Zoology is the scientific study of animals, including their behavior, physiology, classification, and habitats. A zoologist conducts research by observing animal behavior in the field or lab, studying genetics and disease, and analyzing findings to learn about animal origins and traits. Zoologists typically work in colleges, universities, zoos, aquariums, or for state and local agencies, and require at least a bachelor's degree in zoology, though many earn a master's or PhD for research roles. Physical demands can include sitting, attention to detail, lifting, and activity in the field. Salaries range from $31,000 for bachelors to over $71,000 for doctoral positions.
