The Nile Crocodile, Crocodylus niloticus, is the second largest species of reptile. It is the largest predatory animal in Africa, with males weighing in at 1100 pounds, and females weighing in at 500 pounds. These large reptiles live in almost every wet or moist terrain throughout the continent. Very aggressive, large individuals are known to scare and even attack full grown lions. It is considered the most dangerous of the crocodile species, as it is known to be an active man-eater.
