Marine Biologists


Marine biologists study species of plants and animals living in saltwater, their interactions with one another, and how they influence and are influenced by environmental factors. Marine biology is a branch of the biological sciences, and biologists in this area work in myriad industries, including government agencies, universities, aquariums, and fish hatcheries, to name a few. They generally work either in a laboratory setting or in the field, which in this case means being in or on the ocean or its margins. Approximately 19,300 wildlife biologists and zoologists are employed in the United States.
