Crocodiles

Crocodiles are large aquatic tetrapods that live throughout the tropics in Africa, Asia, the Americas and Australia. Crocodiles are archosaurs, which means they are genetically close to birds and dinosaurs. Crocodiles tend to live in freshwater habitats such as rivers, lakes, wetlands and brackish water. They feed mostly on fish, reptiles, and mammals depending on species. They first appeared about 55 million years ago.
