Marine biology is the scientific study of living organisms in the ocean or other marine or brackish bodies of water. Marine biology is the perfect career choice for budding underwater explorers—those who are fascinated by ocean creatures like sharks, crabs, fish, and coral. Marine biologists are scientists who study saltwater organisms and their relationships to their environments. The specific subject areas that marine biologists can focus on are almost limitless. For example, some might research the migration of ocean seals, while others might investigate the interaction between sea anemones and coral in a certain area. Some study the population fluctuations in different species of fish. Biologists may also look at the complex chemical makeup of marine toxins, both natural (in poisonous sea creatures) and man-made. Some study the effects of weather and environmental changes on the oceans and their marine life, and try to develop solutions to the problems they find. One large area of concern is climate change and the effect it will have on the ocean ecosystem. Marine biologists do both independent research and teamwork with other professionals. A marine biologist may work with engineers, business managers, technicians, and scientists from other disciplines..
