Reptiles

Reptiles are a class of cold-blooded vertebrates that are characterized by their scaly skin, which helps to prevent water loss. They typically lay eggs, though some species give birth to live young. Reptiles include turtles, snakes, lizards, crocodilians, and the tuatara. They are primarily found in warm environments, and many species are adapted to both terrestrial and aquatic habitats. Reptiles breathe air through lungs, and their circulatory system features a three-chambered heart, although crocodilians have a more advanced four-chambered heart. They are ectothermic, meaning their body temperature is regulated by the surrounding environment, which influences their behavior and activity patterns. Reptiles play crucial roles in ecosystems as predators and prey and exhibit a wide range of adaptations for survival, including camouflage, venom, and various hunting strategies.
