, the performance is quite satisfactory.
Mainly talk about its speed of movement. In the documentary "Fatal Black Mamba" and many domestic Internet encyclopedias, it is called the world's fastest viper.
Long-distance activities can reach 16㎞/h, and short-distance sprints can exceed 20km/h.
What is this concept?
A simple calculation shows that if the black mamba is placed on the 400-meter track and field, the sprint distance can be estimated.
It takes 13 seconds to run 50 meters at the fastest speed.
Everyone should have taken the sports exam for the high school entrance examination, please tell us your sports score for the high school entrance examination! "
"I am only more than 13 seconds in a hundred meters!"
"One hundred and fifty kilograms of fat people said that they could run 13 seconds in 50 meters!"
"That's it? The fastest viper in the world?"
"No! It's too slow!"
Liu Wei smiled and said: "The authenticity of these data has yet to be verified. British scientists have personally conducted experiments and recorded the short-distance sprint speed of a black mamba under full anger, only reaching 11km/h, even if It is full of energy and full exertion, and it is impossible to exceed the speed of 16km/h.
In nature, most land creatures move faster than it.
Putting it in the family of venomous snakes is indeed a leader, but we all know that the deadly weapon of venomous snakes is its venom.
Movement speed may only play a role in chasing prey and escaping.
This also determines the difference between the hunting situation of viper snakes in Black Mamba and other cobras.
In the recipe of Black Mamba, 81.48% are mammals and 14.81% are birds, it is better at catching smaller prey.
Black Mamba will recognize the strength of the prey when hunting. If it is a weak prey, it will bite to death until the venom produces the suffocation of the prey, and directly eat the prey.
If the prey is strong, it will bite the prey and loosen its mouth, wait for the venom to attack, rely on its own speed to track the prey, and then swallow.
In my opinion, the speed boasted in the documentary has not been too dazzling in actual combat! "
Liu Wei glanced down at the black Mamba snake in his hand. "Normally someone will compare it with the king cobra, one known as the world's longest and longest viper, and one known as the world's second longest viper.
This pointless comparison mentions the danger of Black Mamba to some extent.
The king cobra we caught in the tropical rain forest of Yunnan is more than 4 meters long. The longest confirmed king cobra is 4.71 meters long. King cobras more than four meters are not very common, but there are also many , More than three meters can be said everywhere.
The maximum length of Black Mamba proved to be 4.31 meters, and then individuals found by humans more than four meters are handful, even those more than three meters are difficult to see, most of them are between 2.3 and 2.9 meters. This one is about 2.7 meters.
From the length point of view, King Cobra has already dumped it, not to mention that in terms of body stiffness, Black Mamba and King Cobra are not at all a heavyweight player! "
"In my eyes, the king cobra is always the boss of the viper!"
"I also like kc!"
"If it's not the boss, I don't know Black Mamba at all!"
"Anchor, there is no need to blow one down! Black Mamba is useless by what you said!"
However, many audiences questioned Liu Wei's professionalism.
Liu Wei smiled faintly: "Let's take a look at his fatality rate. Data show that in the seven bite cases of the Black Mamba snake, all seven patients died, with a fatality rate of up to 100%.
Does it sound scary? More deadly than the world's first poisonous snake inland Taipan snake!
But what I have to say is that the fatality rate is closely related to the number of bite cases. Taking only seven death cases to calculate, it is very one-sided. In fact, there are many cases of black Mamba bite cases.
In addition, the medical conditions in Africa need not be mentioned by me. I want to be clearer than everyone. In addition, African indigenous people do not have the awareness of protection in this regard, and it is easy to produce death cases. Many people are bitten by Black Mamba, or they are treated as accidents. For minor injuries, either find a wizard from the tribe to dress up casually, and treat the symptoms but not the cause.
To give a practical example, there was a black mamba bite incident in Tanzania. The patient went to the local hospital with better medical conditions for eighteen hours after being bitten and died.
On the one hand, I can only admire the physical quality of this black uncle, who can carry it for so long, on the other hand, they show their lack of crisis awareness in the event of a snake bite.
So the high fatality rate of Black Mamba deserves further study! "
Many audiences gave a voice of approval.
Liu Wei's analysis is very objective.
The probability is closely related to the size of the cardinality. The larger the cardinality, the greater the strength, the probability cannot reach 100%.
This point, the audience playing the glory of the king has a deep experience.
Liu Wei took out the poison cup during the discussion of the audience, without hesitation, and sent it directly to the mouth of the black mamba. "Its fangs are very fragile. I need to be gentle and avoid hurting it!"
The Black Mamba didn't feel Liu Wei's tenderness, but he was still very angry, biting through the film of the poison cup, the venom was discharged very quickly.
But not as much as imagined.
Liu Wei shook the poison cup in his hand, "The detox amount of the Black Mamba is actually very scary, basically above 100mg, and the highest can exceed 400mg, but it has a habit, and generally does not put venom in one shot. After arranging, it is beneficial to launch multiple attacks on the prey.
Now let me give you a detailed look at the venom of the Black Mamba snake to see if it is as scary as many viewers think it is?
First of all, the venom component, the iconic toxin of the Cobra family venom is the neurotoxin. The Mamba family has a special neurotoxicity, the venom neurotoxicity. This toxin accounts for a very large proportion in the black mamba venom, but the toxicity is not Not Powerful.
It is precisely because of this that it lowers the venom effect of Black Mamba.
Its best subcutaneous ld50 value can only reach 0.25mg/kg, and its normal performance is 0.3mg/kg. In terms of toxicity, the inland Taipan snake is ten times its.
Half of the lethality is manifested in the known viper, and Black Mamba can’t even enter the top 20.
Let's compare it with the venom of venomous snakes that have been popularized before. Many venoms of venomous snakes will have buff blessings, which will cause serious additional damage to the human body, such as blood clotting and bleeding.
However, Black Mamba's venom lacks hemorrhagic coagulation activity, has almost no lipase activity, and has very low protease activity, which means that Black Mamba has no additional venom-enhancing ingredients and can only rely on the venom toxin itself.
In contrast, it has lost to many venomous snake bosses.
but……"
Liu Wei showed an unbelievable smile.
"I knew there was a turning point!"
"Although the documentary has exaggerated elements, it is not so weak!"
"I just want to hear but!"
"But it can kill people easily!"
Liu Weidao: "The venom of Black Mamba also has advantages that other vipers do not have!"
