The Marine Mammals

When you think about Marine Biology, what do you think of first? Which aspects of Marine Biology are important, which are essential, and which ones can you take or leave? You be the judge.

Studying marine mammals may be one of the most interesting parts in a marine biologist’s profession. There are 3 main orders that you need to know about. Each category has its own unique mechanism, feeding pattern and characteristics. These animals tend to live in different places as well, others in groups and the rest in families or alone. Once you become familiar with their lifestyle and features, you get to appreciate the species more.

Cetacea Order

The whole lifecycle of the order Cetacea is aquatic. There are a couple of sub-orders founded ont he feeding mechanism – Odonticeti and Mysticeti. The sub-order Mysticeti includes baleen whales, blue whales, minke whales, grey whales and right whales. The whales feature mechanisms to boost the success feeding.

The sub-order Odonticeti includes animals like killer whales, dolphins, toothed whales and porpoises. River and coastal species reside in small home ranges if they are offshore. Others prefer warm equatorial waters, while the rest are located in every ocean like the bottle-nosed dolphins and killer whales. Some animals like big baleen whales move from the tropics for winter breeding to high latitudes for summer feeding. Animals propel themselves using the broad and boneless tail flukes. They also shed skin and exude oil as much as 12 times per day to reduce friction.

Pinnipedia Order

These animals adapt to the environment through a variety of processes. Heat conservation is done and get a low SA/V ratio and develop insulation through their hair and blubber. All the animals moult, after breeding in the summer while the others should stay out of water until everything is done.

The respiration is done by exhaling before the deep dives. They have relatively high concentrations of haemoglobin and myoglobin. The heart of the animals drop during deep dives and the blood is limited to the heart and brain. Dives can be as deep as 1700m, lasting anywhere between 80 to 160 hours.

Sirenia Order

Sirenians are sought mainly for their hide, oil and meat. They spend their entire lives in the water and are the only aquatic animals labeled as herbivores. The flat tail propels itself via paddles. These can walk at the benthic or move backwards. Locomotion is usually slow but they can also burst at around 13 knots. Sirenians inhale before they dive, just like whales.
When they breathe, they can swap about 90% of lung volume.

Manatees can see very clearly underwater, while taste and smell are retained. These touch when they greet each other and lead to chirps, between calf and mother. Dugongs can live for as long as 70 years but fecundity is rather low. The animals reach puberty at 10 years old and produce only 1 calf every 5 years. Their population has to be protected to maintain the ability to recover from environmental stress and hunting.

Interacting with Man

All animals have interactions with man, although sirenians are the most widely known to be friendly towards humans. Fishing nets and fishing lines tend to be a problem for most of these animals.

Choosing the Right Marine Biology College

Are you looking for some inside information on Marine Biology? Here’s an up-to-date report from Marine Biology experts who should know.

There are several universities and colleges offering programs that train students in marine biology. You have to find the best school that can provide you with specialization, as well as open more opportunities to gain substantial income. Keep in mind that there are several kinds and specializations. You should check out the programs and ask other students what you can expect from any given course. Here are some tips on how to pick the ideal one.

Where to Study

Marine biology colleges may be located inland in various states, but you have to expect that you will later on be assigned to offshore sites and many aquatic areas to do research and undergo projects. You should determine the different sites where you will most likely be assigned if you enrol in a particular college. You should also decide if you want to study away from home or just live a few miles away from the school.

Some colleges offer a wide range of marine biology specializations. Others may only have the major marine biology course, while other colleges have 3 or more specializations. Even though a college or university may only offer one kind of marine biology course, you can still get ahead by checking if they have other good programs that go along with the course. If you know some great marine biologists and professors teaching, it can also be a good factor in helping you determine the best college.

The Budget

How can you put a limit on learning more? The next section may contain that one little bit of wisdom that changes everything.

Taking up marine biology in a college will most likely mean paying the same enrolment fees as other bachelor of science course. You will also need to pay for use of special equipment, books, study materials and uniforms. Since the course will require funds to support different types of research, you will be trained or actually apply for grants to help get financial help for your projects. There are many marine biology scholars all over the United States, provided that you have the right credentials and good grades to show your school.

Why You Want to Study

Know your reasons for wanting to study marine biology. Choosing a college will also depend on your current SAT scores, grades, finances and extracurricular activities. The high school guidance counselor can help you discuss the realistic opportunities to get into a good college. It is not uncommon for students to graduate marine biology inland, without even being close to the ocean.

On Majoring

You do not have to become a major in marine biology to be a marine biologist. Basic science can be useful enough, but it is recommended that you take up a course in marine science or take it as a minor subject. You should focus more on the basic groundwork that will help you become more knowledgeable in the course such as chemistry, physics, biology, math and engineering. You should also learn a few things about computer programming and science.

You can also try to take a double or triple major in engineering subjects, since these can directly be applied to problems in ocean science.

You can pursue further studies to become a professor and be assigned to the particular job that you are really interested in. You have to review the different features of the job before applying. This way, you minimize the time exploring and focus more on the aspects that can both fuel your passion and earning capacity.

The Research Coordinator

The managerial positions can land you a salary of about $75,000 to $100,000 each year, higher positions in institutional management can even reach up to $150,000 each year. As a research coordinator, you will need to create a sound expedition plan. You will also go on ships and submersibles. The work includes gathering of data and samples. The job can mean collecting invertebrates then getting extracts back at the laboratory. The extract will be checked and observed as well. Different chemicals found in the extract will be tested on different human diseases to know if there are any changes that can potentially treat.

The job requires a doctorate degree because of the high level of administrative and managerial work. You do not need to have the doctorate degree if you want to do lab work. You can also land a teaching job instead. Some courses will help you prepare better for the profession such as chemistry, molecular biology and biochemistry.

Being an Oceanographer

If you base what you do on inaccurate information, you might be unpleasantly surprised by the consequences. Make sure you get the whole Marine Biology story from informed sources.

An oceanographer earns anywhere between $100,000 and $150,000 each year. Being a full professor can help you land teaching jobs and get a bigger salary. You will typically work about 60 hours each week. The job description entails creating new graduate programs in oceanography. You have to work with groups of graduate students and continue research in different oceans and seas to boost the telepresence program. You will be tasked to watch, study and gather data from creatures, habitats, sea vents and ecosystems.

Studying Mammals

Marine biologists will have to study different organisms, depending on their location and personal preference. If you become a marine mammal biologist, you have to earn a bachelor’s degree at the very least. However, most people in the position have a master’s or doctorate degree. Salary ranges anywhere between $40,000 and $80,000. The hours per week will depend on the project and deadlines. On the average, you have to work about 8 to 10 hours per day. Some of the work entails studying the ecology of marine mammals. You have to observe the behavior and interactions of seals, whales, sea otters and dolphins.

Study the Habitat

You have to study their environment as well at different phases of their lives. You will spend several months per year writing proposals and papers. You also have to learn how to apply for grants to fund your many researches. You will spend some time on a boat or submersible too, catching, tagging, viewing and counting marine mammals. You may discover some of the rarest species and inform others how to better protect them.

If you’ve picked some pointers about Marine Biology that you can put into action, then by all means, do so. You won’t really be able to gain any benefits from your new knowledge if you don’t use it.

Habitats in Marine Biology

The following paragraphs summarize the work of Marine Biology experts who are completely familiar with all the aspects of Marine Biology. Heed their advice to avoid any Marine Biology surprises.

Marine biology studies the different species, both plant and animal that thrives in the ocean. It is also important to focus on the different available habitats to know how each interact with the environment and deal with the different dangers, benefits and threats that lurk in every corner. Knowing more about the environment will help you categorize species better and find the definite animal or plant that you are looking for. Here are some guidelines.

About Reefs

Reefs are made of some of the most diverse and densest habitats in the planet. The most popular kinds are tropical coral reefs that are present in many tropical waters. Reefs can also be available in cold water. These are created by calcium-depositing animals and corals, in most cases, over a rocky outcrop on the bottom of the ocean. Reefs can also grow on other types of surface, making it highly possible to build man-made reefs. Coral reefs can support a vast life community, including corals, tropical fishes, zooxanthellae and other organisms.

During 1998, coral reefs went through a very rare bleaching event, wherein several reefs all over the world died due to sea surface temperatures rising very high above the average. A number of reefs are still recovering from El Nino, but scientists indicate that more than half of the coral reefs on Earth are currently endangered, with global warming increasing the effects.

The Shore and Ocean

Think about what you’ve read so far. Does it reinforce what you already know about Marine Biology? Or was there something completely new? What about the remaining paragraphs?

The open ocean is not very productive due to inadequate nutrients. Since it is so vast, it only produces the most primary productivity. Majority of the energy in the aphotic zone is provided by the open ocean in detritus form. The open ocean is usually made up of jellyfish, with some predators like the Mola mola.

Intertidal zones are described as areas found very near the shore. These are exposed nonstop and covered by the tides of the ocean. A wide array of life forms exists within the zone. Shore habitats also range from the upper zones to the place where land vegetation is abundant. It can also be found underwater anywhere from daily to very infrequently. A lot of species are scavengers, getting their meals from sea life washed up on shores. Bioerosion is also used by a group of organisms living in intertidal and shore habitats.

The Deep Sea

Very deep oceanic trenches are found in the Pacific Ocean. In waters this deep, the water pressure tends to be very high and sunlight is not readily available. Life still does exist in these parts. Some of the examples include small flounder fish and shrimp. The deep sea is known to begin at the aphotic zone, wherein the sunlight lacks the power of transference in the water. Many of the organisms found in this location have the capacity to produce their own light. A lot of life is also present in seamounts. Unique biomes and several microbes were found in these locations.

On Distribution

Majority of ocean life reproduces in particular areas, spends some time as juveniles in other locations and spend more time as mature species in other places. It is not yet fully known where and when exactly different organisms spend the different phases of their lives. Tracking devices can work but only up to a very limited extent.

Now you can be a confident expert on Marine Biology. OK, maybe not an expert. But you should have something to bring to the table next time you join a discussion on Marine Biology.

Related Fields and Marine Biology

Imagine the next time you join a discussion about Marine Biology. When you start sharing the fascinating Marine Biology facts below, your friends will be absolutely amazed.

Marine biology is a branch of science that deals with the study of aquatic life and underwater environments. You will be assigned both inland and offshore, depending on the topic. You may also find that other branches and related fields of marine biology can be equally or more interesting. Find out more about the details and features then decide which one will best suit your personal interests and needs. Here are some more tips.

About Marine Biology

The field of marine biology involves the study of aquatic organisms, the behavior and other interactions with the environment. It is considered one of the most diverse and interesting fields in oceanography. If you want to understand marine organisms and their different behaviors fully, you have to get a basic understanding of other disciplines and aspects of oceanography, like geological oceanography, chemical oceanography and physical oceanography. Biological oceanographers and marine biologists get to study these related fields during their careers to get a wider perspective during research.

Since there are several topics, marine researchers choose a specific interest and focus on it. Specializations can be founded on a specific organism, species, ecosystem or behavior technique. Marine biologists can select to review a certain species of fish or all kinds of fish that live in a given region.

Other Specializations

Most of this information comes straight from the Marine Biology pros. Careful reading to the end virtually guarantees that you’ll know what they know.

Marine biotechnology is a fast-emerging field that provides huge opportunities for marine biologists. The research shows a very wide array of opportunities and applications. A focus aspect involves the biomedical field, wherein scientists improve and test drugs, many that come from marine organisms. One type of an application of biotechnology research can be viewed in defense or industry, wherein researchers create non-toxic coatings that limit the build-up of organisms like zebra mussels and barnacles.

Molecular biology is another related aspect of specialization. Researchers will apply molecular techniques and approaches to different environments, in the deep sea and coastal ponds. They also apply these to different organisms, animals, plants and microscopic bacteria. Molecular biology can be used to identify the presence of a certain organism in a water sample via the use of molecular probes. When the organism is the same to other organisms or is microscopic, the data can be highly helpful.


Aquaculture is defined as the farming of shellfish, seaweeds and finfish. It is another field that is supported by molecular approaches and marine biotechnology. Aquaculture is quickly getting more attention since people are now looking for more fish and shellfish. Technological developments have also been made, making the approach more economically feasible. Economic value is increased as professionals discovered the way to extend the harvest and market season.

More Advances

Marine researchers are now looking for ways to provide drugs to affected populations of fishes raised in farms. The disease can be very detrimental for harvesting. Technology has allowed out fish tissue layers to be more permeable, thereby making the fish more receptive to antibiotic drugs and vaccines released into the water. As a result, healthier fishes can be raised in farms to provide for various populations.

Earning Money as a Marine Biologist

You may be surprised to know that marine biologists, and other careers related to the profession can earn a lot of money. You get the best of both worlds by having the opportunity to explore the deep waters and still get substantial salary. Learning more about the coverage of each profession and having an idea about how much to expect will help you decide better. Here are some guidelines.

Salary Overview

Being a marine biologist is already a dream job for several individuals since you get the opportunity to travel all over the world, study interesting aquatic plans and animals and support different conservation efforts. You do not have to worry about travel expenses, hotel accommodations and having to purchase expensive tools and equipment, since there are already plenty of facilities and laboratories available willing to provide for your every need. You can also receive grants and other financial opportunities, provided that your type of research is interesting enough to make developments in technology and history.

Asking Questions

There can be several questions asked by the average applicant. How much can I expect to earn per week or month? Will I be paid per expedition or project or by the hour? What determines the salary difference between job positions? Will experience affect the salary? How do salaries of marine biologists compare with marine service technicians salary? How soon can I expect a raise? How big a raise can I get in the first few years?

Determining Salary

Now that we’ve covered those aspects of Marine Biology, let’s turn to some of the other factors that need to be considered.

There can be several factors in determining a marine biologist’s salary such as location, type of industry, benefits, type of project, degree attained and level of experience. If you check the salaries according to state, you will find that Massachusetts and Washington individuals get the highest median salary.

Depending on Location

For those interested to work in sunny locations, you will find that San Diego and Miami offer the highest salaries. A marine biologist salary range can stay the same consistently during the first few years on the job. After about 10 years in the industry, you will observe the salaries tend to shoot up significantly. The salary of marine service technicians also tend to be lower compared to marine biologists. Marine service technicians can earn more than $20 per hour after working for 20 years.

Perks and Advantages

Some marine biologists may be hired on a project basis. Individuals invited into expeditions are usually very experienced and are paid higher than the rest of the group. Some marine biologists are invited because of their specific focus and thrust in terms of studying animal and plant life and the different ecosystems.

You can also get some added advantages that may not come in the form of money, such as getting free tickets or discounts to different locations all around the globe, getting access to restricted laboratories and other institutions and getting to meet people who may offer you grants and other means of support. You can also join different seminars and forums that only selected people can attend.

What is Marine Biology?

The only way to keep up with the latest about Marine Biology is to constantly stay on the lookout for new information. If you read everything you find about Marine Biology, it won’t take long for you to become an influential authority.

Several individuals have always dreamed of becoming a marine biologist, but not many is actually informed about the real extent and coverage of the practice. Marine biology is a branch of science that particularly deals with aquatic life. You have to understand the different features to determine if it is the right profession for your capabilities and interests.

Definition of the Term

Marine biology is described as the study of life forms that live in saltwater or usually ocean environment. Several life forms may be included in the studies such as the analysis of fish, plants, marine mammals and other microscopic organisms. Marine biology may also cover the entire ocean ecosystem, or a particular kind of life form, including its interactions with other living beings and the habitat.

Marine biology may also be described as studies in the field or the analysis of information collected from different ocean sites. It can be very comparative in nature, such as analyzing the same bacteria that live in different oceans. It can also be specific on the particular species.

As a Science

Marine biology is highly related to other kinds of science, like climatology since it has effects on life forms in the ocean, animal behavior and oceanography. Some marine biologists may focus on the biological nature of a given animal, while others focus more on the behavior of the animal. Several times, individuals refer to marine biology only as the study of marine mammals, such as dolphins, seals and whales.

How can you put a limit on learning more? The next section may contain that one little bit of wisdom that changes everything.

In reality, it represents a minor part of marine biology study. There are only limited marine mammals compared to large numbers of fish, plant and single-celled species in the ocean. Some less interesting species may have limited studies compared to the more glamorous marine mammals.

Grants and Activism

Marine biology sometimes can involve activism, since some scientists achieve high levels of education. Marine biology should be understood together with other existing sciences. Many individuals now aim to protect the ecosystems of the ocean, thus improving in their speaking and writing skills.

Several marine biologists can apply for grants. There are usually marine biology sites located in landlocked countries and states. Oceans and its many life forms have various effects on different areas. Prehistoric marine biology may also assess the tissues of extinct ocean life forms that still exist in areas where saltwater bodies are no longer found.

Knowing the Benefits

Marine biologists also continue to study to understand the nature and determine the many benefits of organisms in the ocean that can be highly helpful and supportive to human life. The different life forms in the ocean can have potential health advantages as well as provide the means to developing new medicines.

Some are even very helpful in preserving and protecting earthbound life forms. Marine biology has always fascinated people since several of the species in the ocean are still unknown. Some parts of the ocean remain inaccessible because of depth or temperature. Marine biologists are always open to the opportunity of becoming a part of new discoveries.

That’s the latest from the Marine Biology authorities. Once you’re familiar with these ideas, you’ll be ready to move to the next level.
