There are many steps in the process to become a marine biologist, and many people start at a very young age, laying the groundwork for their college educations. The first and foremost step is an interest in marine life and the oceans, as being a marine biologist would not be very enjoyable if you weren't interested in your study subjects.

Marine biologists study ocean life, ranging from huge whales to tiny planktonic organisms. They have access to some of the most interesting places in the world, including hydrothermal vents, which host bizarre organisms that use chemosynthesis for energy. The ocean is a largely unexplored territory, which means that there is a lot of work to be done in marine biology, from monitoring the populations of commercial fisheries to studying global ocean temperatures and their effect on marine life.

If you want to get a job as a marine biologist, you should start as early as possible because there's a lot of math and science to absorb. In high school, taking classes in mathematics and sciences is a big help, and if you can access marine biology courses in your school or at a local college, you should definitely consider taking them. You might also want to see if you can intern with a marine biologist, or spend a summer working in a marine biology lab, to get a sense of the hands-on work required.

For college, if you want to become a marine biologist, you should select an institution with a marine science program, and preferably you should find a school which is affiliated with a research facility. This will give you an opportunity to get real field experience, and it will allow you to work in a wide variety of facets of marine biology to see what interests you most. After you graduate with a marine biology degree, you may be able to find work in the field, but you may want to pursue graduate work to become a marine biologist with better qualifications. Additional education will expand your depth of knowledge and make you more employable.

You may find that when you become a marine biologist, a particular aspect of the field interests you, such as microscopic organisms, marine mammals, marine habitats, coral reefs, or any number of topics. Many marine biologists figure out what they want to specialize in when they intern with experienced biologists in the field, getting an idea of what the day-to-day work is like. You may, for example, find that although you are fascinated by ocean life in deep sea trenches, you don't like having to work remotely to study organisms of interest. Or that you are drawn to education, zookeeping, or a variety of other careers in marine biology.

Marine biologists work as field and lab researchers, educators, and consultants. Oil companies, militaries, and fisheries all need marine biologists to monitor their operations and provide suggestions for increased efficiency and environmentally-friendly practices. Marine biologists also work with conservation organizations, wildlife advocacy groups, zoological parks, and national governments, among others, so there is a lot of room for employment in this field.

@anon208366: That's a great idea, and it has already been discussed. To make sonar, they have to use electric currents, but it's been discovered that different sharks detect different frequencies of the sonar waves. Some sonar waves even stop the heartbeat of some sharks. Also, some sharks enjoy different sonar waves!

I'm 15 and I want to become a marine biologist. What should I specifically do at this age? In my country of Malaysia, we study maths, add-maths, biology, chemistry and physics when we're 16 in high school. I'm currently favouring deep sea ecology but I don't really know that much about marine biology, so I haven't really pinpointed which one to choose.

Does it help if I can swim and have a diving license? And is it a disadvantage if I'm afraid of sharks? I mean I do like them, but they kind of scare me. It would be nice if you'd give me some tips about this whole thing. --Iman

I would love to be a marine biologist, but at the moment, I'm 13 years and I'm starting to get bad levels in mathematics. In science I'm doing quite well, getting five a's and that's a B or A in end of year exams, so I don't really know if I'd get a place in college and university. I would like to find out a bit more about the levels you need in marine biology.

Why doesn't any one try to create a sonar sound on a surf board that would cause the sharks to know that these are people on them are not bait? even those who swim around sharks, whether in a cage or on a surf board. I believe that this could be put on or in a surf board that would save many lives, and wouldn't that be worth it all!

I would not want any recognition at all, but would love to see the safety of the sharks as well. Could this be done? please do write back I am really concerned about the lives of those loved ones who were taken, whether it was the shark's fault or not. Someone out there who is intelligent enough can do this. I believe this will work!

I have been wanting to do marine biology for quite some time now, and I am choosing my subjects next month.

I have been researching about what marine biologists do and where they work, and I have also done some other research about what subjects I would need to succeed in the future.

Unfortunately I haven't found very much, especially about what subjects I would need. I am starting to worry about making the wrong choices and taking my future backward. Is there any possibility that you could help me?

Thank you in advance. Catherine

I'm 16 and next year is the last year of my high school life. I just decided that I want to be a marine biologist. I take Biology and Maths now and also chose it for next year. Are there any more subjects needed to do marine biology in university?

I'm thinking of changing one of my subjects to either chemistry or geography because I looked up the prerequisites to my chosen university and showed that these would also help but neither did I take them this year or last year. Any more suggestions?

Wow, I have to do a career research paper for ninth grade english and this was so helpful. Right now I don't really know what I want to do in life but I think this actually convinced me to go for Marine Biology. Thank you. My life is now complete.

Seriously, thank you.

i really want to be a marine biologist and i only recently realized that this is what i want to do. when i had a talk from a man at the oceanarium. I have always been interested in wildlife and the ocean and this is something i really, really want to do. Do you have to take geography as I have already chosen my subjects and it is not possible to change.
