===Behavior===
+
While hippos may look comical and docile, they're in fact territorial and aggressive animals, known to kill more people in Africa than mammals like lions and buffalo. Males will fight each other over females and any source of water, using their front teeth to stab and inflict wounds. They share space with crocodiles, which will not attack a fully-grown hippo but may go after a calf.
