Marine biology is the study of any living plant or animal in the sea. Marine biologists study it. Like other scientists, marine biologists must know a lot about the creatures they are studying. They also must understand how the sea works. The study of how the sea works is oceanography.
A marine biologist needs a bachelor's degree in biology, followed by at least an MSc in marine biology.
The ocean is large and marine biologists work in many subfields like invertebrate zoology, ichthyology, and physiology. Others study physical traits like scales, eyes, or shells.
