Why do you say Liao is a good snake catcher?

Cobra is one of the most poisonous snakes in the world. Cobra is neurotoxic, which mainly damages human central nervous system. People bitten by cobras will die in a few hours if they are not rescued in time. If you are bitten by a king cobra, you need first aid, or you will die in a few minutes. Cobra is so powerful, but it has natural enemies. The natural enemy of snakes is jackals. Mongoose is a mammal, belonging to a subfamily of Carnivora. There are two kinds of animals in China: a mongoose that eats crabs is about the size of a domestic cat; The other is called red-cheeked mongoose, which looks like a weasel. This animal has a slender body, short limbs, a pointed head and a long tail, and its whole body is covered with very fluffy hair. Although they are small in size, they are extremely fierce in character. They specialize in preying on all kinds of weak animals, especially the little red-cheeked mongoose, and they are better at catching snakes. No matter how powerful a poisonous snake is, it can't escape its sharp mouth. Indian meerkats also eat cobras. When Liao struggled with the cobra, Liao stood up in a long hair, demonstrated to the cobra, and began to jump on both sides of the cobra, looking for opportunities, and then suddenly jumped up and pounced. This can often accurately bite the cobra's neck, so that the cobra can't turn back and bite. If it can't bite the neck at once, it will bite the snake's back. In this case, the mongoose will always jump up and duel with the cobra until the cobra is exhausted and unbearable. At this time, it unexpectedly bit the cobra's head and neck and ate it. Why doesn't Liao get poisoned after eating poisonous snakes? This is still a problem that scientists study. Some people think that mongoose's ability to resist snake venom comes from heredity; Some people think that Liao often eats some wild herbs; Some people think that there are special substances in Liao's digestive tract, which can decompose and destroy the toxins eaten and make them lose toxicity. What it is remains to be further analyzed.
