Reptiles are a class of cold-blooded vertebrates that belong to the order Reptilia. They are characterized by their scaly skin, which is waterproof and prevents dehydration, allowing them to thrive in various terrestrial habitats. Reptiles exhibit a diversified morphology and size, ranging from tiny lizards to large crocodilians. Unlike mammals, they lay eggs with leathery shells, but some species give birth to live young.
Ecologically, reptiles play crucial roles in their ecosystems as predators, prey, and scavengers. They contribute to the balance of food webs by controlling pest populations and serve as indicators of environmental health. Many reptiles are also essential for pollination and seed dispersal, thus aiding in plant reproduction and ecosystem stability.
