Crocodile is a fierce reptile, a carnivore and the oldest reptile. At the same time as more than 200 million dinosaurs. His vitality is so tenacious that some crocodiles are now endangered wild protected animals, such as Chinese alligator, Nile crocodile, bay crocodile and so on. The crocodile's biting force is extremely strong, probably thousands of times his weight. Generally about 2000 Jin. Hippo belongs to mammals and is an omnivorous freshwater animal. It is relatively large, weighing as high as 1~2 tons, and likes to live in groups. Moreover, hippos and crocodiles often live in the same water area. Why can't crocodiles bite the hippo's skin? Next, let's talk about the reasons.

The hippopotamus's body is wrapped in its own very thick skin. The skin on the northern part of his body and on both sides of his abdomen is very thick, up to 4~5cm, and the hippo is very big, so crocodiles generally can't bite hippos, and it's not good to bite them. In fact, crocodiles dare not provoke hippos, not only because hippos have thick skin and can't bite hippos, but also because hippos' teeth are very sharp. According to research, the teeth of adult hippos can bounce off bullets fired by ordinary pistols. Because hippos can only stay underwater for about 5 minutes, they need to stick their heads out of the water. Sometimes, hippos will go back to the shore of land to bask in the sun and have a rest.

In Africa, many lions are looking for food. They saw a hippo, a lioness and a lion sunbathing on the shore. In order to find food for themselves and their children, they stared at the hippo sunbathing on the shore. Two hungry lions crept up to the hippopotamus, suddenly attacked the hippopotamus, climbed onto the back of the river and began to bite wildly. It can be seen that the hippo remained indifferent for five minutes and continued to fight with two lions. Later, the lions left in frustration and the hippo slowly returned to the water. You can see how thick the hippo's skin is.

Another main reason is that crocodiles don't bite hippos and dare not bite hippos. Hippopotamus's teeth are not only hard but also big. The two front teeth are very long, with an average of 60cm~65cm. Hippo's teeth can easily pick up crocodiles and pierce them. The biting power of hippos is also amazing. If you open your mouth, you can split the crocodile in half at once, and the average bite force is about 1500 kg, which is second only to the bite force of crocodiles, except that hippos are not carnivores. If hippos are carnivores, where there are hippos, I don't think there will be crocodiles. Hippos are also big. Its size is similar to that of elephants and rhinoceroses, and it may be slightly shorter than elephants. Their weight is generally 1~2 tons, and they are used to living in groups. Sometimes crocodiles can't get close at all. To sum up, this is why crocodiles can't bite hippos.
