A reptile refers to a cold-blooded vertebrate animal belonging to the class Reptilia, which includes creatures like reptiles, lizards, turtles, and crocodiles. Reptiles are characterized by various distinct features, such as scaly skin that provides protection and helps reduce water loss, as well as the ability to lay or fertilize eggs on land.
Reptiles are primarily found in almost every habitat across the globe except for extremely cold regions. They can be aquatic, terrestrial, or arboreal, making their homes in diverse environments like deserts, forests, grasslands, and even underground. Reptiles are notable for their adaptability and have evolved various mechanisms to withstand environmental conditions like extreme heat or limited water sources.
These creatures have a unique exothermic metabolism, meaning their internal body temperature is regulated by external heat sources. Because they are cold-blooded, reptiles are reliant on their environment to thermoregulate and maintain their bodily functions. They have a well-developed muscular system and exhibit a wide range of locomotion methods, including crawling, walking, burrowing, and swimming.
While most reptiles lay eggs, some species give birth to live young. They typically reproduce sexually, with internal fertilization occurring in various ways across different reptilian groups. Many reptiles are carnivorous, consuming a diet consisting of insects, small mammals, fish, birds, and other reptiles. However, some reptiles have adapted to herbivory, feeding on plants, fruits, and vegetation.
Reptiles have existed on Earth for millions of years and have played vital ecological roles as both predators and prey. They have captured the fascination of humans through their unique characteristics, diverse species, and appearances, making them subjects of scientific study, conservation efforts, and
