Hippopotamus
When we think of hippopotamus, we don’t think of them as some of the most dangerous animals in the world. But the truth of the matter is that they are. At first, they seem like happy, bumbling animals that splash in the water and keep to themselves. But in sub-Saharan Africa, these animals are considered highly dangerous, territorial, unpredictable, and aggressive. They have sharp teeth that can tear apart their prey in a matter of seconds. If you upset a hippo, you better make a run for it. They’re highly protective of their territory, and if they notice or feel any signs of encroachment, they will defend their space to death.

Their teeth are up to two feet long, and they bite with a pressure of 2,000 pounds per square inch. Furthermore, their tusks and their weight make them highly dangerous. They also weigh over 6,000 pounds, so if you happen to get stuck under one, it’s unlikely you’ll make it out alive. To add some nightmare fuel in there: hippos sweat a red liquid that makes it look like they’re sweating blood. Even though it’s not actually blood and it’s there to protect them from sunburn, the sight of it alone is enough to make people panic. And, even though mosquitos and snakes kill more humans per year than hippies, they’re still some of the most dangerous animals out there (CNTraveler).
