Herpetology

Herpetology is the branch of zoology concerned with the study of reptiles (such as snakes, lizards, turtles, and crocodiles) and amphibians (such as frogs, salamanders, and caecilians). As a specialized field within biology, it encompasses the investigation of the evolution, classification, physiology, behavior, and ecology of these ectothermic ("cold-blooded") vertebrates. This discipline is critical not only for understanding the unique adaptations and life histories of these animals but also for driving conservation efforts, as many reptile and amphibian populations are currently facing significant global declines.
