Marine Biologists

Marine biologists study the animals and plants that originate and live in the oceans. This field of marine science deals with the research on the life processes, behaviour, genetics, and diseases of living organisms that exist in the marine environment. Oceans cover 71% of the Earth’s surface and are home to a large population of all life on Earth; several species of marine life are yet to be discovered. The work of marine biologists is vital from the point of view of both pure and applied research. Marine life is significant to economy as it is a rich source of food and raw materials for several industries. Marine life includes seabirds, fishes, reptiles, invertebrates, mammals, plants, and microscopic life. Marine biologists use sophisticated satellite equipment to monitor and observe marine life and use tools like bottom trawls and plankton nets to collect samples. Specialist software is used to analyze the results of laboratory testing of these samples. The work of marine biologists also involves studying the impact of pollution, global warming, and man-made disasters like global warming on the quality of marine life. These scientists work in government organizations, marine research institutions, universities, marine rescue facilities, and commercial industries. Browse through these biographies and timelines to explore the life and works of various famous marine biologists from all over the world.
