At present, the most poisonous snake in the global academic circles is the inland Taipan snake, also known as Taipan snake. The LD50 (lethal dose of 50%) of snakes ranks first. Lethal dose 50% refers to the minimum toxic/drug dose that can cause half of the death of experimental animals, usually expressed by the logarithmic value of lethal dose of drugs. It should be noted that the smaller the LD50 value, the greater the toxicity, that is, the toxicity is inversely proportional to the LD50 value, because this is the minimum dose that can cause half of the experimental animals to die. Experimental animals usually use mice or rats, so the value of LD50 is also relative to mice. The LD50 of Taipan snake injected subcutaneously in mainland China is 0.025 mg/kg, and the detoxification amount is about 44.0-110.0mg. Many people think that the most poisonous Belcher sea snake mentioned before intramuscular injection of LD50 is 0. 1.55 mg/kg. The lower the LD50 value, the greater the toxicity, but the horizontal comparison of the same infection route must be carried out. At present, the LD50 of Belcher sea snake by intramuscular injection can't be compared with that of inland Taipan snake by subcutaneous injection, so Jambers Chercher sea snake is ahead of other snakes. The intramuscular LD50 of the salmon was 0.09 mg/kg. The LD50 of intramuscular injection of Hydrophis melanosoma was 0.082 mg/kg, which was more toxic than Belcher. Therefore, Belcher's throne as the "No.1 poisonous snake in the world" is definitely untenable. Then the LD50 of subcutaneous injection was compared with that of the smooth swordtail sea snake, the black ring sea snake and the inland Taipan snake, and the LD50 of subcutaneous injection of the smooth swordtail sea snake was 0.264mg/kg；. The LD _ (50) of the subcutaneous injection of the black ring sea snake is 0.11mg/kg, which is quite different from the inland Taipan snake's 0.025 mg/kg. From this point of view, Belcher sea snake is not only the most poisonous snake in the world, but also the highest in toxicity among sea snakes. How much venom does the inland Taipan snake need to poison a person? Let me give you an example. Inland Taipan snake LD50 0.025mg/kg, my weight is 80KG. In other words, it only takes 2mg to poison me, and its detoxification amount is about 44.0- 1 10.0mg. In other words, if I am bitten without serum, I will die and basically say goodbye to the world. Let's start with the most poisonous snake in China, the silver ring snake. Many people have been misled by documentaries. In the eyes of many people, Chen Yuanhui's documentary thinks that the original spearhead of Mangshan Mountain (formerly known as Maoshan Welding Head) is the most powerful poisonous snake in China, but it is actually wrong. The most poisonous snake in China is the Bungarus multicinctus. This is universally acknowledged. The LD50 of Bungarus multicinctus ranked seventh. In other words, the toxicity of snakes ranks seventh in the world. The toxicity of Agkistrodon acutus in Mangshan is far from that of Agkistrodon multicinctus. Fortunately, the silver ring snake has a gentle personality. Although highly toxic, it is not easy to bite, and it is nocturnal. Bungarus multicinctus is a kind of snake of Cobra family (inland Taipan snake is also Cobra family), and it is a neurotoxin. After being bitten by a silver ring snake, it won't be as painful as a poisonous snake family. Many people don't even know that they were bitten by it and then died in their sleep. Bungarus multicinctus has short fangs, so it doesn't necessarily inject venom when it bites (venom is also very important to it, and human beings are not its food, and it doesn't want to waste venom, so it often bites it dry to scare off enemies. )
