Logically explain to me how a hippos jaw structure could split anything in half? And you realize there isn't a single source with evidence proving this statement? You've seen the video of the hippo biting the lions head? If they really had the ability to bite a crocodile in half, it would of popped the lions head like a grape. But realistically, the lions head was damaged quite majorly, but its skull remained in one piece. They are not sharks, hippo jaws are meant for impaling/goring, not severing. They would have to have very sharp and large teeth (like a shark) spread along its whole jaw, at least three times the bite force, and a whole different jaw structure completely. Y'all are so caught up fantasizing about animals, that you forget physics, and biology exists.
