Herpetologists study reptiles and amphibians. They conduct research on these animals, examining how they are related and how they live. Herpetologists also study environmental changes and their impacts. A career as a herpetologist typically requires a 4-year college degree and a PhD in biology, ecology, or zoology. Salaries range from $30,000 to $90,000 per year depending on the specific role and employer. Herpetologists work for universities, museums, government agencies, and other organizations.
