The toothpick bird and the crocodile are in a state of mutual assistance. The toothpick bird can help the crocodile clean its teeth and also inform the crocodile. The two are interdependent. Once the crocodile hurts the toothpick bird, the toothpick bird will no longer do anything helpful to the crocodile. In the end, the crocodile will also suffer. To put it simply, it is a win-win situation. It is better for everyone if we do not harm each other. If one party breaks its promise, both parties will have to pay the price. 1. Help each other

In fact, there are many such mutual-helping animals in nature. There are about 8,000-9,000 kinds of birds in the world, and more than 300 of them help other animals clean their bodies and even help feed them. The Egyptian plover and the crocodile are one of them, and they have a biological relationship. This kind of bird is commonly known as the toothpick bird. Its main function is to help crocodiles clean their teeth. When danger approaches, a warning will also be sent to the crocodile. Even if the crocodile closes its mouth, it will not swallow the toothpick bird. The reason is very simple, that is, the toothpick bird is useful to me, and I only asked the toothpick bird to help me after enjoying the delicious food. 2. Why don’t crocodiles eat toothpick birds

There are many reasons why crocodiles don’t eat toothpick birds. Personally, I think there are two main ones, namely, there is no need to eat and they are for their own sake. Generally, the toothpick bird helps pick teeth after the crocodile has enjoyed its meal. This is generally the case for animals in the wild. After they have eaten enough, they will not attack the prey around them. Moreover, too many food debris and parasites in the crocodile's mouth can cause dangers such as tooth decay and tooth loss. Just imagine what would happen if a crocodile had no teeth. So no matter from which aspect, the crocodile and the toothpick bird are in a mutually supportive relationship and cannot harm each other. 3. The law of birth

There is a scene in the movie "Highland War" where both South Korea and North Korea want to occupy a high ground. So the two sides fought a symbolic battle, no one would die, and everyone survived. Soldiers from both sides will also help each other deliver letters. But one day one party took out heavy weapons and hurt the other party. At this time, the opponent also launched a counterattack, and both sides could only suffer losses. This is the law of life. Once someone breaks it, he will be punished accordingly.
