Learn About a Being Marine Biologist

By | May 15, 2024

What Does a Marine Biologist Do? – Marines are drafted into the military to fight in wars. They often have to put their lives on the line, and there’s little guaranteed health insurance for them once they leave the service. This is where marine biologist comes in. Marine biologists are used to studying and monitoring marine life in remote areas, so they can better understand how these creatures interact with each other and their environment. They also use their knowledge of marine ecology to help warfare efforts.

Marine biologists are responsible for studying marine life and its environment on land, in the water, and in space. They use their knowledge to protect our coasts, waters, fisheries, and climate. In addition to their work in marine biology, biologists also study other disciplines such as ecology and paleontology.


What does a marine biologist do?

A marine biologist is someone who researches and studies the ocean. They work in many different fields, but marine biologists are especially interested in studying the ocean’s climate, its fishes, and marine mammals. Marine biologists study the sea floor and its history, as well as how it helps to support life on land.

A marine biologist is someone who studies marine life-forms and their place in the ocean environment. This can include marine animals as different as fish and whales, as well as plants like kelp and seagrass, or even algae, coral and microorganisms. Marine biologists undergo years of education so they can thoroughly research marine life and report on their findings.

Once you complete your educational requirements, you can work in several different settings. The most popular employer for marine biologists is the government, with jobs available in many states or through the Department of the Interior. You may also find work at places like aquariums, private research facilities or universities.


As a marine biologist, you’ll likely work full-time, both in the field and at an office. You’ll spend this time observing and researching your specific interest in marine biology.

How to become a marine biologist

Here are some important steps to take if you’d like to pursue a career in marine biology:

1. Earn a bachelor’s degree

Getting a bachelor’s degree will allow you to get an entry-level position within marine biology. For your degree, you can either enter into a program specifically for marine biology or a related program, such as zoology.

During your undergraduate degree program, you will learn generally about marine biology and gain hands-on experience. Most bachelor’s degree programs require you to take practical laboratory classes, apply for internships and seek research opportunities. Through these, you will learn more about the profession and gain some guided experience.

Once you receive your bachelor’s degree in marine biology, you’re ready to perform entry-level jobs as a marine biologist, such as a biological laboratory technician or a research assistant for a private company to help them develop products. However, if you want to do more advanced work, you will need to continue your education.

2. Earn a master’s degree

A master’s degree is the next step in continuing your education to become a marine biologist. In addition to studying marine biology, you can also study similar subjects such as marine conservation or biological oceanography. You should consider what you specifically want to study in your career and choose a master’s program that aligns with those goals.

A typical master’s degree takes around two years to complete, but in some cases, you can do it in as little as 15 months. During your studies, you may have the opportunity to begin specializing on a specific organism, species or ecosystem. As a part of your master’s program, you will conduct extensive research and also perform hands-on learning in your area of focus.

After you receive your master’s degree, some jobs available to you include environmental scientist, zoologist or natural science manager.

3. Receive your doctorate

Many marine biologists would like to conduct their research and teach at a university. If this is one of your goals, then you will need to get your doctoral degree. Some schools offer marine biology doctoral programs, but you can also pursue a doctorate in a related subject like oceanography.

A doctorate requires extensive study and a final dissertation. Exams are a regular part of your doctorate program, just like they were for attaining your bachelor’s and master’s degrees. You can expect to spend at least three years within a doctoral program, or possibly even up to five years.

4. Additional training

Broadly speaking, formal training isn’t required to become a marine biologist. However, for some jobs, you will need additional training. For example, if you want to work out on the ocean, you may need training on how to operate a boat or how to handle the technical equipment on board.

Marine biologists can receive this additional training in a few ways. You could take an internship, both during your studies and after. You could also work on research projects with established marine biologists who can provide training for you. Finally, there are volunteer opportunities available where you can gain valuable skills.

5. Choose your career path

Your career path depends on where your interests lie and how much education you have pursued. You should consider what areas of marine biology interest you the most, then explore the opportunities available within that specialty.

For example, if you would like to work with dolphins, then you likely only need a bachelor’s degree to get a job as a dolphin trainer at a zoo or aquarium. But if you want to study the effects of climate change on dolphin habitats and behaviors, you will need a doctorate to acquire funding to conduct your own research.

Frequently asked questions

Here are some common questions about the marine biologist profession:

How much do marine biologists make?

The average salary for a marine biologist is $43,916 per year. Salaries in the field range greatly — between $20,637 and $88,243 per year. The amount you can earn will depend on your location, the field you wish to study and your education level. For the most up-to-date salary information from Indeed, click on the link provided.

Do marine biologists need special certifications or licenses?

There are no special certifications you need to become a marine biologist. However, since many work out on the open ocean, it’s recommended that you get open water diving certified, which is a step beyond scuba certification.

Another thing to consider, if you want to work out on the ocean, is that you may need training on how to operate a boat and how to handle the technical equipment that comes on board. An operator’s license may be required.

What kind of courses should I focus on in high school and college?

Some beneficial topics you can focus on during high school and your undergraduate years are science and math classes. You should aim to keep your knowledge base broad to help you figure out if marine biology is the right career for you. Graduate schools often favor candidates with a strong educational foundation in many subjects.

How should I choose which schools to attend for marine biology?

There are many schools that offer programs in marine biology. The best thing you can do is consider all the relevant factors before making a decision. Research the programs offered, look at the coursework you’ll be studying, analyze the cost of the program, and see if it’s close to where you want to live.

A lot more goes into picking a school than just the programs available, so be sure you’re considering all the factors before making a decision.

Are there any organizations for marine biology?

Yes, there are a number of organizations that marine biologists can join, including:

  • American Association for the Advancement of Science

  • American Fisheries Society

  • Association for the Sciences of Limnology and Oceanography
