Marine Biology is the study of living organisms found in oceans, seas and other marine environments.
The course focuses on marine organisms and the environments in which they live. Students may encounter areas connected with aquatic ecosystems, marine biodiversity, fish biology, ecology and the relationships between organisms and their surroundings.
Marine Biology also involves practical scientific study, including laboratory work and field observations connected with aquatic and coastal environments.
It is closely related to programmes such as Fisheries and Aquaculture, Oceanography, Marine Biology and Fisheries, Environmental Biology and Zoology, but these courses should not automatically be treated as having the same admission requirements.
This guide explains the JAMB subject combination for Marine Biology for the 2027/2028 admission session, together with the O’Level, Direct Entry and university-specific requirements candidates should know.

JAMB Subject Combination for Marine Biology 2027/2028
The general JAMB UTME subject combination for Marine Biology is:
| Subject | Requirement |
|---|---|
| English Language | Compulsory |
| Biology | Required |
| Chemistry | Required |
| Physics or Mathematics | Required |
Your four UTME subjects should therefore be:
English Language, Biology, Chemistry, and either Physics or Mathematics.
Biology and Chemistry are the main science subjects in the combination, while the fourth subject may generally be Physics or Mathematics.
However, candidates should not assume that both options are accepted by every university.
For example, the University of Lagos specifically requires Biology, Chemistry and Physics for Marine Biology.
This means candidates targeting a university with a stricter requirement should follow that institution’s exact combination rather than relying only on the general subject combination.
O’Level Requirements for Marine Biology
The general O’Level requirement for Marine Biology is five SSC credit passes in the following subjects:
- English Language
- Mathematics
- Biology
- Chemistry
- One other Science subject
A simple breakdown is shown below:
| O’Level Subject | Requirement |
|---|---|
| English Language | Credit required |
| Mathematics | Credit required |
| Biology | Credit required |
| Chemistry | Credit required |
| One other Science subject | Credit required |
The additional Science subject may vary depending on the university.
For example, the University of Lagos specifically requires Physics, which means candidates applying there need credits in:
English Language, Mathematics, Biology, Chemistry and Physics.
Because Marine Biology is a science-based course, candidates should make sure their O’Level subjects provide a strong foundation in Biology and Chemistry, together with the other required science subjects.
University-specific requirements should be checked carefully, especially where Physics is specifically required instead of a broader Science-subject option.
Direct Entry Requirements for Marine Biology
The general Direct Entry requirement for Marine Biology is:
- Two A’Level passes in Biology and Chemistry.
Candidates applying through Direct Entry should also meet the required O’Level conditions for the programme.
A simple summary is shown below:
| Qualification | General Requirement |
|---|---|
| A’Level | Biology and Chemistry |
| JUPEB | Relevant science subjects where accepted |
| ND | Relevant programme where accepted |
| HND | Relevant programme where accepted |
| NCE | Relevant science qualification where accepted |
Some universities may apply more specific conditions.
For example:
- University of Lagos accepts very good JUPEB or A’Level passes in Biology, Chemistry and Physics.
- Candidates applying through other related programme titles such as Marine Biology and Fisheries may face different Direct Entry conditions from those applying for Marine Biology itself.
- Some institutions offering related courses may also consider qualifications such as NCE, ND or HND in relevant science or aquatic programmes.
Direct Entry candidates should therefore check the exact Marine Biology programme offered by their chosen university and confirm the accepted qualification, subject combination and minimum grade before applying.

- JAMB Subject Combination for Botany 2027/2028
- JAMB Subject Combination for Biochemistry 2027/2028
These programmes may overlap in some areas, but they are not the same course.
For example, Fisheries and Aquaculture places more emphasis on fish production, aquatic resource management and related activities, while Oceanography studies the ocean more broadly.
Candidates should therefore use the admission requirements attached to the exact programme title offered by their chosen university.
Core Focus Areas in Marine Biology
Marine Biology focuses on living organisms found in marine environments and the ecosystems that support them.
Important areas include:
- Marine Ecology: Studying how marine organisms interact with each other and with their environment.
- Marine Organisms: Examining animals, plants and microorganisms that live in seas, oceans and coastal waters.
- Aquatic Ecosystems: Understanding biological communities found in marine and other aquatic environments.
- Marine Biodiversity: Studying the variety of organisms found in marine habitats and their ecological importance.
- Fish Biology: Examining the structure, growth, reproduction and behaviour of fish species.
- Coastal Environments: Studying ecosystems found around shorelines, estuaries and other coastal areas.
- Marine Conservation: Understanding the protection and sustainable management of marine organisms and habitats.
- Laboratory and Field Studies: Developing practical skills through the observation, identification and study of marine organisms and aquatic environments.
How Marine Biology Differs from Oceanography
Marine Biology focuses mainly on living organisms in marine environments and the biological relationships within those ecosystems.
Oceanography studies the ocean more broadly and may include its physical, chemical, geological and biological characteristics.
This means a Marine Biology student is generally more focused on marine life and ecosystems, while an Oceanography programme may examine the ocean as a complete environmental system.
Candidates should still check the structure of the programme offered by their preferred university because course content can vary between institutions.
Typical Career Paths
Marine Biology can lead to opportunities in research, environmental management, conservation, fisheries and other aquatic science fields.
Possible career directions include:
- Marine Biological Research: Studying marine organisms, their behaviour, reproduction, distribution and relationships within aquatic ecosystems.
- Fisheries Research: Supporting studies involving fish populations, aquatic resources and the sustainable use of fisheries.
- Marine Conservation: Working on the protection of marine species, habitats and biodiversity.
- Environmental Monitoring: Examining water quality, marine habitats and environmental changes that may affect aquatic organisms.
- Aquatic and Marine Laboratories: Carrying out laboratory investigations involving water samples, marine organisms and other biological materials.
- Coastal Resource Management: Supporting the study and sustainable management of coastal ecosystems, estuaries and other marine environments.
- Aquaculture-Related Research: Contributing to scientific work involving fish and other aquatic organisms raised under controlled conditions.
- Academic and Research Institutions: Progressing to postgraduate study and working in universities, research centres or other scientific organisations.
Important Things to Know Before Choosing Marine Biology in JAMB
Marine Biology is a specialised biological science course, so candidates should understand both its admission requirements and the type of study involved.
Keep these points in mind:
- Biology and Chemistry are core UTME subjects. Both form part of the general Marine Biology combination.
- The fourth UTME subject may generally be Physics or Mathematics. However, individual universities may set a stricter requirement.
- Some universities specifically require Physics. The University of Lagos, for example, requires Biology, Chemistry and Physics for UTME.
- Mathematics is required at O’Level. Candidates generally need a credit in Mathematics alongside English Language, Biology and Chemistry.
- The fifth O’Level Science subject may depend on the university. While the general requirement allows another Science subject, some institutions specifically require Physics.
- Programme titles matter. Marine Biology, Marine Biology and Fisheries, Fisheries and Aquaculture, Oceanography and Marine Science should not automatically be treated as having identical admission requirements.
- The course may involve fieldwork. Students can expect practical study connected with aquatic environments, coastal areas, marine organisms and laboratory analysis.
- Direct Entry conditions may be more specific. Candidates should check the exact A’Level, JUPEB or other qualification accepted by the university offering Marine Biology.
Before applying, candidates should compare their UTME subjects and O’Level results with the exact Marine Biology requirement of their chosen university.
