Career in Marine Biology in India: Admission, Courses, Eligibility, Job, Salary etc.

Career in Marine biology: Marine Biology is the science that deals with animals and plants that live in the sea. It also deals with airborne and terrestrial organisms that depend directly upon bodies of salt water for food and other necessities of life. In the broadest sense, it attempts to describe all vital phenomena of the throng of living things that dwell in the world’s vast oceans. Marine biology is closely related to the science of oceanography as the relationship between the physical features of the oceans to the living organisms that dwell in them. It aids in understanding marine geology through studying those organisms that contribute their skeletal remains to the floors of the oceans or that elaborate the vast coral reefs of the tropic seas.

What is Marine Biology?

Marine Biology is a scientific discipline that deals with all types of sea creatures or marine bodies of water. It studies various life forms in the ocean and their behaviour and interactions with each other and the environment. Marine Biology consists of various sub-disciplines.

A principal aim of marine biology is to discover how ocean phenomena control the distribution of organisms. Marine biologists study how particular organisms are adapted to the seawater’s various chemical and physical properties of the seawater, the movements and currents of the ocean, the availability of light at various depths, and the solid surfaces that make up the seafloor. Special attention is given to determining the dynamics of marine ecosystems, particularly to understanding food chains and predator-prey relationships.

Some marine Biologists may work on algae and other microorganisms, while others may concentrate on large animals like fish. Marine Biologists study core subjects like Physics, Biology, Chemistry, Ecology, Mathematics, Geology, and Anthropology and apply this knowledge to studying oceans and ocean life forms.

Who is a Marine Biologist?

A person who specialises in Marine Biology and pursues Marine Biology Courses is commonly known as Marine Biologist. Sometimes a Marine Biologist can be referred to as Marine Scientist, Marine Life Biologist, and Ocean Biologist.

They are trained professionals to examine various sea creatures and can continue their studies by specialising in a large ocean animal or a microscopic sea organism. A Marine Scientist’s works are more cornered around researching, and field works rather than simply sitting on a bench and doing the studies.

  1. Sir / Mam ..
    I have completed bachelor’s degree in commerce, but it is not what I need.
    I like marine biology what should I do to find the required details.

    • The minimum required percentile in the merit-based or entrance exam should be 55% – 60%. Applying to a master’s program, one must hold a degree in the same field like BSc in Marine Biology, zoology, botany, biochemistry, microbiology, biotechnology, fisheries, or aquaculture.


    • You should go ahead with your core subject; Post Graduation from a subject related to zoology make your professional career easier in many ways. MBA is also a good option but makes sure specialization must be related to biology.
