Crocodiles are large aquatic reptiles that live throughout the Tropics in Africa, Asia, the Americas and Australia. Crocodiles tend to congregate in freshwater habitats like rivers, lakes, wetlands and sometimes in brackish water. Some species, notably the Saltwater Crocodile of Australia, Southeast Asia and the Pacific islands often live along the coastal areas. It is also known to venture far out to sea. They mostly feed on vertebrates like fish, reptiles, and mammals, sometimes with invertebrates like mollusks and crustaceans, depending on species. They are an ancient lineage, and are believed to have changed little since the time of the dinosaurs.
