The scientific study of amphibians and reptiles is known as herpetology. The name comes from the Greek root herpeton which means “creeping animal.” Those who study this field of biology are known as herpetologists, though they prefer to call themselves “herpers.” Modern herpetologists specialize in a particular field of study, and it is rare to find one who focuses on general herpetology. They find work in a variety of careers, such as field research, nature guides, professors, veterinarians, museum curators, and so on. Few universities offer degrees in herpetology, so it is a highly competitive and close-knit field.
