Reptilia

Reptilia, commonly known as reptiles, is a class of cold-blooded vertebrates characterized by scaly skin and the ability to lay eggs. This group includes snakes, lizards, turtles, and crocodilians. Reptiles thrive in diverse environments, from deserts to forests, and are known for their adaptations, such as camouflage and specialized diets. They breathe using lungs and have a three-chambered heart, with the exception of crocodiles, which have a four-chambered heart. Reptiles play important roles in ecosystems as predators and prey, and they have existed for millions of years, evolving alongside mammals and birds.
