A herpetologist is a biologist who specializes in the study of reptiles and amphibians, including their behavior, ecology, physiology, and conservation. This field of study encompasses a wide range of species, from snakes and lizards to frogs and salamanders. Herpetologists often conduct research in the field and laboratory, contributing to our understanding of biodiversity and the ecological roles of these animals. Their work is crucial for the conservation of threatened species and habitats.
