The World’s Biggest Reptiles

Reptiles are vertebrates. They breath air through their lungs, laying shelled eggs and their skin is covered with scales. They are “cold blooded.”, which means their body temperature changes with the weather. Most reptiles eat meat. Reptiles are generally less clever than mammals and birds. They protect themselves through camouflage. Crocodiles, turtles, some lizards and some snakes hiss loudly when their enemies attack them. They all have 4 legs except for snakes and some lizards. They are different from from frogs because they do not have a larval stage. The world’s biggest living reptile is the Saltwater Crocodile.
