What are the requirements for becoming a Marine Biologist after High School?

Scientists who research extensively about marine or saltwater species are known as marine biologists. While some marine biologists research the behaviors and habitats of marine plant life or microscopic creatures, others deal with marine animals like fish and whales. In addition to the kinds of creatures they investigate,

marine biologists have a variety of working methods. Some people carry out observational or preservational tasks in the field, while others work in research labs, combining the two.

Following several rules and standards is one of the prerequisites for studying to become a marine biologist. Being educated in marine biology requires a lot of steadfastness and commitment to not only finish the required requirements but also emerge as a professional and devoted marine biologist. A degree in this field allows one to learn about the entire marine fauna and flora. Marine biologists can work as research professionals, teachers, or administrators. 

The road to becoming a reputable marine scientist is long and arduous. To pursue a profession as a marine biologist, one must major in courses like math, physics, chemistry, and, of course, biology throughout their undergraduate studies. The most secure approach to accomplish your job ambitions is with a degree in marine biology. Additionally, technical marine biology requires high experience for reasonable compensation. 

What subjects do you need for marine biology?

To be qualified to work, a marine scientist must seek rigorous study. Any student who plans to pursue this professional route should first complete their undergraduate and graduate degrees. Students can major in biology, zoology, or marine biology as undergraduates. To become a marine biologist, one does not necessarily have to pick marine biology throughout your undergraduate studies. 

In addition to studying natural sciences, it is advised for undergraduates to take courses in engineering, mathematics, or computer science. These disciplines will significantly benefit one’s career and provide additional opportunities to apply in different contexts. 

How do I become a marine biologist after 12?

While high school courses can be a little more specialized, think about enrolling in a college that offers a famous biology degree and is close to a body of water that interests you. In light of this, be sure to participate in community cleanup initiatives around you and visit a few aquariums to broaden your understanding.

So, after completing your marine biology undergraduate degree, search for internships that will provide practical experience working in the area. These might include working at any neighborhood aquarium or river shed or conducting research on oceangoing vessels. This provides the necessary experience one needs to launch a career or give a solid foundation for graduate school. 

#1 Concentrate on Your High School Work

The path to becoming a marine biologist must be planned with the aim in mind at every stage. Potential employers generally consider specific college degrees, internships, and extracurricular activities. However, high school grades and involvement in clubs are also taken into consideration by college or university programs. Good grades and performance at high school benefit the students in their journey in marine biology. 

Thus, it is clear how one process step affects the next. Students must thus pay close attention in high school courses. This necessitates a focus on chemistry, mathematics, geology, and biology.

#2 Utilize the possibilities in the vicinity

There are several ways to develop an interest in marine biology. There are probably a few groups in town that monitor the condition of the local animals and clean up the nearby rivers. Students must actively engage in activities that lead to a better understanding of nature and specific surroundings. 

If you have your sights set on a bigger prize, consider volunteering with an ocean cleanup team. This might be anything from straightforward beach cleanups to assisting divers in cleaning up local coasts or reefs. In light of this, obtaining your diving certification is a great way to demonstrate your interest in a career as a marine scientist. This certification is the perfect way to add practical experience before becoming a marine biologist.  

#3 Selection of a University

These days, there are more universities than you can count. This may seem like a difficult endeavor while researching how to become a marine scientist. There are a couple of methods to assist you in shortening your list, though.

Be honest about your grades, SAT and ACT scores, and goals. Choose colleges that will accept your GPA and test results. You can apply to one difficult school if you like. You will be overjoyed if you succeed in getting it.

Next, check out how these schools’ biology and marine biology departments are rated. Are the instructors engaged in any research or book-writing that piques your interest? Moreover, look at the kind of experiential learning and career opportunities the university provides. You must always check the faculty members, additional courses, practical learning, and internship programs at the specified university.  

#4 Internships

Finding out how to become a marine biologist requires important internships. They allow you to collaborate directly with marine biologists, get experience, and learn more about the kind of work you want to do for a living. Internships are mandatory as they serve as a path toward your full-time career. 

The best time to add biology experience to your CV is between the academic year and the summer. Consider applying for internships focused on the water and allowing you to do real-world fieldwork. These internships add experience and lead to better connections in a similar field. Additionally, there are several labs connected to schools where you can work. 

#5 Choose a Master’s and Ph.D. Program

So, while you investigate how to become a marine biologist, you must think of adding a master’s degree. Numerous institutions offer master’s degrees in this area. It is hardly surprising that the two major centers for these degrees in the nation are Florida and California.

Master’s degrees come in a variety of specializations. You can major in conservation biology, oceanography, fisheries, and ocean science. You can also choose to major in zoology, tropical conservation biology, estuary science, vertebrate biology, or even aquatic resources. Considering a particular area for majors is dependent on your interest levels. 

You will be prepared for your profession differently through each of these programs. Post masters, you can consider opting for Ph.D. programs in Marine Biology that help expand your knowledge and expertise in the subject matter. Similar to when applying to a four-year university, take into account the institution’s faculty, publications, and other output. 


Just like any other profession, being a marine biologist requires certain requirements which must be met. Hence, to give you a clearer picture, here are a few pre-requisites you absolutely need before heading on to the road to become a Marine Biologist. 

#1 High School

You need to complete high school before enrolling in institutions with reputable Marine Biology Programs. It would be great to attend a place where undergraduates are permitted to make important research contributions; therefore, don’t disregard tiny institutions. Choosing an institution that focuses on an experiential learning environment is important. 

#2 Undergraduate

You would need to first earn a biology undergraduate degree, preferably in marine biology. Get as much marine biology research experience as possible while obtaining this undergraduate degree. The study should not directly connect to your areas of interest as long as it demonstrates your enthusiasm for marine biology and your capacity to advance the discipline.

#3 Graduate study
