What do Marine Biologist do?
Marine biologists study marine organisms in their natural habitats. They may investigate a population's behaviors or physiology. Or, they may assess the condition of habitats, and the effects of human activity on those animals and habitats.
Their research mainly includes conducting species inventories, testing and monitoring sea creatures exposed to pollutants, collecting and testing ocean samples, preserving specimens and samples of unknown species and diseases, and mapping the distribution, ranges, or movements of marine populations. In some cases, they may recommend alternative industrial practices to reduce negative effects on marine species and habitats. They may also communicate their findings and recommendations by writing reports and scientific journal articles. Some marine biologists specialize in marine biotechnology. In other words, they investigate the adaptations and advantages of marine species and how they might be applied to industrial processes. For instance, one biotech company has copied the structure of shark skin to create door knobs that germs and viruses such as MRSA (Methicillin-resistant Staphylococcus aureus) can't attach to. This is a promising and interesting area of the field.
