Reptiles are a class of cold-blooded vertebrates that include snakes, lizards, turtles, and crocodiles. They are characterized by their scaly skin, which helps prevent water loss, and most lay eggs on land. Reptiles are found in a variety of habitats, from deserts to forests, and play important roles in their ecosystems as both predators and prey. These fascinating creatures have adapted to survive in diverse environments. For instance, chameleons can change color for camouflage, while sea turtles are known for their long migrations. Understanding reptiles is crucial for conservation efforts, as many species are threatened by habitat loss and climate change.
