Reptile biology is a branch of biology that focuses on the study of reptiles, which are cold-blooded vertebrates belonging to the class Reptilia. This field of research explores various aspects of reptile biology such as their anatomy, physiology, behavior, ecology, evolution, and conservation. Researchers in this field may study the diverse characteristics, adaptations, and behaviors of different reptile species, as well as their roles in ecosystems and interactions with other organisms. Understanding reptile biology is crucial for conservation efforts, as many reptile species are facing threats such as habitat loss, climate change, and poaching.
