Why are hippopotamuses dangerous?

Hippos are so dangerous because they are highly unpredictable creatures. They are also more aggressive than any other dangerous animal that lives in Africa, more because they are not afraid of humans and often cannot be seen, especially when in murky water. A hippo's jaws are very powerful and have sharp canines and incisors that can chomp a human in half with ease. Though hippos are herbivores, that does not mean that they cannot be very aggressive and unpredictable.
