Hippos kill more people each year than lions, elephants, leopards, buffaloes and rhinos combined. The number is estimated to be around 2900 per year. Experts believe that the Hippopotamus is the most dangerous animal in all of Africa. They weigh up to 8,000 pounds and can gallop 18 mph. They also have the propensity to flip over boats for no reason and bite the passengers with their huge, sharp teeth. Hippos are aggressive, unpredictable and have no fear of humans. People die most often when they get between a hippo and deep water or between a mother and her calf.
As you can see in the video, they are super fast and very unpredictable.
