Hippopotamuses
Many people don’t know the real power of hippos, but it is very important to understand that they can become very aggressive and attack everything that is standing in their way, from other animals to humans.
The hippo (Hippopotamus amphibius) is a large, herbivorous, semiaquatic and ungulate mammal that can be found in sub-Saharan Africa. There are two extant species in the family Hippopotamidae, namely the Hippopotamus amphibius and the pygmy hippopotamus. They are the third-largest type of land mammal and the heaviest extant artiodactyl, after the elephant and rhinos.
What is interesting about hippos is the fact that they are actually closely related to cetaceans, such as whales, dolphins, and so on. Researchers say that hippos diverged from cetaceans approx. 55 million years ago.
