3. Hippopotamus (1,825 psi)
The hippopotamus is widely considered to be the No. 1 most dangerous animal in Africa, which certainly puts it in the running for most dangerous animal in the world. They may look like goofy, awkward oafs, but make no mistake: nearly everything about the hippopotamus is deadly. Enormous at 4,000 pounds (that’s two tons), hippos are among the largest mammals. They are aggressive and, despite appearances, they are relatively fast and able to reach speeds up to 30 miles per hour. And those huge maws! Their mouths are filled with teeth that can reach nearly 2 feet in length, backed by the most powerful bite of any land mammal. And despite the species’ meatless diet, it takes little provocation for a hippo to attack a human. More hippos kill people in Africa than any other animal. A recent theory even posits that King Tut was killed by one. Taming them won’t work either. In South Africa, a farmer named Marius Els raised a pet hippo, Humphrey, from the animal’s infancy. “Humphrey's like a son to me,” Els said. However, Humphrey bit and killed Els last year. In short, a hippo’s bite = death.
