First of all, in our impression, hippos should be harmless. You know, hippos are herbivores, and there seems to be no danger except for their large size. But what I want to tell you is that we usually see hippos in the zoo, such as pygmy hippos, and some friends may think they are cute.
Secondly, hippos in the zoo are very docile, but you should go to the wild, especially in Africa. According to relevant data, as many as 500 people in Africa die every year because of hippos. This is only official statistics, and some have not been counted yet. So, actually, the death toll may be higher. We need to know one thing, that is, in very backward areas, people simply don't realize that hippopotamus attacks should be reported to the government, and people often die and are buried directly.
Then, some friends may not understand why hippos attack people, because hippos don't eat meat. Do Africans catch hippos to eat? It's possible. But it's often what you do that makes hippos misunderstand that you want to be bad to them. For example, if you think the little hippo is cute and want to get close to it, the mother hippo will not think so at this time, and she will think that you are going to do something bad to the little hippo, thus getting angry and attacking you.
Don't think hippos are stupid. They attack very fast and their teeth are extremely sharp. Students who have seen hippopotamus teeth will probably have nightmares.
Finally, even if a hippo doesn't need teeth, it can easily crush an adult hippo by its own weight, because you know, an adult hippo weighs more than 2.5 tons! Do you know why hippos are called hippos? The number one deadly animal? Well, in short, when traveling to Africa, you must remember to stay away from hippos, as long as you look far away. After all, if you watch too much, you may be thought by hippos to have bad intentions towards them, and you may die in minutes.
