Reptiles are cold-blooded vertebrates characterized by scales or scutes covering their bodies. Snakes, turtles, lizards, and crocodiles are examples of reptiles. Their key feature is the ability to control body temperature through external sources, such as basking in the sun. Unlike amphibians, reptiles have impermeable skin and rely on lungs for respiration. Reproduction in reptiles varies, with some laying eggs and others giving birth to live young. Adapted to diverse environments, reptiles play crucial roles in ecosystems, often occupying terrestrial habitats.
