Hippos are not afraid of crocodiles in the water. On land, crocodiles are no match for hippos. Crocodiles are inconvenient to move on land. In addition to its strong bite, hippos lick crocodiles by their weight, which crocodiles can't bear. Moreover, hippos are social animals. Crocodiles that attack hippos may be attacked by hippos. A single crocodile is no match for a hippo, let alone a group fight.
Crocodiles occasionally prey on small hippos. It is still dangerous for a baby hippo to face crocodiles alone without the protection of an adult hippo. However, there are not many cases where crocodiles prey on hippos. Because the little hippo is dead, the adult hippo will be very violent and will definitely attack the crocodile crazily, so the crocodile will not take the initiative to prey on the little hippo unless it is hungry. Although crocodiles and hippos are sworn enemies in nature, in terms of food, crocodiles are carnivores and hippos are omnivores, so they generally try to avoid conflicts with each other. Unless there is a shortage of food in dry season, hippos and crocodiles will fight for water and food.
