Marine biology is primarily focused on the study of marine organisms, their behaviors, interactions, and ecosystems. This field explores the diversity of life forms found in oceans and coastal environments, examining not only the biological aspects but also the physical and chemical processes that govern marine habitats. Researchers in marine biology may study various topics, including the impact of human activities on marine life, the conservation of species, and the ecological roles of different organisms. Marine biologists often work to understand how climate change, pollution, and fishing practices affect oceanic ecosystems and the myriad of species that inhabit them.
