Marine biology is the scientific study of plants and animals that live in the ocean. Since the marine ecosystem is vast, there are many sub-fields of marine biology. A majority involve the study of specializations of certain animal groups, such as fish science and phycology, the study of algae.
Marine biology also involves studying the behavior of marine organisms in the ocean environment, adaptations living in seawater, and how they interact with each other.
Marine biology is a branch of biology and is linked to oceanography, a branch of science that studies the ocean. It also covers numerous ideas from ecology. Fields of study like physical oceanography and marine chemistry are also closely related to marine biology.
A person who specializes in marine biology is called a marine biologist. Marine biologists use various tools to study the oceans. These tools include sampling methods, such as plankton nets and bottom trawls, underwater observation using remotely operated vehicles and tracking devices, such as hydrophones.
A marine biologist’s goals can include alleviating ocean acidification, which has a potential negative effect on marine life, assisting the seafood industry in providing sustainable food to consumers or discovering new compounds that can be used to make medications.
