What does a marine biologist do?

Marine biologists are responsible for researching the diverse organisms that inhabit the ocean in their natural environments. This can include a wide range of species, from whales and dolphins to plankton and seaweed. Their work involves studying the behavior, biology, and ecology of these marine organisms, as well as the impact of human activities on their habitats. By understanding these complex ecosystems, marine biologists play a crucial role in conservation and the sustainable management of ocean resources.
