Do you have questions for a marine biologist?

Send them as an email (subject: ask a marine biologist).

To read samples of previous questions and answers, see comments below or click here: “Ask a marine biologist

(Note – I used to accept questions as comments on the webpage but now I recommend sending as an email.)


Question topics in the past have included career choices, marine life identification, deep oceans, coastal ecosystems, coral reefs, sounds, current events, and information for school assignments.


Please review these Frequently Asked Questions (FAQ)



1. What inspired you to become a marine biologist?

Music, actually. I was very interested in sound, which led me to be interested in bioacoustics and I did my senior project in college on snapping shrimp. That is when I decided to focus on marine biology, which is all about life in the ocean that live in a ‘world of sound’ because marine ecosystems are so dependent on sound. Sound travels four times faster in water than in air! Marine animals use it for communication, defense, navigation, even ‘sight’ through echolocation. (Looking back, I can see earlier signs that marine biology was a good fit for me. I was fascinated by the beach, and aquariums. I remember as a kid spending several hours watching a crab walk around in circles!)

2. What education is needed to become a marine biologist? What education have you completed?

There are few marine biology jobs that are actually labeled “marine biologist.” There are many types of marine biology jobs and it depends what you want to do. Maybe you want to lead SCUBA nature tours, or manage fish stocks, or film documentaries, or consult with aquariums, or influence science policy. Most marine biology job seekers would benefit from not only a high school education but also a college education in a related field – it could be marine biology, or it could be biology, physics, ecology, etc. Further specialization with a masters would probably be beneficial. There are two main types – research based (usually an Master of Science), and not research based i.e. class based. If you want to work in academia, and/or lead your own research programs, and/or be a part of shaping the field not just working in the field, you might want to consider a doctorate degree (PhD). You can get a masters first after college, or go straight to a PhD program.

For undergraduate (college) I have a BS in Biology with a minor in physics. For graduate school, I have a MS in Marine Biology, and a PhD in Behavioral Neuroscience. Along the way I also picked up a Masters in Psychology. Eleven years of school after high school is not for everyone, but it was a good path for me. Between my MS and PhD I did a fellowship in Mexico.

3. What is a usual day for you?

My days are different since the quarantine. Most of my work with colleagues is now by zoom. My research is on hold since I cannot get to my field sites. My work is a combination of science research, marine renewable energy, science-art collaborations, and conservation.

4. What advice would you give to people who want to become marine biologists?

Follow your interests, read, talk to people, get involved.

5. What is your favorite marine species?

All marine species are interesting, and within species, every organism is an individual. It’s truly amazing to work with creatures of all kinds. Snapping shrimps are real characters and so are dolphins.

6. What research would you love to conduct?

My dream research project is to (continuously) record the sounds of the reefs of the world.

7. What is this thing I found on the beach/in the water?

Feel free to email it to me, I may or may not be able to answer it myself and may ask a colleague. If you think it is or was alive, you can also try the app iNaturalist which is a citizen science tool for identifying and tracking sightings of different organisms.

    1)I need to know the hardest obstacle that got in your way of becoming a marine biologist.
    2)I have an estimated salary, but want to know the actual salary and hear it from a marine biologst.
    3)How many job opportunities are available?
    4)What does a marine biologist do on a daily basis?
    I hope you have the answer to a few of these things. Any information on this career will help. Thanks!!!

    Hi Bret, nice to hear from you.

    Obstacle – Hmm… well, I did go to an undergraduate school that was landlocked! But, I did my senior thesis with the one marine biology professor. I did a lot of traveling, and then back at the lab I spent a lot of time making sea water. It was… definitely challenging. 🙂

    Salary – Sorry but this is not something that I discuss. There is a wide range. I can say that marine biologists generally aren’t in it for the money!

    Job opportunities – Many and varied, there are lots of direct and indirect marine biology related jobs, anything from scuba instructor to scientist at an aquarium to professor at a university to government to companies to…

    What we do – again, depends. Generally tons more time spent on the computer than in the water though – so it goes. 🙂

    Hope this helps

    There are many different kinds of jobs – some involve field work, some lab work, some are policy-related, some are research based, some educational, some deal with drugs, or animal behavior, or conservation – deep water, coral reefs, climate, shipping, invasive species…. so there is more to it than just that 🙂

    Dear Amanda,
    Thank you for your questions. I am glad you are interested in marine biology.
    Science is fun for me! I always enjoyed exploring the world around me, examining bugs and leaves and puddles. Many children are wonderful scientists because they are curious.
    When I was in 6th grade, I didn’t like math very much, but then I took a test and in 7th grade I was in a math class that was more interesting. That was important because many science classes require math and I wanted to study science. I took chemistry, physics and biology in high school. In college, I took lots of different courses and then decided to concentrate on biology. In graduate scool, I specialized in marine biology.
    My interests in marine biology include talking to people about how to be considerate of the Earth. I have taught lessons in schools and published papers in journals, all to try to help people be excited about the amazing world around them. When people understand the effects of their actions, they mostly try to do the right things.
    Right now I am in school myself. I have a master’s degree and now I am working on my PhD. My resonsibilities are probably similar to yours, because I want to be sure to get everything I can from my classes and my teachers, and the other students.
    When I do my research, I need boats, diving equipment, computers, and a laboratory where I can return to analyze my data.
    Marine biologists are discovering many new things about the deepest ocean trenches and the pollution that people create and the needs of various sea creatures. We know less about the ocean than we do about outer space, because we have not spent much time or money finding out. But now people are realizing how important it is.
    In my work, I never choose favorites because all the animals are very special. When I studied tiny shrimp, I found out they were interesting individuals with different personalities, even though they were small. Now I am studying dolphins and of course everybody knows they are very smart. The animals I work with teach me many things and I like them all.

    Dear Emily,
    Thank you for writing to me. I am glad you are interested in finding out about whales.
    Blue whales, and other whales as well, are endangered because they are losing the things they need to be healthy and have babies and survive. They are very large and need a lot of room to live and grow, but even though the oceans are huge, people are causing problems for whales by dumping poisons into the air and water, and destroying some of the special places where they like to raise their babies, or find food. Whales swim long distances, but they cannot find what they need everywhere.
    If you want to save whales, remember that small actions make a difference. You can walk instead of driving, recycle, think about the things you do and how they affect the ocean. Ask questions. Do you know where your electricity comes from? Do you know where your trash goes? The more you know about yourself and your needs, the more you can do to help whales and other marine creatures.
    Whales have been endangered for a long time because people weren’t paying attention to how our actions affected them. By the time we realized they were disappearing, there were not many left. Now scientists study whales and are learning more about them. International groups decide on ways to protect them.
    One simple thing that can be done to help whales is to use less. Less plastic, less electricity, less water, less lawn chemical, less oil – you get the idea? You don’t have to suffer, just reduce waste. The more people who do these things, the more we all help whales.
    Also, of course, we need to be considerate about using the oceans.
    As a marine biologist I am always thinking about the effect of what I’m doing. The more you learn about the oceans, the more you understand how everything is connected.
    Whales get beached when they are sick or injured and cannot swim anymore.
    I hope healthy blue whales will be swimming in the oceans for a long time, and I am happy to tell people how they can help make this possible.
    I do not personally work with blue whales, but if you look at my website, you can see some of the things that I do.

    My wife & I just got back from a vacation near Tampa Bay, FL. We rented a boat & went out near Egmont Key for a day in the sun & some dolphin sight seeing. We had seen plenty of dolphins all week long, but on this particular day, we saw what we initially assumed to be just another dolphin cruising around in the sandbar shallows about a mile north west of Egmont Key … but as we approached & looked a little closer, we noticed it was larger than any of the dolphins we had seen all week long, & was moving very slowly & differently than any of the dolphins we had seen. I was able to get one photo of it’s dorsal fin just before it scurried off into deeper water. Even the dorsal fin looked unlike any of the other dolphin dorsal fins we had seen all week. The size, movement, & dorsal fin shape made us start to wonder if perhaps it was actually a large shark rather than a dolphin, but upon getting back home & viewing our one photo on a large screen TV, there appears to be a blow hole on top (like a dolphin or whale would have) … of course the curiousity is killing me. If I sent you a photo of the dorsal fin, do you think you would be able to help me identify what it is? If you’re interested & willing, then please send me an email so I can reply with an attached copy of the photo. Thanks 🙂

    Hello, I am trying to contact a biologist at your location with specific questions regarding dinoflagellates in a reef system. Please pass this along to whoever can help. Thank you.
    Myself and thousands of other hobbyists have been fighting a never ending battle with this “pest” and many are quitting the hobby due to this. We are trying to devise a way to rid our tanks of this nuisance and are looking for some helpful insight or a cure for this. Here is a link to our current thread on

    To sum up a couple of the posts, people have tried using h202, increasing PH to 8.5, aggressive protein skimming etc. just to name a few. Please help us if you can. Any and all help you can provide will be of great importance to us. Thank you.

    Dear Ethan,
    Thank you for your questions> I am glad you are interested in becoming a marine biologist. Marine biologists work on many things, from deepest seas to shallow coastal waters, from the icy poles to the tropical beaches. You can look at my website to see some of the things that I do.
    In Ohio, you are still connected to the ocean because all the Earth’s water and land is connected. If you want to study the ocean, begin by learning about science, and take classes in chemistry, physics and biology. Learn all you can from books and people. You don’t need to go into Lake Erie to learn about it, but you do need to ask questions and find out what interest you. Then when you are ready for college, you can explore further and decide if marine biology is right for you

    Dear Jennifer,
    Thank you for writing to me with your questions. I am very glad you want to be a marine biologist. I think it is a great career. I get to do the things I like most. When I was in 6th grade, I thought wanted to be a scientist, but I didn’t like math very much. Then I took a test and in 7th grade I was in a more interesting math class. I liked science and studied chemistry and physics as well as biology. In college I took lots of different classes before I decided to concentrate on biology. Then in my senior year, I did an amazing project on a tiny little shrimp that makes a lot of noise. I was so fascinated, after I graduated, I went to a college near the ocean and got a master’s degree in marine biology.
    Studying a lot is part of being a marine biologist and even when I was not in school I was working and learning. Now I am studying to get my PhD. You don’t have to have a PhD to be a marine biologist but you might want to.
    The job description is almost anything that interests you. And the career path, too. You might like deep water and go far out to sea, or shallow water near the shore. You might like warm water or examine the polar areas. You could work for a drilling company or the government or a non-profit such as Conservation International. Marine biologists can choose from a lot of different jobs, and may spend their time on boats or looking at a computer or in an aquarium.
    If you look at my website, you can see some of the fun things I do.
    Best of luck!

    Dear Allegra,
    Thank you for your excellent questions. I am always glad when students are interested in the ocean.
    The Great Barrier Reef is very well known, but many people have not even heard of the second largest reef system in the world which is in the Western Hemisphere: the Meso-American reef.
    Reefs are threatened by many things and scientists may not agree about which are the worst since all are a problem. People are responsible for causing damage to reefs, not because we want to, but because we don’t understand the effects of our actions.
    Toxins in the water and air, temperature changes, trash, invasive species, noise and light – all of these can be harmful to coral reefs.
    Coral bleaching is what we call it when part of a reef dies and the coral looks white, like a skeleton, which is what it is. All the animals and plants that were living together because of the coral, die or go away. We know that ‘stress’ causes coral bleaching but stress is just the name for a reaction to a disturbance and there are many things that cause stress, as I mentioned above. In 7th grade, you are already already able to understand a lot about interactions that are harmful. I hope you will continue to be interested in the Earth’s ocean ecosystems, and to explore the best ways to protect them.

    Dear Sam,
    Thank you for contacting me. I am glad you are interested in a career in marine biology. There is a lot that needs to be done!
    This field is very broad and you can find many different jobs as a marine biologist. For example, you might work for the government or a non-profit or a commercial company, or an educational facility.
    My work is at a university and I do research and teaching. My schedule varies from day to day. Sometimes I am in a classroom, or a lab, and other times I am on a boat or diving under the ocean.
    To become a marine biologist, you need to study a lot of science and after college, you will need at least a Master’s degree. The money that you make will depend on where you decide to work and what you do. It is not a specialty that generally pays as much as say, Law or Medicine or Engineering. I became a Marine Biologist because I love the work, and I didn’t mind not always making a lot of money.
    I get to meet and work with interesting people from all over the world and I get to be outside on and near the ocean. Because there is so much to learn about the environment of the sea, there will always be plenty of work for marine biologists.
    If you want to be a marine biologist, you will need to study and do well in your science classes. Choosing an independent research project can be a way to explore what interests you most. I enjoyed doing science projects in high school and in college I was fortunate to get funding for an intensive research project that gave me a chance to really investigate something I was interested in. I even hired other students to help me, which was also good experience for me. You will need to be able to write clearly, to document your work, and present your results. And you will need to publish in peer-reviewed journals.
    If you love what you are doing, this can be a wonderful career: exciting, rewarding, satisfying.
    Good luck!

    Dear Sam,
    A career in Marine Biology is interesting because you can select from many different options for your specialty, type of work, etc. It is not really possible to answer your questions exactly, as if we were talking about a specific job. For example, different jobs have different responsibilities. Right now I am doing research and working in a lab. A few years ago I was an editor and writer at an online publication. Both are Marine Biology ‘jobs’.
    I work every day, but my schedule is different from day to day, and I go to different places. There is so much we need to learn and teach and do in Marine Biology, I think there will always be plenty of work. The only problem is that people have to think it is important or there will not be enough money to pay for the work that has to be done.
    There is no ‘average salary’ for a Marine Biologist. How much you are paid depends on the work that you do.
    My Masters degree (MS) is in Marine Biology.
    I hope this helps.

    My mother went out with her friend kayaking on east greenwich cove, part of narragansett bay in east greenwich. We’ve heard reports of portugese man o wars about. There are these small green almost grape shaped gelatinous spheres. On one end they got these short stringy little tenticle type thing, almost like a stem from a grape vine. Their about the sized of a quarter, In water they retain their shape but when you take them out, they go flat. They don’t sting, she collected them by hand. They are floating everywhere. I’m 23, I’ve never seen anything like them, my mothers lived here for 43 years and she’s never seen them, and my grandfather has lived here for 79 years and has never seen anything like them. I originally thought they were sea gooseberries, to my knowledge though those are clear…these are not. What are they? We were thinking they were man o war eggs. I took a set of 9 photos to aid in identification. I provided my flicker short link as the website to help.

    Hi Frank, Thanks for contacting me about the blobs 🙂 I’m not sure offhand but I’ll take another look and see if I can ID them for you.

    Keep looking out for interesting things, it is often citizen scientists who first discover things like invasive species!

    Hi Heather I was wondering how I would find out the chemical composition of various species of jellyfish, or whatever the rough average is assuming they are roughly the same.


    nitrogen (N)
    phosphorus (P)
    potassium (K)
    calcium (Ca)
    magnesium (Mg)
    sulfur (S)
    boron (B)
    chlorine (Cl)
    copper (Cu)
    iron (Fe)
    manganese (Mn)
    molybdenum (Mo)
    zinc (Zn)

    Thanks in advance

    Hi Jaime,
    Jellyfish are mostly water, I think estimates are at about 95% water. So if that’s what you are looking for, then Hydrogen and Oxygen are the elements!
    Hope this helps,

    I almost mentioned that I knew they were about 95% water, I should have been more specific. I’m curious about what that mysterious 5% is composed of, and specifically the listed elements. If you were to have 1000 kilograms of dried jellyfish, how many grams/kilograms would you have of the 13 listed elements.

    I did a search on google scholars and it looks like there is a paper I can buy for a little money that may have some of the data but I wouldn’t know till after I bought it, and was just wondering if I could contact a marine biologist online somewhere that could get me the info.

    Hi Jaime,
    What is this information for? Are you doing a chemistry project? Are you interested for nutritional purposes?
    There is a lot of research published on the chemical composition of cnidarian mesoglea, if that helps your search. E.g.
    Also, if there is a particular paper you are interested in, you might contact the authors directly.

    Well Heather I’ve been aware of the rapidly multiplying jellyfish populations for a few years now. I guess due in large part to overfishing of their natural predators and increased ocean temperatures.

    I was wondering if there was a way to maybe help out the oceans ecosystems to not be totally overrun by the jellies, in a way where you could kill two birds with one stone. I figured they are made of organic material, maybe they would make good fertilizer.

    And with that silly idea I started doing some research as to what elements are important in fertilizer and looking for what elements are found, and in what percentages, in jellyfish!

    Hi Meghan,
    There are many types of pollutants in the ocean – plastics, fertilizers, noise… You might try looking up about plastic pollution, because it is a huge problem and there are a variety of organizations you can find on the internet that write about it, such as Surfrider Foundation and their program Rise Above Plastics

    There’s a squid the Japanese eat which comes to life when you apply soy sauce. The dish name is Odori-Don. Some web-sites say it is actually still alive, but many ask, How can something be alive without a head? So they declare it must be dead! Personally I’m thinking it must be alive, but after seeing frog legs animate when salt is applied(or chickens running with their heads cut off!) I am confused. I was thinking a Marine Biologist would know, so is this thing dead or alive?

    Hi Matt,
    Thank you for contacting me. I am glad you are interested in Marine Biology. The squid in the dish you refer to, Odori-Don, is undoubtedly both dead and alive. Without a head, it is dead as a squid, however many of its cells are still alive and various parts of it are still able to react to stimuli. And of course there are plenty of living microbes. Don’t be confused. The essence of life as we know it, is that it exists everywhere, on many levels.
    I hope this helps.

    thank you!
    i was just wondering, what is the future of the great barrier reef if the state that its at keeps getting worse, and pollution keeps effecting it?

    what are people doing to help the barrier reef and its marine life?

    Is there a place i can send money that i have funded from a fundraiser?

    and lastly, what is causing the most damage to the reef, is it pollution, the animals or even divers? or tourism?
    also what marine life is in danger?

      Dear Sarah,
      Thank you for your interest! The Great Barrier Reef and the Meso American Reef are the two largest reef systems in the world. These amazing natural wonders are now threatened by various kinds of pollution. The future of reefs depends a lot on the countries that are closest, so it is especially important for people to learn about these precious resources. My work in Mexico includes talking to students about the coral reefs and helping them understand how to respect the reef and live in harmony with it. Healthy reefs protect the coast from storms and provide plentiful fish for food, so there are many ways that caring for the reef is rewarded. Most of the damage is done because of ignorance. People don’t want to harm the reef, but they don’t know appropriate ways to protect it. My research is to discover more about how to keep reefs and marine life healthy, so we can find ways that humans can adapt our behavior to keep from doing harm.

      We always need money! My research involves many people donating their time and expertise but we still need to pay for equipment. I work with Michelle’s Earth Foundation, which is a 501c3 non-profit founded to honor my friend Michelle who was killed before she could realize her dream of helping the Earth. I would be honored if you wanted to contribute to my work. Checks can be made out to Michelle’s Earth Foundation, and mailed to 801 S. 25th Street, Arlington, VA 22202.

      The most damage to the reefs all over the world is caused by pollution, from human carelessness. We wash everything into the water! And just as on land, when air is dirty and trash accumulates, the more delicate animals and plants die; invasive species and diseases overwhelm fragile ecosystems. Humans also do direct damage by removing natural features to make room for development. Reefs are home to many species (shrimp, fish, lobsters, octopuses, crabs…) and when the reef is compromised, the life that depends on it is also threatened. Humans and birds may not live under water, but we interact with and rely on the reef.

      Certain things that humans do are so thoughtless, they deserve special mention. Many people do not know that exploring for oil on the ocean floor involves making huge noises. We are trying to ‘hear’ where there is oil, but we cause terrible pain and suffering to marine life which is very sensitive to sound. Dolphins can be killed by loud noises.
      It is important for people to understand the effects of their actions. Perhaps if people realize the harm they cause, new methods can be found that are more benign.
      This is why I work in Marine Biology research – because I believe we can find solutions and learn to live in harmony with our ecosystems.

    In college, do you want to try to get a marine biology degree right away, or do you want to go for biology and then marine later?

  • by Heather
    Posted August 20, 2011 3:27 pm 0Likes

    Hi Adam,
    Both are fine paths to take. I chose to majore in Biology, and then get a Masters in Marine Biology. This has the advantage of having a broad base, and can give you flexibility. As long as you get a solid science degree, with whatever prerequisites you need for the job/program you want to go to, you should be fine.

    Ms. Spence,
    I hate to bother you. I took a picture of a fish in Lembeh Strait Indonesia. I have not been able to identify it form any fish book. If you have time would you please help me identify this fish. If you do not have time, you my know someone who does. Let me know the email address to download the picture to. Thanks.

    Hello Heather,
    My name is Christine and I am a senior in high school, and I was wondering if you could answer some questions I had about a marine biologist for my project Im doing. If you could get back to me asap that would be great.
    1. Whats the greatest difficulty about being a marine biologist?
    2. How many years of college did you go through and what was your major? What college did you go to?
    3. Are there job opportunities available in this field?
    4. What do you enjoy the most about this career?
    5. What are you currently working on?
    6. Do you work with marine life or is most of your time spent in a lab?
    If you could answer 3 or 4 of these questions, I would appreciate it. Thanks for your time

    Hi Christine,
    Thank you for contacting me. My work in Marine Biology is very interesting and I enjoy telling people about it.
    The greatest difficulty about being a marine biologist is having many important things to do and not enough money or time for all of them.
    My studies were fun because I took classes about subjects I wanted to learn. So far I have 9 years of undergraduate (at george Washington University, Biology) and graduate school (at University of Massachusetts and Hunter College, Marine Biology).
    There are a lot of job opportunities available in this field, especially if you consider finding the work yourself and convincing someone to pay you to do it.
    What I enjoy the most about this career is that I am doing work that I love and think is important.
    My research is on dolphin communication. I am also doing bioacoustic research on how sounds indicate ecosystem health.
    My work is with marine life, both in the ocean ands in an aquarium. Of course I also spend time on a computer in a lab.
    Good luck!

    Hi Heather,I’m Kat and I’ve been trying to figure out what type of tube worm this is for over a month. It’s stumped me, and my college marine bio teacher, and his colleagues, and anyone else I’ve asked.
    I found it in Avalon bay on Catalina island in mid november this year. I’ve lived on the island all my life and go tidepooling a lot but never before have I seen that. The first time I saw it there was only one fairly large one. Then when i came back a week or 2 later to see I saw them everywhere and was able to collect a lot of empty ones. Do you know what it is? Thanks!

    Hi my name is Alexa, and I am a freshman at GWU. I was researching GW’s program for biology because I am interested in marine biology. However, I am also interested in political science and history. I don’t know whether to pursue the obvious GW political track or try my hand at something I’m very interested in, yet know little about. I know I have a passion for marine life and I would want to be involved in researching sharks and orcas. I do not know the best way to go about this. Do you have any tips on how to go about becoming involved in marine biology at GWU and what I can do to know it is the career I want to pursue? Thank you!
