What is a Marine Biologist?

Aug 11, 2023 | Education

Marine biologists, the guardians of oceanic ecosystems, engage in a diverse array of responsibilities that extend beyond traditional scientific roles. The Australian Government defines marine biology as “To study the anatomy, physiology, functions, characteristics, behaviour and environments of all forms of life living in the sea and connected water bodies.”

While AMFA do not provide a marine biology course, our range of great courses can serve as a great introduction to the industry! In this article, we will delve into the field of marine biology.

Scientific Detectives of the Ocean

At the heart of a marine biologist’s work lies the spirit of scientific inquiry. Armed with curiosity and a dedication to unraveling nature’s secrets, these professionals conduct experiments that provide a window into the natural systems of the ocean. From studying the behavior of marine organisms to investigating the effects of environmental changes, marine biologists act as detectives, piecing together the puzzle of life beneath the waves [1].

Caretakers of Sea Creatures

Beyond the sterile environment of a laboratory, marine biologists are hands-on caretakers of marine life. Their duties extend to caring for sick and injured sea creatures, ensuring their well-being in the ever-changing underwater landscape. The everyday functions of marine life are meticulously monitored, emphasizing the role of marine biologists as stewards of these vital species [2].

Monitoring, Testing, and Developing Theories

Marine biologists play a pivotal role in safeguarding the health of marine life. They conduct inventories, testing, and monitoring of marine organisms exposed to pollutants, collecting samples and data that become the building blocks for innovative theories. This hands-on approach to research is instrumental in understanding the impact of human activities on marine ecosystems and developing strategies for conservation [3][4].

Knowledge Dissemination and Advocacy

Communication is a cornerstone of a marine biologist’s work. Their groundbreaking findings are presented not only in scientific journals but also through reports and conferences. This dissemination of knowledge contributes not only to the scientific community but also informs government decisions related to marine conservation. Marine biologists, therefore, become advocates for the fragile ecosystems they study, translating their discoveries into actionable insights for policymakers [6].

Planning and Managing Surveys for Environmental Insight

The role of a marine biologist extends to planning and managing surveys that provide crucial insights into marine environments. With a specific focus on marine fish and fish habitats, these surveys contribute to a deeper understanding of the delicate balance within ocean ecosystems. By managing these surveys, marine biologists become active contributors to environmental stewardship [5].

Do AMFA have an Marine Biology course?

At AMFA, we offer a diverse array of courses that cater to different aspects of the maritime industry. We do not offer an “marine biology” course per se, but rather our courses may help you get a job in the industry. Check out our Flexible Industry Pathways course!


In essence, marine biologists are not just scientists; they are guardians of the ocean. Their multifaceted roles, from scientific inquiry to environmental advocacy, showcase the breadth of their impact on our understanding and conservation of marine life. As we continue to explore and exploit the vastness of the oceans, marine biologists stand as sentinels, working tirelessly to ensure the sustainability and health of these vital ecosystems.
