Jobs Available with a Bachelor's Degree

• A degree in biology is typically the first step in becoming a zoologist. Students take classes in physics, mathematics and chemistry, as well as biology. Classes in computer science might be required, because the zoologist might be called upon to create computer models. A four-year degree is adequate to teach at the high school level or below in most states. It opens doors as a research technician, inspector and product designer. Data from the U.S. Bureau of Labor Statistics (BLS) show that the median starting salary for recent graduates with a four-year degree in biology or life science was $33,254 annually.
  
  

Jobs Available with a Master's Degree

• Zoologists who wish to specialize in a particular animal or in fields such as microbiology should complete the requirements for a master's degree, which typically take an additional two years of study beyond the undergraduate level. Master's degrees are required by some employers for positions in applied research and management. A student can obtain a master's degree in zoology, microbiology or biochemistry. Salaries depend on the employer and the specific occupation.
  
  

Jobs Available with a Ph.D.

• A doctorate is normally required for those who wish to perform independent research, especially at the university level. Higher-level management positions normally require a doctorate as well. Teaching at the university or college level normally requires a Ph.D. also. Wildlife biologists and zoologists with a doctoral degree earned from $43,060 to $70,500 for those in the middle half of the profession, according to BLS data for 2008, while the upper 10 percent earned in excess of $90,850. Zoologists employed by the federal government had average salaries of $116,908 annually in 2009, while microbiologists received an average of $97,264 as federal employees.
  
  

Jobs Available with an Associate's Degree

• Students who obtain a two-year degree will not be able to work as zoologist. However, they might find work in a related occupation, such as a veterinary technician or a laboratory assistant, while they pursue further education.
