Lion

Even though you might already know that lions are dangerous, they’re even more dangerous than you think. Observing these animals during a safari in Africa is relatively safe, but because they’re unpredictable, it’s recommended you keep your windows closed and limbs inside the vehicle during a safari. It is especially important to be careful around predators like lions, which are adapted to hunting and killing other animals. They kill an average of 100 humans every single year (via Best Life Online).
