Saltwater crocodiles are the largest crocodile species and living reptiles in the world. There are an estimated 100,000 of them in the wild in the Northern Territory, where they have been ...
Alligators and crocodiles differ in some key ways, from their scales to teeth to snout shape and beyond. Watch the latest video from A-Z-Animals to discover fascinating facts about these two ...
