Career guide

Marine Biologist

Investigative

Studies life in the sea and coastal systems. Far less diving and far more data, boats and laboratory work than most learners expect.

This career needs Core Mathematics.
Mathematical Literacy is not accepted for it at South African universities. This choice is made in Grade 9, for Grade 10 — and it is very difficult to reverse later. If this career is on your list, take Core Mathematics.

School subjects

Mathematics (NOT Mathematical Literacy) and Life Sciences are required; Physical Sciences is required or strongly preferred by most faculties.

How you qualify

BSc, 3 years, majoring in the relevant discipline, then BSc Honours, 1 year, which is the usual minimum for professional work and for registration with SACNASP as a Professional Natural Scientist. Many research and specialist posts expect a Master's. You may register as a Candidate Natural Scientist straight after qualifying, with no experience required. Entry requirements and APS differ by institution and change yearly - confirm directly with the institution.

Where to study

Public universities; registration with SACNASP required to practise as a professional natural scientist

Before you decide. Entry requirements change every year and differ between institutions. We do not publish admission point scores here, because a number that is right for one university in one year is wrong for another. Confirm the requirements directly with the institution before your subject selection form is signed. In KwaZulu-Natal, applications go through the Central Applications Office (cao.ac.za).
