What do alligators eat in Africa?

There are no alligators in Africa, just crocodiles. The Nile crocodile is the largest of the African species (and the second largest of all croc species) and adult Nile crocodiles feed on a variety of animals including fish, ungulates, bovids, and primates (including humans.) Crocodiles and other large predators generally avoid each-other due to the chance of mortal injury, although on rare occasions adult Nile crocodiles have been observed taking lions and leopards.
