Crocodiles were large, amphibious reptiles.
Carnivorous, water-dwelling reptiles, crocodiles lived in several countries worldwide, most notably in Egypt, where they hunted in rivers and lakes for fish, birds and larger prey, including humans. Crocodiles could reach lengths of up to thirty feet and were sometimes hunted for their leathery skin as well as their meat. The ancient Egyptians worshipped the crocodile as a symbol of the Nile River, in the form of a crocodile-headed man named Sobek. Alex O'Connell had encountered several crocodiles when he had fallen into the Nile River from a riverboat and had almost been taken by them. Crocodiles also resided in the Blue Nile river, which led out of Egypt and into Abyssinia.
