The specie breeds on the land, swim and feed in water because of their ability to survive the water world an advantage that comes because of their lizard like form. This specie provides benefit for the ecosystem for humans while still advancing their own individual survival needs, reproduction and maintenance (Sohlberg, 2001). Crocodiles serve as apex predators ecologically but keep prey populations in check. The larger crocodiles tend to be very dangerous to human beings but provide nutritional, commercial and aesthetic benefit. Traders mostly use their tanned hides to make leather goods and in many parts of the world, crocodile meat is considered a delicacy.
