Marine Biology Concentration

Biology, B.S.


Earn a Biology, B.S. with a Concentration in Marine Biology at Saint Francis University. 

Marine biologists study many aspects of marine life from plankton to whales and tropical corals to deep-sea crabs. They investigate these animals from the molecular level through the entire ecosystem. They study the effects of human activity on oceans and develop conservation plans to protect marine life. Biology majors at SFU who have a passion to study the oceans' biodiversity can pursue a Marine Biology Concentration as part of their degree path.

study abroad and gain hands-on experience in marine biology
earn a Biological Diving Minor to expand your skills

pursue a challenging career in marine research, conservation, resource management, or marine policy

Experience a hands-on education in marine biology!


Take hands-on courses in marine biology, oceanography, invertebrate zoology, aquarium maintenance, field biology, and unique scuba diving courses such as coral reef ecology and research diver methods.  Plus engage firsthand with oceanic ecosystems through class trips working alongside marine biology faculty.


The Marine Biology Concentration

(B.S. in Biology)

Broadly explore marine biology in your first two years and then spend the last two years preparing for careers as field biologists, coral reef ecologists, fisheries biologists, aquaculturists, etc., or getting ready for graduate school.

Plan of Study  / Course Catalog


Many students in the Marine Biology concentration add on additional specialization through a Biological Diving minor,  a second concentration in Ecology & Environmental Biology, or double majoring in Biology and Aquarium and Zoo Sciences.




Marine Biology the Saint Francis Way

The oceans cover 71% of the world (and rising)! Scientists estimate that less than 5% of the oceans have been explored. Nevertheless, scientific exploration of our planet's oceans has revealed incredible marine biodiversity, along with a better understanding of the processes by which oceans shape global weather, food supplies, and economies.  Our students explore these ecosystems and learn how climate change and other human activities threaten to permanently alter these fragile systems--and what we can do to help.

Marine-Related Student Opportunities 


SCUBA: Students learn to scuba dive or continue to build diving skills while exploring the fascinating underwater world. Courses in SCUBA are offered in both fall and spring semesters. including groups trips to the Caribean each spring.  Activities are sponsored by the Scuba Club throughout the year to keep divers actively involved in the sport.  Students taking SCUBA courses can earn a Biological Diving Minor.


Field Biology Course: The BIOL 322 Field Biology course has allowed students to study biological systems around the world, including Australia, the Galapagos, and Belize.  Students prepare with readings and assignments throughout the semester, and then travel to destinations either during spring break or immediately following spring semester.

Biological Diving Minor


  • This minor is highly recommended for Marine Biology students as well as Aquarium and Zoo Science students but is open to all majors.
  • Combine your training in marine science and field biology with advanced study in SCUBA techniques. 
  • Learn to scuba dive by completing lectures, pool sessions, and open water training dives.
  • Upon completion receive internationally-recognized certifications from  Professional Association of Diving Instructors (PADI) 

Career Outlook in Marine Biology

The Marine Biology Concentration prepares students for careers as field biologists, coral reef ecologists, fisheries biologists, aquaculturists, etc., or to continue their studies in graduate-level programs.  Marine Biologists find career opportunities in state and federal government agencies, private research laboratories, aquaria, zoos, museums, and academia.


US Bureau of Labor Statistics outlook for life, physical, and social science occupations:

The US BLS projects stable growth in life, physical, and social science occupations through 2030. Increasing demand for expertise in the sciences, particularly in occupations involved in biomedical research, psychology, and environmental protection, is projected to result in employment growth. The median annual wage for life, physical, and social science occupations was $69,760 in May 2020, which was higher than the median wage for all occupations of $41,950.
