There are several aspects of marine biology. Some of these tend to be very boring and take several trials and repetitions before you can come up with a definite conclusion or results. If you, however, study mammals instead, you may realize that research tends to become more interesting and easier, since these animals react very quickly. You will have more data to gather and observe, thereby providing you the opportunity to enhance your skills.

The 3 Orders

Marine mammals are generally grouped into 3 orders. The order Cetacea includes dolphins, whales and porpoises. The order Pinnipedia involves walruses, seals and sea lions. The order Sirenia includes dugongs and manatees.

The whole lifecycle of the order Cetacea is aquatic. There are a couple of sub-orders founded on the feeding mechanism, namely Odonticeti and Mysticeti. The order Pinnipedia involves part of their lifecycle being terrestrial. The word Pinnipedia means “feather-footed” since the animals possess 4 webbed fins. These can be found in all oceans, but most reside at high latitudes, traveling usually in herds and carrying out very long migrations. The order Sirenia usually spends their whole lifecycle in the water. These are the only aquatic animals that eat plants mainly.

The Suborders of Cetacea

The sub-order Mysticeti includes baleen whales and blue whales. These animals use baleens or brush-like triangular continuously renewing plates that hang from the roof of the mouth, with 480 plates on each jaw side. The plates filter zooplankton, squid and small fish, with the tongue moving the food into the throat.

Right whales are skim feeders, grey whales feed via a suction mechanism on animals living on the bottom of the ocean and minke whales feed by gulping and lunging. Different whales use various approaches to eat successfully. The sub-order odonticeti includes mammals that have their first teeth remain until they die. These grasp and swallow whole prey. A good example is the killer whale.

About the Pinnipeds

Pinnipeds have a low SA/V ratio and develop insulation via their hair and blubber. Fur seals can have so many hair belonging to either underfur fibers and guard hairs. These all moult, especially during the summer after breeding period, while others just remain out of the water until complete. Pinnipeds exhale before deep dives and have high myoglobin and hemoglobin concentrations. These animals feed usually on fish and squid. The walrus will use their tusks to dig for animals living on the bottom.

The Sirenia

Sirenians are distributed widely but are usually caught for their hides, meat and oil. They are particularly prone because they are placid and slow moving. Danger comes mainly from powerboats at present and their loss of habitat. These animals are very social but now prefer to go in family groups or alone.

Dugongs are usually found in the Pacific and Indian Ocean. Manatees can be found in Atlantic coastal waters. Sireneans inhale before they dive into the water, just like whales. These can dive for 10 to 20 minutes. Bristles can detect food to help themselves tide over the lean months.

Before you become a marine biologist, you need to know the requirements and tools that will help you land a stable and interesting job. The subject is so diverse, which is why you have to spend some time contemplating on which subjects to take, as well as the inclusions of each related job. You may realize that you want to work in a related profession. Here are some of the common questions asked by individuals.

What should you major in if you want to work with aquatic mammals?

Very few individuals choose to specialize in marine mammals even though the subject is very interesting. Students are recommended to take up courses in organismal biology like fish biology, marine mammals, vertebrate biology and invertebrate biology. They should also take up courses in aquaculture and aquatic animal illnesses to plan for aquarium work in the future. Students who aim to work with marine mammals must take up courses in animal behavior, as well as other courses on aquatic mammals if these are present. Volunteers can work at an aquarium or stranding program is ideally needed for entrance into the competitive field. You can visit different marine mammalogy web sites online for more information.

What should you take if you want to focus on sharks and fishes?

If you want to study sharks or fishes, you have to specialize in the subfield within the fields of marine biology and ichthyology. Students must major in Marine Biology or Biological Sciences and take up courses in Fish Biology, Vertebrate Biology, Ichthyology and other specialized courses, as much as they are available.

If you want to go to Vet School, Medical School or Dental School, can you take up Marine Biology as a major?

You can still take up marine biology as a major even if you want to take up another course or school in the future. BS in Marine Biology is just the same is BS Biological Science. It includes courses that are needed for entrance to Vet, Medical or Dental School. Students are recommended to take up different courses aside from the others to satisfy the major in marine biology, making the completion of the course more challenging with added studies.

Do I have to meet my faculty advisor every semester?

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

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

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.
