Reptiles inhabit a variety of environments, including forests, deserts, wetlands, and grasslands. They are often found in warm climates, as most reptiles are ectothermic, meaning they rely on external heat sources to regulate their body temperature. Common habitats include tropical rainforests, savannas, and rocky hillsides, where they can find shelter and food. Many reptiles, such as snakes and lizards, prefer areas with plenty of cover, like bushes or logs, to hide from predators. Aquatic reptiles, like turtles and alligators, thrive in water bodies such as rivers, lakes, and swamps. Each habitat provides essential resources for survival, including food, shelter, and breeding sites.
