Don't let the pudgy appearance fool you—the hippopotamus is widely considered the most dangerous large animal in Africa, killing more humans annually than lions, leopards, and crocodiles combined. Its massive jaws open to a terrifying 180-degree angle and generate 1,800 PSI of bite force through foot-long canine teeth. At 4,000 pounds, it can outrun most humans on land and is absurdly agile in water.
