A marine biologist is someone who works in some branch of marine biology. Given that around 70 percent of the Earth's surface is covered in oceans, you can imagine that marine biology is a very large field, encompassing everything from studies of ocean currents to analysis of the creatures who live next to hydrothermal vents. As a general rule, a person in this position is passionate about and interested in some aspect of the ocean, and he or she usually works to study and preserve ocean life while also educating people about it.

Marine biology itself is usually defined as a study of the marine ecosystem, which includes the world's oceans and some brackish regions such as estuaries. The animal and plant life in the ocean is incredibly diverse, ranging from single celled organisms like diatoms to massive blue whales. Because marine biology is such a varied field of study, a marine biologist typically picks a single aspect to focus on. For example, he or she might specialize in fisheries conservation, or rehabilitation of injured marine mammals.

One thing marine biologists don't do is handle marine mammals. Zoologists more typically work with whales and dolphins, and people who are interested in careers with these animals should pursue zoology, rather than marine biology. But a marine biologist studies lots of other interesting things, like the potential for pharmaceutical products derived from the ocean, or ways in which human activities impact the ocean.

Pay for a marine biologist can sometimes be less than ideal, but many people in the profession feel that the flexibility of the field makes up for this shortcoming. Many people in this field get to travel to interesting places and work with cutting edge equipment, sometimes with a high level of autonomy along with staff assistants. Others may focus on studies in labs, with the hope of learning more about specific ocean organisms and their interactions with one another, while some work in the field of education.

The possible careers for a marine biologist are myriad, and are suitable for people with a wide range of abilities and interests, as long as they are passionate and committed. If you are interested in becoming a marine biologist, you should focus on science as early in your education as possible, and you should try to go to college at an institution with marine biology research facilities. You might also consider pursuing internships and other opportunities for experience in the field, to see if marine biology is the right career for you.

I want to become a marine biologist but I don't live close to the ocean. (I live in Switzerland.) Is it a problem? Could I still become a marine biologist?

By anon345804 — On Aug 22, 2013

Marine biologists help all kinds of animals in the water and the ones at Sea World too. They help the populations grow and help them live also if they are injured or sick.

By anon313284 — On Jan 11, 2013

All these kids don't know what they're talking about. Marine biology isn't just pretty coral reefs and cute fishes. It's hard work and determination -- lots of training. It's very competitive and not very fun. If you're serious, I doubt most of you are, good luck, I gave up on it. I'm a realist so I chose something more suitable. Good luck.

By anon309118 — On Dec 14, 2012

I really want to be a marine biologist, and what I want to do specifically is study coral reefs, and I want to be able to be in the water as much as I can, so what kind of field in marine biology would I be going for? And I'm also 14 and I'm really bad at biology. Would being good in biology help for becoming a marine biologist? I'm also taking latin and I was wondering if that has any value to this field

By anon306810 — On Dec 01, 2012

I am 14 years old and I've wanted to be marine biologist for about three or four years now, but I don't want to go in the water. I just want to take care of the hurt ones and study them.

By anon302479 — On Nov 09, 2012

What's a typical day as a marine biologist like?

By anon294705 — On Oct 02, 2012

I really want to do some hands on marine biology field excursions, but I'm pretty young. Any suggestions?

By anon289371 — On Sep 03, 2012

I have a huge passion for marine life. I want to work on Maui, a Hawaiian island. For the last seven years of my young life, I have seen the ocean's beauty and have learned now how grateful I am for it.

Also knowing this beauty will only be around a couple more decades if we continue to trash our beaches, our Earth, step on coral, and most importantly if we don't realize that through the pollution all over the world, the trash will always make its way to the ocean, taking into account that it is 70 percent of our magnificent earth.

I am pro environment and have a driving passion to find new ways to make our earth less polluted in modern, eco-friendly ways of living. So due to my passion, I believe as a senior in high school, I've found my major, hopefully as a marine biologist specializing in rehabilitation of injured marine mammals or protecting the environment.

I know through our actions as humans, we have consequences to face, but I hope if enough of us start to realize the importance in respecting our mother earth, we can spread influential and positive actions to help this earth and we can keep our earth from declining more.

I'm in the 8th grade and my teacher this year asked me what I want to be and I realized I want to be a marine biologist since I love animals and the water.

I would be a vet but my allergies are too severe and I live in Louisiana and there's nowhere I can go to get any head start on my dream career. Can anyone help give me ideas to get a little idea of what I'm getting myself into?

By anon279736 — On Jul 13, 2012

My name is Lindsey and I am 12 years old. I'm not sure whether or not marine biology is the right track for me. I love animals, but I don't like the ocean. I want to protect animals from beach waste and pollution- not just sea creatures, but all animals.

I want to know if there's any good blogs, sites, or quizzes that will give me information on these creatures and if it's the path for me.

By amypollick — On Jun 21, 2012

@Haney: Like any other degree, the easiest way to find universities that offer it is just to look online. There are dozens of universities in the United States that offer a marine biology program. I found 10 sites with one search.

Most schools have websites, usually with the catalog of course requirements online, or you can contact the admissions office and have them mail you a catalog.

By Haney — On Jun 21, 2012

I would like to know how to become a marine biologist, or if possible, can anyone tell me which universities offer this?

By anon275372 — On Jun 17, 2012

My name is Tyler and for a long time I have wanted to study Marine Biology, but for one particular reason: because I would like to handle marine mammals and help them feel better if they are injured.

As I was reading this article, I saw that you could help marine animals, but the last sentence or so said that marine biologists do not handle marine mammals and I got really worried. So is there any way that I can find the truth?

By anon274055 — On Jun 09, 2012

I'm a 14 year old girl and I love marine biology. It is not just one of my favorite things to do, but it is my favorite thing to do. I like to study things about marine life. I've never met a marine biologist before and I would love to meet one someday. I love looking at things through a microscope.

Do you have any idea where I could go to learn more about marine biology, or study it more? Not anywhere on the coast, but upstate?

By anon268821 — On May 15, 2012

Do they help Marine mammals? One sentence said yes but the last paragraph says they don't.

By anon267887 — On May 11, 2012

My name is Melody, and I am 19. I am currently working with a tourist attraction that features an aquarium, and I have completely fallen in love with our seals and sea lions. I was hoping to get a background in marine biology so that I may work with our biologists, who actually do work directly with the animals. Thanks for the info!

By anon254149 — On Mar 12, 2012

For years, they ask us what we want to be when we grow up. I say I want to be a marine biologist. Mostly, the only reason I want to become a marine biologist is because of my favorite animal, the shark. I would love to be in field study because I think sharks are awesome.

By anon244244 — On Jan 31, 2012

At the moment I'm a junior in high school and I've been wanting to work with dolphins and study marine life since I was 12. It's always been my dream. I'm taking many science classes.

At the moment, I work at the shedd aquarium in the city where I live and it's an internship. It totally is helping me get to where i want to be. I love the marine life and it's just the most precious thing in my life at the moment.

By anon241821 — On Jan 20, 2012

My name is amber. I am 12 years old and I would love to become a marine biologist. Ever since I was little, I have. I want to know what college is best for that job. I will be the first girl to go to college in my family. So I am very exited and can't wait.

By anon230052 — On Nov 17, 2011

I'm Kyla. I have always wanted to work as a marine biology since I was little. Are there any camps I can go to, and also I read this for a science project! How does Marine Biology help make decisions in society today? Please help me!

By anon221803 — On Oct 13, 2011

I am in the eighth grade and I would love to be a marine biologist when I am out of high school. I live in alaska so it is the perfect place to be a marine biologist. I want to go to seward to work at the sealife center.

By anon217475 — On Sep 25, 2011

this is a very good website. it gives a lot of information. i can't wait to be one!

By anon212911 — On Sep 09, 2011

Marine Biology seems to be a peak interest for many young girls. I am 16 and my name is Talia, from Australia. I love the water, never used to love the beach but now I do. I understand that the water and current can be crazy, but when you find places where the water is peaceful, the feeling is so relaxing and amazing.

I wonder if scuba diving in tourist areas would be more my thing, around the Islands, and I want to travel to tropical places, where there is beautiful water, weather and of course, to work with animals. I am also interested in saving the creatures from extinction and captivity. The thing is, sharks have always frightened me. I used to have bad dreams about them and I wonder if it has anything to do with my future.

The first thing I think about when I think about marine life is that I want to swim with them, and I understand not to scare them, but if many jobs allow this, again saving them and researching them is an interest.

Is Marine Biology studied in colleges or universities and if university, then what is the atar requirement, and I am guessing you would need to have studied science for year 11 and 12 which I haven't done, but could I get a back up class at uni, and I am doing general maths, which I suppose is required.

By anon200555 — On Jul 27, 2011

I want to be a marine biologist real bad.

By anon193649 — On Jul 05, 2011

I'm Emily. I'm 19 years old. I was really set on physical therapy for the past few years, but I've always kept marine biology as an option. I've thought about being a marine biologist since I as young but was always told that it wasn't practical. I've very passionate about both of my choices but I don't know which one to choose. If there's any advice you could give me I'd really appreciate it. Thanks!

By anon191829 — On Jun 29, 2011

I am only ten years old but I really want to make a difference in people's lives and their learning. I love ocean animals also!

By anon181001 — On May 28, 2011

Just wondering, if you become a marine biologist, do you work with animals in the ocean? I am considering it as a job in later life because i find like coral reefs and underwater views beautiful. please help.

By anon174276 — On May 10, 2011

I'm a marine biologist. Just consider that 1) it is an incredibly rewarding career, but there are trade-offs with two to four extra years of college and then average pay afterward (unless you become a university professor, which is incredibly competitive); 2) try your hardest to be good at math; it is a huge advantage in this field.

By anon170487 — On Apr 26, 2011

I am currently 13 and love to study marine biology and the vast oceans. Ever since i was about four, I loved sharks and different types of sea creatures. I would love to one day become a successful marine biologist and explore oceans around the world. I would definitely want to be a marine biologist when I graduate college!

By anon169788 — On Apr 22, 2011

I'm Skye and I'm 12 years old.I love ALL animals but I seem to have taken a particular interest in marine life. I'd like to study reef life. Even though I'd like to learn mostly about reefs and the environment around i like learning about most other marine animals. I'd like to know how many years of college it would take to be a marine biologist.

By anon166699 — On Apr 09, 2011

I'm 14 years old and just a freshman in high school. Everyone keeps talking about how we need to start thinking about college now, and there's a lot of pressure to go to really good schools and get the highest grades possible and get good scores on your future SAT test. It's starting to make me nervous, thinking about what I'm going to be doing for the rest of my life. Ugh, talk about scary. I think this helped, a practical breath of fresh air from a neutral party (a.k.a. someone other than parents and teachers).

By anon166470 — On Apr 08, 2011

I'll make my intro short and sweet. My name is Danielle, age 14, and I've been doing research papers for school on sharks with a lengthy 32 pages. Well, I've been obsessed with sharks since grade three, now in grade 9. I think those movies like Jaws are degrading, and I love how they are built and the way they live. Sadly I am in Canada, but is there any place in Canada for a marine biologist to work?

By anon166463 — On Apr 08, 2011

I want to be a marine biologist, and I'm sure of it. I'm 14 and I live in Des Moines, Iowa. I think its really fun to actually go and study the magnificent creatures that use our oceans, lakes, ponds, etc., and every time you make a new discovery, you help further the scientific field, bit by bit. Who knows, maybe your research will even help save a person's life!

By anon165807 — On Apr 06, 2011

I'm 13, and I've been dreaming to become a successful marine biologist. I want to help save the ocean and its creatures. I want to discover new creatures. I want to do these thing because, it might not only be my dream job. But also making happy at the same time. So indeed, it is a dream job I would really want.

By anon165641 — On Apr 05, 2011

So i kind of have a problem. I absolutely love being in the water. But, I also love horses. And I'm 15 and graduation is right around the corner. So, i was wondering if you could give me some career ideas to look at that have to do with lakes and fish.

By anon165410 — On Apr 04, 2011

I am 17 and a junior in high school. I have to make my college decisions pretty quickly and this really helped! This is definitely what I want to do. Hands down!

By anon165003 — On Apr 03, 2011

My name is Brandon, I am 13 years old and i have wanted to be a marine biologist for years. I take ocean camps every summer at A&M Galveston In texas and I live in houston. I already know that i want to major in marine biology in college and move to australia after college near the great barrier reef to study.

By anon162959 — On Mar 25, 2011

I want to be a marine biologist, maybe. I don't know what I want yet. I'm 11 and some of it freaks me out. Is there any position on this sort of work that doesn't require you to always be with those animals? Some of them are a little scary. Okay, really scary.

By anon162792 — On Mar 24, 2011

i'm 13 and i love the ocean and mammals inside of it. i don't live by the ocean at all. I actually don't live anywhere near water, but i still have a passion for water and that will never change. i want to learn more and more so i will be a marine biologist in just about 10 years, maybe less.

By anon161573 — On Mar 20, 2011

I'm 14 years old and I've had an interest in oceans and sea mammals since i was little when i started going fishing and snorkeling. I became even more interested when i first went to marineland in cannes and actually saw real orcas and literally petted dolphins and sharks! so i found out the only thing I'm interested in is to be a marine biologist. will that help? and i also want to know if that could be such a great job for living, as in a high amount of money.

By anon158570 — On Mar 07, 2011

I want to learn all about being a marine biologist because i was born in hawaii which is very close to the ocean and I'm considering being a marine biologist for my future and i might sound older but I'm only 10! So can you please help me.

By anon157429 — On Mar 02, 2011

I'm 13 years old and i have had an interest in sharks since i was about 5 or 6. I honestly have no interest in anything else, but sharks? I don't know if Marine Biology is right for me.

By anon156517 — On Feb 27, 2011

I have been wanting to be a marine biologist since i was 6. The thing is i live in Missouri, nowhere near the ocean. i visit relatives in florida twice a year. I am twelve and i even know what college i am going to the thing is i don't want to wait until college till i have something i can do till then that has to do with marine biology. Also i would also like to know what high school classes to take.

By anon151996 — On Feb 12, 2011

I am 11 am I just recently figured out that I wanted to be a marine biologist. I was wondering do you have to study ocean currents and stuff like that, or just nurse sick marine animals back to health.

By anon144590 — On Jan 20, 2011

I am 14 years old and I love the ocean. I want a career like a marine biologist. I love to swim and I want to be in the water 24/7 and if that is what a Marine biologist does then I will be pursuing this career even longer.

By anon143660 — On Jan 17, 2011

I'm a 10 year old girl. every time i think about what i want to be, it's a marine biologist. what do i need to do to become one?

By anon142676 — On Jan 13, 2011

I'm Francine, and I get nothing less than 95 percent in science and math. I love the ocean so much and I've decided to become a marine biologist when I'm old enough, but I'm only 13 right now.

I love going to the beach in the summer to just watch the ocean and also go in and see what I can find. The problem is that I can't swim. I'm planning on getting lessons this summer but I live in a rural community in Newfoundland so it's hard to travel back and forth to town.

By anon134853 — On Dec 16, 2010

OK I know there are a lot of kids who commented here and said they want to be marine biologists but I think I am probably a lot different from them. For one, I live nowhere near the ocean, which makes me love it even more, and also I have not been interested in marine biology for more then a year which makes me want to make up for all the time that I wasted.

Soon I'm going to take scuba lessons and I'm going to florida once every year, if not more. I'm going to be going to aquariums and lakes. I'm going to learn how to water ski (don't know if that's needed or not) and a lot more.

But, I have researched marine biology a lot and the color of the ocean is even my favorite color. I'm looking at colleges and high schools that may have stuff about marine biology or anything else that is needed and I'm only 12!

The thing is, I feel different from everyone else. I'm not saying I'm better, but I'm saying that I think I have a chance to be a marine biologist that some other people don't have and I am interested in all the animals in the ocean.

Maybe other people don't take me seriously but I take this very seriously. if you have any advice for me I could sure use it.

By anon133510 — On Dec 11, 2010

I'm a 14yr old girl and I'm basically in love with the ocean and everything to do with it and so of course, i want to be a marine biologist.

everyone says you just work with shrimp and plankton and stuff but i want to work with like bigger animals such as sharks and whales and stuff like that, so i was wondering if you get to do that too.

By anon129113 — On Nov 22, 2010

I'm katherine and 14 years old. I have only just realized how important the ocean really is. I know this sound incredibly silly but I love the film Free Willy 2 and after watching it I want to be able to help the animals that suffer from all sorts of things, including oil spills. I know I am 14 but is there anything that you can suggest on how I really could be one? Thank you.

By anon127017 — On Nov 14, 2010

I'm 16 and just decided to be a marine biologist. I love the ocean. It's so magnificent and the relaxing vibe I get when I visit the beach. However I don't know how to swim. I'm going to sign up for a swimming lesson in our local pool. To add I take Biology and Maths now. But do you guys think I have a chance to become one?

By anon126025 — On Nov 11, 2010

I am a 12 year old girl who loves marine biology. I have done research in the ocean and how it affects our poor animals. I love the coral reefs the most. What classes should I take to be a marine biologist?

By marineabbey — On Nov 04, 2010

Not to be mean but please don't stop reading this. i am a 14 year old girl who is studying the facts and researching marine life and also studying the abiotic things such as the ocean. i have wanted to become a marine biologist from the age of 8; that's seven years. I'm doing the best i can in math and science and ELA. I have never met a real marine biologist before. That is because i live in labrador, lance au Clarie. I am a teenager but I'm not like the kind you see every day.

I'm more into marine bio than anything else. I'm a great swimmer, and in the summer i would go out to the beach every day to do studies. i love swimming and sea life. so far i have been studying the coral reefs. i have done an essay on one, too.

do you think in any case i could be a marine bio. Please do tell and what age do you think i could become one.

By anon123609 — On Nov 02, 2010

I am a 13 year old girl who absolutely loves the ocean and mostly everything in it! My best friend and I have been reading mostly everything about Marine Biology! We are hoping to become one some day.

We want to study everything. But the reefs most of all. I know we need a lot of math and science, but are there any other classes that we would need to take to get a better idea of it? What would we do if we don't live next to the ocean? We are land locked. Well thanks!

By anon123547 — On Nov 02, 2010

so what subjects do they study? that's what i want to know.

By anon117272 — On Oct 09, 2010

I am a 10 year old girl. I love marine life a lot. my favorite subject in school is science.

By anon114293 — On Sep 28, 2010

For those of you who are still in school, here are a few ways you can get involved in your community with marine biology. I currently just graduated from high school and am working on getting my PhD. in Marine Biology and a Masters in Environmental Geological Science.

Here are some ways that I was able to get involved, and that you can get involved:

1) Join your local FFA chapter. Yes that’s right, I said FFA. This organization is not just for farmers and what not. Here you will have many opportunities to work with and help teach other kids about what you're passionate about. I have been involved for four years and have done many things with my local chapter. For instance, every year I help teach local elementary and middle school kids about fisheries, pollution, coral bleaching, etc. I was also able to get my chapter to raise salmon, so that we could release them in the wild. These are only two of hundreds of things I was able to do with my chapter, and the best part about it was that I got to do it with people my age.

2) Join your local Beach Watchers program. For those of you who live close to the coast, or large body of water. This will help you get practice in the field.

3) Volunteer at an aquarium. This not only looks good on your college resume, but it’s also a great way to keep yourself educated. Also it’s a great way to get your foot in the door for a career in this field. once they see how passionate you are about it and how dedicated you are, they will more than likely offer you a job.

4) Check into your local Environmental Services Section, and see if they have any internships or volunteer projects. You will be surprised how many marine biologists are employed there. I did a volunteer project at my local Environmental Services Section for a senior project this past year and had a blast. Not to mention I learned a lot about becoming a marine biologist.

One thing you guys need to realize, is that there are not many jobs in the field of marine biology, even though the world is about 74 percent surrounded by water. A lot of the jobs include sitting behind a desk, four days out of five. However don’t let this discourage you. Follow your dreams!

By anon113304 — On Sep 23, 2010

I'm 12 years old and i love physics, math and science and i love animals and really want to be a marine biologist. i got started liking marine biology when i did a project on a project for science. she said we had to do a project on a type of science so i was going to pick either marine biology or astro physics and i decided on marine biology because i like animals a lot!

By anon109929 — On Sep 09, 2010

I'm a 14 year old boy who loves marine life. right now i have a ten gallon tank with seventeen fish in it and later I'm hoping on getting a 300 gallon tank with fish from the ocean. i hope one day i can be a marine biologist.

By anon109700 — On Sep 08, 2010

i really enjoy marine biology.

By anon109340 — On Sep 07, 2010

I am 16 and I would like to become a marine biologist. I feel that my great interest in Marine Life and ecosystems would make marine biology a fun and interesting career.

By anon103573 — On Aug 12, 2010

I've been scuba diving since i was 12 and am well on my way to becoming a divemaster. I want to go into marine research (hopefully off the coast of florida or in one of the research labs in the bahamas) but I'm nervous about college and not getting a job. To any marine biologists or students reading, their advice would be much appreciated.

By anon100207 — On Jul 29, 2010

I'm 14 years old and I come from Bulgaria. I want to become a marine biologist, but there are no opportunities in my country. Have I any chances of becoming a marine biologist? Which are the best universities? Help.

By anon96054 — On Jul 14, 2010

I've want to be a marine biologist since I was in second grade. i am in third grade now. The reason I want to be a marine biologist is to uncover a lot of new discoveries.

Well i also want to become one because i love sea animals. i just think they are much cooler that land animals but still i live both.

Most people in my class think i want to become a marine biologist because i love dolphins. Well, that is not true even though dolphins are my favorite animal. So i hope all of you understand why i want to become a marine biologist.

i am a 14 year old girl and i have loved marine animals most of my life. my favorite is the great white shark. since i was 4 i have had a poster of a great white shark on my wall. I'm always reading books, articles, etc. about great whites to learn all there is to know about these creatures so i hope one day i can become a marine biologist with them.

i am 14 year old girl and i love learning about marine animals, especially dolphins. I am very interested in this job and i hope that i get to work as a marine biologist someday.

I am 13 years old and I am working on a school project. In this project we tell our teacher what we want to be when we get older. Obviously I would like to be a marine biologist.

What exactly do they do? Of course they work with fish, but what else do they do? I would also like to know what courses you should take in college. Also, as you go farther in your degree (I would like to get my Masters and Doctorate), does your job description become different or in every level of degree do you do the same thing?

Thank you for reading this and thank you for your time.

I am currently 11 years old and i am interested and want to be a Marine Biologist. So i need math and science, huh? I'm really good at math and good at science. I'll have to look up more about the subjects i need to take. Thanks for the people who wrote this. Thanks

i love animals and since i was five i wanted to be one and we are doing a project at school on what we want to be and i still want to be one. I'm only 13 now but i still love animals and nemo!

my son is only 11 years old and told me today, that when he grows up he wants to be a marine biologist. i hope he goes all the way with his dream.

By anon82611 — On May 06, 2010

In marine biology, do you have to work on studying currents and things like that, or can you just focus on the animal life?

By anon81545 — On May 02, 2010

I'm currently 16, and to become a Marine Biologist is my dream. I've always wanted to pursue a career in this field. I love animals and would do anything to save them from the dangers of the world. I'm so thankful that there are so many people in the world that feel the same way that I do.

By anon81444 — On May 01, 2010

what percent of marine biologists are happy with their jobs?

By anon81111 — On Apr 29, 2010

I am 13 and I have always had a love for animals but even more for marine life. I would like to know what it is like to have such a amazing job.

By anon76980 — On Apr 12, 2010

Some marine biologists find marine animals that are in distress (like stuck, or injured, or sick) and nurse them back to health. Is that dealing with animals?

By anon76949 — On Apr 12, 2010

You help animals which in a way helps people.

I've wanted to be a marine biologist since I was in fifth grade. I'm in seventh grade now. So I'm wondering if I wouldn't have to go underwater and swim so much as stay in labs and study things. Can you do both? or just one?

By anon74183 — On Mar 31, 2010

I'm in seventh grade doing a school project. One of the three careers I had to choose from is marine biology. I love the idea of a whole entirely separate world underwater with fish, plants and animals instead of humans. It makes me feel alive going underwater, whether scuba diving or just swimming around.

By anon74084 — On Mar 30, 2010

I'm 15 and I've always had a love for animals, but with marine life there's just always been something more. As a little girl I loved watching the little mermaid. I wanted to be just like her, swimming in the ocean. I hope to someday become a marine biologist and do my part to protect and conserve marine life and habitat.

wiseGEEK overall helped me with a school project.

i am i6 and i live in florida and i want to be a marine biologist. It is fun to swim near reefs and in the ocean. it is so wonderful.

By anon72712 — On Mar 24, 2010

Thank you for the article; it answered a lot of my questions! I am trying to decide on a future job and marine biology seems to fit the bill. My only question would be which colleges do you recommend that have programs for marine biology. Thank you again - M.A.D

I'm in ninth grade and I've been watching "free willy" since i was little and it made me want to become a marine biologist. i really like killer whales. they're really cool and i know they're the biggest in the dolphin species. i plan on going to alaska for college.

By anon70792 — On Mar 16, 2010

I'm 16 almost 17 years old and i love marine biology. i think the underwater life is beautiful.

By anon70020 — On Mar 11, 2010

marine biology is about fish.

By anon69603 — On Mar 09, 2010

i am an eighth grader and this article has helped me and i have always wanted to do marine biology since i was four.

By anon67234 — On Feb 23, 2010

I'm in eighth grade. I've had a lot of career choices at first it was a spy or an fbi agent but i think i want to be a marine biologist. it's my dream, but does a marine biologist train animals? (dolphins, seals..)

By anon65318 — On Feb 12, 2010

I love marine biology, I'm in sixth grade and i love science, especially when it's about marine life. And whenever I'm interested in something i like to do research about that certain subject.

One day i hope to become a marine biologist. i love bright, interesting colors and patterns.

I also want a salt aquarium for saltwater fish. Later I'll let them go. Marine biology rocks! -Allison

By anon65234 — On Feb 11, 2010

I have had a desire to be a marine biologist for a while now. But I don't really live by any oceans. Where exactly would the work location generally be? Florida?

By anon62989 — On Jan 29, 2010

what is a good college for me to go if i want to be a marine biologist?

By anon62968 — On Jan 29, 2010

i so want to be a marine biologist but everybody laughs at me and thinks it's a stupid idea and says i should be an actress or singer or be rich, but i love this stuff and am amazed entirely with sharks.

By anon60652 — On Jan 15, 2010

I am 12 years old and i have always wanted to swim with a great white shark. I'm a girl and when i tell people my dream they tend to laugh. I really really want to swim with sharks and discover new things about them! How do i get through this? x

By anon55507 — On Dec 08, 2009

Marine Biology is simple, yet complex. It is ideal for many people who want to live a happy life as is Zoologists. It is pretty straight forward (your tasks) but it is all right. I always want to be a marine biologist and at geelong college you have a good choice of profession.

By anon46744 — On Sep 28, 2009

marine biology is the study of organisms in the sea! you can get it from the name! marine is water, bio means living and ology means study of! so put it all together and it is study of living things in the water. Don't you know your greek and latin! that is a huge part of marine biology too -- being good in english or any other language!

By anon46743 — On Sep 28, 2009

where and when specifically did marine biology start?

By anon45013 — On Sep 12, 2009

How does marine biology connect with biology itself?

By anon44951 — On Sep 11, 2009

I'd love to become a marine biologist because my teacher said you get to go deep in the ocean. But seeing sharks is my worst fear.

By anon44950 — On Sep 11, 2009

I'd really like to be a marine biologist. But how is zoology connected to marine biology?

By anon43227 — On Aug 26, 2009

I am going into the sixth grade and i have always wanted to do something with dolphins. my dream job is to work at sea world!

By anon43099 — On Aug 25, 2009

Yes, a marine biologist does handle marine life. a dolphon trainer is a marine biologist. a marine biologist is a form of zoology but so is a wildlife biologist and etc. I am sorry but you are wrong about that. In fact most marine biologists handle marine life including the mammals such as dolphins.

By anon42385 — On Aug 20, 2009

This is a pretty "in a nutshell article". I actually think i'm going to pursue a career in zoology knowing now that they work with animals; animals such as sharks..which are my favorite =) -shelby

By anon40771 — On Aug 10, 2009

i'd like to be a marine biologist

By anon40770 — On Aug 10, 2009

i'm going into the sixth grade and my whole life i've dreamed of being a marine biologist! i really don't want to swim with sharks because i have a fear of them but as i get older i would want to discover non-existing sharks and i wanted to know can i do a summer program in the next summer 2010 because i want to know if i'm to young to swim with dolphins and or train them or discover new fish. i'd like to know. thank you again. i maybe hopefully will be a marine biologist like you! :)

By anon40423 — On Aug 08, 2009

i'm going into the seventh grade and i love all animals land and water. but i love the water animals more. i want to become a marine biologist but i want to know do you have to swim with sharks? because that's my dream to swim with sharks.

By anon39883 — On Aug 04, 2009

I am only going into 6th grade but I think I really want to be a marine biologist because I really like marine life and think fish are quite interesting.

By anon38666 — On Jul 27, 2009

What safety clothing do marine biologists have to wear? What equipment do they use? How do they help other people? What do you think would be the best part of their job?

By anon37534 — On Jul 20, 2009

I love Beluga Whales. But I want to be a marine Bioligist. Also I want to be a beluga whale trainer. what should I do?

By anon32843 — On May 27, 2009

By anon25717 — On Feb 02, 2009

How many years does it take in college to become a Marine Biologist? 8?

By anon25314 — On Jan 27, 2009

I am in high school and i am very interested in ocean life and marine animals. this be the right career for me?

By anon22367 — On Dec 02, 2008

its not about helping animals if you want to help animals become a zoologist. and marine biologist can have a affect on people in a good or bad way

By anon21052 — On Nov 09, 2008

marine biology isn't about helping people, it's about helping animals but a marine biologist can help make a better person to conserve our environment and ask you not to litter, etc.
