Herpetology is the study of reptiles, which includes snakes, lizards, turtles, and crocodiles. This field of study focuses on their biology, behavior, classification, and conservation. It involves researching their anatomy, ecology, evolutionary history, and their role in ecosystems. By studying reptiles, herpetologists aim to understand their adaptations, reproduction, and interactions with other species. They also work towards conserving reptile populations and their habitats.
