Thesis Statement On Sea Cucumbers

I’ve always had a keen interest in science. When I was younger, I viewed a dolphin show online. I was instantly fanisnated and later I was informed that the trainers were special marine biologists. The idea of becoming a marine biologist is still a dominate career choice for me. Last year, I was incredibly curious with the aspects that a marine biologist has to undertake that I researched the career path as part of my PLP. This only ignited my interest even further and when I was invited to attend the Flinders University I particularly focused on the marine biology and biology lectures.

My interest in Marine Biology started when I was 8 years at Sea World. I've had a passion with it ever since, watching Shark week on tv and the Deep blue shows. I’m preparing now by taking Biology and Chemistry, I am watching educational shows about the ocean in hopes of discovering more and fulfilling my goals. I want to explore the ocean and discover new sea life. The ocean is very interesting and big just waiting to be explored and discovered. I hope to major in Marine Biology.

Coral reefs are the most biodiverse ecosystem on the planet. There are more than 25,000 known species of organisms and countless others that have yet to be identified (Helvarg, 2000). Reefs thrive on the shallow edge of tropical seas, most often on the eastern edge of continents along warm water currents that brush the coasts. Reefs cannot live in cold waters and are limited by ocean depth and available sunlight. Coral is the foundation of the reef community, providing a three-dimensional structure where thousands of species of vertebrates and invertebrates live and feed. Some species of coral are hard, while others soft. Some are branched, yet others are compact and rounded. Coral is made up of large

The dream of having majored in marine biology is one thing, but to get to have a marine biology degree is a fifth grader’s dream come true. The environment is heading in a rough direction. For example, ocean acidification is already a problem. The decrease in pH of our ocean acidity is causing coral reefs to die out—which houses thousands of organisms’ homes and food sources. Due to the contaminants, we release into the natural environment, we are slowly losing ecosystems every day. Therefore, I want to be the researcher to help save the oceanic life from these horrible conditions. Also, the career of marine biology can take a person anywhere, from the coasts of the Bahamas all the way to the depths of the Arctic Ocean. This provides the advantage

Introduction: Almost every place on Earth, from the surface of your skin to the bottom of the ocean, is teeming with living things. To keep track of the vast diversity of life, biologists historically named and classified organisms according to their appearance. The system of categorizing organisms is

Although there can be certain cons to pursuing marine biology as a profession, there are an abundant amount of pros to living this life. In addition to learning about marine creatures, marine biologists also help develop medicines and find different cures for sicknesses ("What is Marine Biology?”). Marine biologists get to see amazing aquatic places and animals that are very astounding and beautiful. I have wanted to be a marine biologist since I was five years old I never saw myself being anything other then that. After reading five articles and writing this essay, I cannot wait to go to college and become a marine biologist. The ocean takes up 96.5% of the surface of the earth. There are numerous amounts of mysteries that make up the deep-sea and without the help of marine biologists they would all be

Echinoderms such as starfish, sea cucumbers, and urchins are identified by their symmetry and central mouth. This species is found decorating the coral reefs by their variety of color and sizes. Because some of these animals like to burrow in the sand, they can supply oxygen to some of the depths in the ocean. Echinoderms are a staple food in many sea animals diet.

When choosing a level of identification, taxonomic sufficiency is an important concept to consider. Benthos must be identified to a level that will reliably asses biological condition and recognize ecological patterns. Finding the balance between getting an accurate representation of a biological community and the accuracy of identifications involves consideration of time and financial constraints as well as the expertise required.

For millennia, terrestrial plant matter, seeds, and driftwood have travelled across the open oceans with the help of surface currents. Even floating islands, also known as tussocks, floatons, or sudds are common in many Florida lakes and across the world (Mallison, C.T., 2001). These islands have been known to carry exotic plants and vertebrate animals. Floating islands promote trans-ocean dispersal of marine and terrestrial organisms. This increases biodiversity and helps new barren islands thrive. However, in the last five decades, with the growing number of plastics in the marine environment, the dispersal and occurrence of these organisms has increased exceedingly (Gregory, R.M., 2009). This paves the way for invasions by alien and even aggressive invasive species to establish themselves in new ecosystems beyond their native range. A survey done in 2009 reported that over 150 marine species have established themselves due to marine debris stranded on the shores of northern New Zealand. Most of these organisms were identified as crustaceans. Four of those organisms discovered are featured in figure 3. Specimen A shows various crustaceans on unknown plastic, specimen B depicts warm water Indo-Pacific oysters growing on nylon rope, specimen C depicts crustaceans growing on a plastic pellet, and specimen D depicts a bryozoan colony attached

Marine Biology is a fascinating field to learn about, but to make a career in it you should consider three things: the job itself, requirements, and why you may be interested in this career. Many of these Questions can be answered by simply studying the career further and talking to a person who has a Marine biology vocation. But as we dive into the field and its unique qualities we must be aware to look at all the facts.

After many family vacations to the beach, where I experienced the ocean first-hand and most recently, a summer camp through MOTE Aquarium, I now have a new goal, which is to become a marine biologist. The majesty of the ocean, the ocean life, and the ecosystem are something that I have always been intrigued by and now plan to make it a career. I realize that becoming a marine biologist is not going to be an easy task to accomplish, but I am prepared for the hard work and dedication it will take to reach my long-term goals. I am excited about not only the classroom portion of marine biology, but equally excited to get in the field and experience hands-on learning and research.

This identification database created by Herbert will hopefully in the future hold the DNA sequence of every living specimen that resides in the ocean. While that is the ideal situation, it is going to take quite some time to complete such a large and strenuous task. Every living organism has several stages of life and their DNA sequence can vary at each stage of life, so scientists have to come up with a way to group animals that have similar DNA sequences. It is still in the early stages so there are kinks to be fixed but scientists believe that can create some sort of system that if two DNA’s have a certain percentage-matching rate, which could mean they belong to the same species. The identification of another species in the same family could mean that the organism has learned how to adapt to the environment and it has grown strong enough where it can now survive natural selection. Also, very few ocean organisms undergo recombination, which enables scientists to keep great track of species for an extended period of time. There are so many organisms in the ocean reefs that have yet to be discovered or even thought about and with the DNA sampling it will bring to light so many new

The coral reef surveyors were instructed to find the best sites that they believed had the most living coral and were thought to be least affected by human activities. This would allow Hodgson to determine if human activities were having an appreciable effect on the supposed pristine coral reefs, which were distant from urban centers. The invertebrate survey was undertaken at two depth intervals of 3m and 10m. Four 0.5 m wide by 20 m long belts were placed on the coral reef. Over a period of 3-5 minutes the observers counted the number of invertebrates found on the belts. The coral survey was performed, by placing four 20 m long belts on the coral substrate. At 0.5 m intervals the substrate on which the belts were lying was examined and recorded.

Possible careers for those intrigues in marine biology include a teaching position, being a research scientist, hydrologist,

     Coral reefs are one of the oldest types of living systems on earth, and certainly one of the most spectacular (Goreau, 1987). They are massive underwater structures formed by the limestone skeletons of tiny invertebrate animals. Reefs house a greater diversity of body forms, chemistry, and animal phyla (thirty-two compared to the eight that inhabit the most biodiversity ecosystems on land). Phyla comprise the second largest category of living things, after kingdoms.
