JAMB Subject Combination for Marine Biology 2026/2027- Complete Guide

Marine Biology is becoming one of the most fascinating and in-demand science courses in Nigerian universities. As global attention shifts toward marine research, aquatic conservation, blue economy development, and sustainable fisheries, Marine Biology has become a valuable field for students who are passionate about the ocean, aquatic animals, and environmental sciences.

Every year, thousands of students apply for Marine Biology, but many lose their chances of admission simply because they do not know the correct JAMB subject combination, O’level requirements, or proper admission guidelines. If you’re planning to study Marine Biology in Nigeria for the 2026/2027 academic session, this comprehensive guide will explain everything you need to know.

This article covers the approved JAMB subject combination for Marine Biology, UTME and O’level requirements, Direct Entry requirements, top universities offering the course, career opportunities, admission tips, and more.

What Is Marine Biology?

Marine Biology is the scientific study of ocean life and aquatic environments. It covers all aspects of marine organisms—from small plankton to giant whales—and their interactions with the surrounding ecological, chemical, and physical ocean systems.

Students in Marine Biology learn subjects such as:

Marine Ecology
Oceanography
Fisheries Biology
Aquaculture
Marine Botany
Aquatic Pollution Studies
Environmental Biology
Marine Conservation

The field is highly research-oriented and blends Biology, Chemistry, Environmental Science, and sometimes Geography.

The Approved JAMB Subject Combination for Marine Biology

To study Marine Biology in any accredited Nigerian university, the correct JAMB subject combination is:

Biology (Compulsory)
Chemistry
Physics or Mathematics

This means you must write four subjects in JAMB:

English Language (Compulsory for all candidates)
Biology
Chemistry
Physics or Mathematics

Why These Subjects Matter

Marine Biology is a branch of biological science, so Biology is mandatory. Chemistry is needed because marine organisms and aquatic systems depend heavily on chemical interactions. Physics or Mathematics evaluates your analytical and scientific reasoning ability, which is necessary for marine research and data analysis.

WAEC, NECO, or NABTEB Requirements for Marine Biology

To be eligible for Marine Biology, you must have at least five (5) credit passes in the following O’level subjects:

Biology
English Language
Mathematics
Chemistry
Physics or Geography

Important Notes

A credit in Biology and Chemistry is compulsory.
Mathematics and English must be credited.
Physics is usually preferred, but some universities may accept Geography.
Passing Further Mathematics or Agricultural Science can give you an advantage.

A strong background in science subjects will make the course easier once you gain admission.

Direct Entry Requirements for Marine Biology

If you’re applying for Marine Biology through Direct Entry, here are the requirements:

Acceptable Qualifications

A-Level passes in Biology/Zoology and Chemistry
ND, HND, or NCE in Science Laboratory Technology, Fisheries, Environmental Science, or related fields
JUPEB/IJMB passes in relevant subjects

O’level Requirements Still Apply

You must still have the required WAEC/NECO credits even with Direct Entry.
