What is it?

What Is a Marine Biology Degree?

Marine Biology is the scientific study of ocean life, from tiny plankton to whales and coral reefs. You’ll explore how marine ecosystems function, how they’re affected by human activity, and how we can protect them for the future.


Why Study Marine Biology?

This degree is ideal if you love the ocean and want to combine scientific research with environmental action. It offers a mix of fieldwork, lab work, and data analysis - perfect for students who enjoy hands-on learning and care deeply about marine life and conservation.
