Entomology

• Entomologists are zoologists who specialize in the study of insects. In this specialty, entomologists study things such as the physiology, behavior and classification of insects, or specialize in how to control insects in the city, at farms or healthcare. Many entomologists work as researchers, teachers, consultants and government employees. Some entomologists work in the relatively new field of forensic entomology, helping solve crimes with their insect knowledge.
  
  

Ornithologists

• Ornithologists focus on birds. They study various phases of a bird's life cycle, habitation and nutrients. Some ornithologist focus on the history of birds and the influence of birds on today's environment. Ornithologists work for government agencies, nonprofit organizations or as consultants. Some zoologists specialize in ornithology part-time in addition to researching, teaching in schools or providing outdoor education for environmental education organizations such as the National Audubon Society.
  
  

Ichthyologists

• Those zoologists who choose to specialize in the study of fish are ichthyologists. The American Society of Ichthyologists and Herpetologists estimates that between 25,000 and 30,000 fish exists. These fish include species from sharks to bony fishes. Like other zoology specialties, ichthyologists study the life history, anatomy and physiology of fish. Some ichthyologists also specialize in the conservation of fish and their habitats. Ichthyologists work at aquariums, museums, universities and government agencies such as the Environmental Protection Agency (EPA).
  
  

Mammalogy

• Mammalogists study animals that have hair, a backbone and the ability to produce milk. They specialize in all aspects of a mammal's life. These zoologists also study and provide information on how to control and manage mammals. Many mammalogists work for zoos, museums, nonprofit conservation organizations and government game departments.
  
  

Other Careers

• People who earn a degree in zoology may enter careers related to the study of animals. They may work as veterinary technologists or animal caretakers. Some may choose to go into the field of wildlife or aquatic biology. Because of the study of biological sciences and physiology, zoology majors may find work in agriculture, nutrition, pharmaceuticals and public health as well.
