In our impression, we always think that the number of times poisonous snakes hurt people is not much, especially the small partners in the north, have not even seen wild poisonous snakes, because there are fewer varieties of poisonous snakes in our country, there are only more than 50 species in the country, and most northern cities even have only one or two kinds, so we feel that poisonous snakes are far away from our lives. In fact, China is bitten by poisonous snakes every year there are thousands of people, most of them are in the middle of Guangxi, Guangdong, Fujian, Jiangsu and other places, of which the most injured is the short-tailed pit viper, according to statistics a total of more than 20,000 people, even if it is such a high frequency of injuries, in the world, it is not ranked at all.
We have all heard that snakes will hibernate, in fact, not all snakes need to hibernate, only living in a low temperature environment, snakes will find holes to spend the winter, only half a year of time out to forage, reproductive ability will also decline, because the north of our country is not suitable for the survival of poisonous snakes, so the number is so rare. But the southern cities are different, snakes do not have the conditions for hibernation, even in winter will be very active, still predation and reproduction, venomous snakes are more and more, the number of wounded people is high, which is also the reason why venomous snakes are mainly concentrated in southern cities.
And the most injured venomous snake in the whole of Asia is the round spot viper, which is very small in China, mainly living in Thailand, India, Indonesia, Sri Lanka and other Southeast Asian countries, the number of injuries every year can reach tens of thousands of times, which is about ten times that of Our country, and 75% of the snake injuries in Sri Lanka are caused by round spot vipers. It is also a well-known "kidney deficiency snake", just for its serum, there are as many as five kinds of world, it can be seen that its harm is great, the fatality rate is high, the injured often have symptoms of kidney failure, even if it is cured, it may not be able to have children in the future, very lacking in morality, let people smell frightened.
However, compared with the venomous snakes in Africa, it is still a small witch, Africa is the most distributed place in the whole earth, and there are many well-known venomous snakes, such as black mamba, Gabonese viper, golden cobra, even people who do not understand snakes have heard of their big names, but these snakes are only famous, and the number of injuries is not much. Africa has a dry and hot climate, is the paradise of poisonous snakes, here live as many as a hundred species of poisonous snakes, they are evenly distributed, can be seen in various countries, any one can easily take people's lives, of which the most hurtful is the number of "drum belly sizzling viper".
I don't know if you found it, in the number of vipers in the world, all of them are vipers occupy the top of the list, like China's short-tailed viper, it is also a kind of viper family, belonging to the viper family viper subgenus, which is what we often call pit vipers. Vipers are large in size, have a large amount of venom, and most of them are blood toxins, which are very painful after biting, like China's well-known five-step snake, the original spearhead viper, the Mangshan soldering iron head, the bamboo leaf green, and the round spot viper all belong to the viper family. Moreover, the smaller the size, the more people are injured, like the short-tailed viper than the five-step snake hurts several times more people, because it is small, only less than a meter long, and it has become its biggest advantage.
Because the biggest feature of the viper family is to hide the body, they often hide in the fallen leaves, rocks, dry grass and motionless, as long as someone has no intention of approaching, it will suddenly come out to attack humans, making people invincible, because small snakes are not easy to find, people are easy to relax their vigilance, so that they have repeatedly succeeded. Like the drum-bellied viper, it is much smaller than the Gabonese sizzling viper, rhinoceros sizzler, rhinoceros viper, rhinoceros viper is much smaller, on average only about a meter, and relatively thin, often lying in the grass on the side of the road, looking for frogs and other food, if someone passes by, it will suddenly jump out and bite you.
This is not alarmist, this snake can really jump up, its muscle strength is very strong, using the back half of the body to exert force, it can take off in the air, jump forward a distance of about a meter, which is also its winning magic weapon for catching prey. And the drum-bellied viper is particularly capable of giving birth, can give birth to hundreds of small snakes at a time, and is also the most capable venomous snake in the world, and its descendants are spread to every country in Africa, whether in deserts, plains, woods and coastal areas. Its sheer number and wide distribution have made it the most injured venomous snake in the entire African region, adding up to more than all the venomous snakes combined.
Do you think it's a champion? Far from enough, even if it is such a "record", it is not ranked first in the world, and the most injured poisonous snake in the world is called "saw scale viper". Small partners do not have to worry, this snake does not exist in China, mainly distributed in Africa, in the Middle East, India, Pakistan and other countries are also distributed, and the number is very large, in India and the round viper, Indian cobra, Indian ring snake known as the "four kings", and saw scale viper is the weakest, but it is the first of the four kings, because its number of injuries, fatality rate are far more than other poisonous snakes.
And it is one of the smallest vipers, only about 0.5 meters, but was selected as the world's most threatening to people of the venomous snake, its toxicity test for intraperitoneal injection ld50 = 0.25-1.0mg / Kg, the toxicity is not strong, and the fluctuation is very unstable, even ordinary cobras are not comparable, from the toxicity alone it is still very weak. Because of its small size and the amount of detoxification is not outstanding, it can be said that it is the lowest existence in the viper, with an average of only 10 mg, which is ten times or even a hundred times worse than most vipers, and people can't help but wonder, why can it become such a deadly poisonous snake?
Venomous snake injury poison and venom volume is not the only assessment criterion, but also depends on the toxicity of the ability to harm human body functions, its venom has a strong coagulation ability, can make patients appear "diffuse intravascular coagulation", referred to as DIC, if this symptom occurs, the mortality rate can reach 30%-80%. Among patients bitten by sawfish, 80% of them will have vascular coagulation symptoms, so that the coagulation factor is rapidly depleted, which causes bleeding throughout the body, causing damage to multiple organs of the human body, and irreparable serious consequences, only timely injection of serum can save life.
Saw scaled vipers are widely distributed, numerous, and very good at hiding their size, often hiding under sand and gravel, and are particularly hot-tempered and aggressive, making defensive postures whenever someone approaches. Most of the patients who bite are countries with underdeveloped medical treatment, and they cannot receive treatment in time, which leads to a sharp increase in mortality, and it has become the most injurious poisonous snake in the world.
