Marine biologists study life in the seas. Subjects of research include fisheries biology, marine mammals, marine plants and algae, coral reefs, deep-sea communities, zooplankton, and many more. This field is vast and growing, but it is also one of the more popular sciences. Competition for jobs can be tough and salaries are not often high.
To work in marine biology, you will eventually need an M.S. or Ph.D. College graduates who have hands-on experience in the field or laboratory tend to have an advantage when seeking entry-level work or admission to a graduate program, so try to get an internship or volunteer position during college. Marine biologists work for research institutions, universities, government agencies, television production companies, conservation groups, and more.
