Marine biology is a branch of biology. It is closely linked to oceanography, especially biological oceanography, and may be regarded as a sub-field of marine science. It also encompasses many ideas from ecology.
What are the three categories of marine life?
Three main groups of ocean life are plankton, nekton, and benthos. Plankton float in the water. Nekton swim through the water. Benthos live on the ocean floor.
What are the 4 branches of marine biology?
It’s typically divided into four sub-disciplines: physical oceanography (the study of waves, currents, tides and ocean energy); geological oceanography (the study of the sediments, rocks and structure of the seafloor and coastal margins); chemical oceanography (the study of the composition and properties of seawater …
What are 5 things marine biologist do?
EnvironmentalScience.org says that the duties for marine biologists include, “conducting species inventories, testing and monitoring sea creatures exposed to pollutants, collecting and testing ocean samples, preserving specimens and samples of unknown species and diseases, and mapping the distribution, ranges, or …
What do most marine biologists major in?
The major you need to be a marine biologist can be any of the following: biology, zoology, animal science, conservation biology, environmental policy and management, hydrology, oceanography, marine biology, and more life science-related disciplines.
Is marine biology hard?
But let us tell you now, that “getting into” marine biology is much the same as every other career – it requires hard work, commitment and the knowledge that you are entering a competitive field.
How are marine animals classified?
Marine mammals are classified into four different taxonomic groups: cetaceans (whales, dolphins, and porpoises), pinnipeds (seals, sea lions, and walruses), sirenians (manatees and dugongs), and marine fissipeds (polar bears and sea otters).

What are the major specialties within marine science?
Some of the specialties can include marine physics, chemical oceanography, marine meteorology, geological oceanography, biological oceanography and others.
What do you study in marine biology?
Students take courses in biostatistics, oceanography, and marine chemistry, ecosystems, and geology. They may then choose electives in their area of interest. Students may choose to focus on the ecology of a specific marine area, or they may study a type of marine organism, like corals, fish, mammals, or plankton.
Do marine biologists have to swim?
Many roles are lab or office based and field work frequently involves surveys which are boat based or on the shoreline. You actually don’t even need to know how to swim!
Do marine biologists go in the ocean?
A marine biologist’s job may involve fieldwork, either in or on the ocean, a salt marsh, a beach, or an estuary, again, depending on their specialty. Marine biologists may work on a boat, scuba dive, use a submersible vessel, or study marine life from shore.
What is a marine biologist called?
Marine biology is an umbrella term and there are many specialisations within the domain, such as fish biologist, microbiologist or marine mammologist.
Does marine biology require math?
Nearly all college curricula for marine biology majors require at least Calculus 1, and some require Calculus 2 as well. Most colleges first require the successful completion of algebra, trigonometry, and sometimes, elementary analysis — also known as precalculus — in order to enroll in calculus.
What is the best job for marine biology?
- Natural Resource Technician.
- Marine Archaeology.
- Stranding Response.

- Environmental Planner.
- Research Technician.
- Microbiologist. Microbiologists study microorganisms such as bacteria, viruses, algae, and fungi as well as some types of parasites.
How often do marine biologists travel?
Do you travel often? Yes I travel very often. At this point in my career, I travel almost every month for a meeting, conference, or some field work. My work takes me wonderful places all over the world but it requires being away from home frequently, and sometimes for long periods.
Is it worth being a marine biologist?
Marine Biology is a great field of study. It provides a wide range of career opportunities. Marine biologists can find jobs in a variety of fields. They can work at colleges and universities as researchers, teachers, or administrators.

Is marine biology stressful?
3) There is a high level of stress in being a marine biologist. In research, a lot of things turn out in ways you least expected and if you have to quickly make adjustments. There is quite a bit of competition, as well.
What sea animal is not a fish?
Sea stars, commonly called, “starfish,” are not fish. There are approximately 2,000 species of sea star, all of which live in marine waters. Sea stars live underwater, but that is where their resemblance to fish ends. They do not have gills, scales, or fins. Sea stars live only in saltwater.
What ocean animals are not fish?
Mammals. Whales, dolphins, porpoises, walruses, manatees, dugongs, seals, and sea otters are all mammals that live in the ocean. Some, like seals and sea otters, can also live on land, but they spend most of their time underwater.
Why is 95 of the ocean unexplored?
“The intense pressures in the deep ocean make it an extremely difficult environment to explore.” Although you don’t notice it, the pressure of the air pushing down on your body at sea level is about 15 pounds per square inch. If you went up into space, above the Earth’s atmosphere, the pressure would decrease to zero.
How much ocean is unexplored?
More than eighty percent of our ocean is unmapped, unobserved, and unexplored.
