A biologist is a scientist who studies living organisms. Biologists involved in basic research attempt to discover underlying mechanisms that govern how organisms function. Biologists involved in applied research attempt to develop or improve medical, industrial or agricultural processes. Some biologists work in management positions coordinating or supervising research.
Marine biologists study organisms that live in an ocean or sea environment. Much of their time is spent in the field collecting data about plant and animal species. This data is then analyzed in a lab or an office to advance the understanding of species and their environments. There are many areas of specialization in marine biology, ranging from animal behavior to marine biotechnology. Some marine biologists focus on a particular species or geographic region. Whatever their specialty, marine biologists must have knowledge in biology, chemistry, physics, geology, and ecology.
