Although they might look cumbersome and cute, hippos are actually one of the most feared animals in Africa, and can outrun a human. When a male feels its territory is threatened, or a female thinks her offspring her in danger, these animals can be particularly dangerous. And with huge teeth and mouth that can open four feet wide, it's a good idea to steer clear.
Kills: An estimated 100-150 people a year.
Deadly technique: Hippos will charge, trample and gore its victims, and have been known to upturn boats and canoes without warning.
Lives in: Africa
