17. Cape buffalo

Cape buffalo, also known as “The Black Death” and “widowmaker,” are notoriously dangerous among hunters in Africa. When wounded, they’ll run off and then sometimes circle back to attack the hunter who shot them. It’s almost like they were upset about getting shot, but that’s just a wild guess.

There are some estimates that say Cape buffalo kill about 200 people a year. And despite the fact that they’re herbivores, their killing isn’t limited to humans. When lions attack them, Cape buffalo will sometimes fight back and kill the lion instead. It’s pretty brutal, because in the process the buffalo will fling a lion up in the air.
