Tortoises – also known as land turtles – are reptiles that dwell on the land and are shielded from any enemies by their hard shell. They look very much akin to the sea turtles that they are related to and can be hard to tell the difference between them.
Crocodiles – which are not to be confused with alligators – are incredibly large reptiles that live in the Tropics of Asia, Africa, Australia, and the Americas. You can find most crocodiles in rivers, lakes, and wetlands. The Saltwater Crocodile of Australia, Southeast Asia and the Pacific islands often live along the coastal areas and may even swim out to sea on occasion.
