Why hippos are not afraid of crocodiles is because of many reasons. Although crocodiles are carnivorous animals, the main food of crocodiles is fish, waterfowl, hares, deer, frogs, etc. Although hippos may look clumsy, don’t ignore their survivability. Hippo teeth are so powerful that they can pierce crocodile skin. Hippo teeth are very large. The incisors and canines are fang-shaped. The lower incisors do not grow upward but extend parallel to a shovel. The length can reach 60 to 65 centimeters and the weight is 2 to 3 kilograms. The length of the canine teeth is also about 60 centimeters. , and its hardness is so high that it can even bounce away ordinary pistol bullets.

With bullet-like teeth, it also needs to be able to shoot. The hippopotamus has a strong bite. The hippopotamus' mouth is particularly large, larger than the mouth of any animal on land, and can be opened at a 90-degree angle. As long as the hippopotamus bites the crocodile, it is not difficult to bite the crocodile. The hippopotamus has a bite force of more than 1,000 pounds per square inch, and the bite force of a female hippopotamus is 1,800 pounds or even 2,000 pounds. In addition to its offensive capabilities, the hippopotamus has the appearance of a hippopotamus. Although the crocodile is powerful, it is thin. When a fat man competes with a thin man, the fat man's tonnage is also an advantage.

The hippopotamus is a mammal second only to the African elephant, Asian elephant, African forest elephant, white rhino, and Indian rhinoceros. Its body length is 300 to 360 cm, and its tail length is about 56 cm, generally weighing between 0.9 and 1.8 tons. One disadvantage of being huge is that it is clumsy and inconvenient to move. Therefore, hippos do not appear to be aggressive and seem to have very weak combat effectiveness. The hippopotamus' body alone can overwhelm many animals in terms of momentum, making many animals afraid to provoke easily.

Another very important reason is that hippos travel in groups, and crocodiles are more like individual teams than hippos. No matter how strong a person is, when facing a group of enemies, it will always be difficult for him to defeat a group of enemies with just two fists. Teamwork can make power more concentrated, protect people in the team from being bullied by other powerful forces, and can also face crises together and resist enemies together. In fact, animals have no feelings and emotions, and most of the time they are instinctive.

Whether it is an animal or a person, you cannot judge a person by his appearance. Although sometimes you can get a lot of information through appearance, this information is often incomplete, or even It is inductive and can lead you astray. Can a strong man really be unstoppable and win in the end? In fact, it is not necessarily the case. The strong easily become the same enemy and are the first to be attacked. The weak know how to protect themselves better because they know they are weak.
