Being able to see a herd of hippopotamuses while on a safari is an absolute joy. At first look, hippos look very calm and docile yet they are the exact opposite and actually very dangerous animals.
Since hippos hibernate and sleep during the daytime in water, it is very easy to go to the river or lake and find them going about their day. However, the more you learn about hippos, the more you realize how much you need to respect them and honestly keep a very safe distance.
According to statistics about Human-Wildlife relationships, hippos kill an average of 450 to 500 people every year in Africa. These are mostly people who live near their habitat places and use the same lakes and rivers for activities such as fishing.
This alone makes the hippos more dangerous than big cat predators such as lions and leopards.
Why Are Hippos Dangerous?

If you tell someone that a hippo is the most dangerous animal in the African savannah, their next question is always "why?". Everyone would expect animals such as lions, crocodiles, and other carnivores but not the hippo.
The hippopotamus is very dangerous because of its unpredictable and volatile temper. A hippo will be calm one minute and totally dangerous the next minute. There is no formula to what agitates a hippo and what it will do with that anger.
This is why you should never be tempted to get so close to the hippos while you are on safari. The tempting selfie with yawning hippos in the background is insanely appealing but hippos don't play around.
How Do Hippos Kill Humans And Other Animals?
Hippos have one tool in their arsenal and that is their sharp incisors and canines. Whether it is a human, a crocodile, or a lion, the hippo will use its sharp teeth to crush any opponent to death in one go.
The mouth of the hippopotamus can open up to an angle of 150 degrees. The canines of a hippo can grow up to 50 cm while the incisors grow to around 40 cm.
These pairs of teeth regularly rub on each other and thus always stay sharp.
