White Sharks

Shark attacks still happen to this day. There’s nothing more terrifying than hearing a story in the news of a mighty, great white shark killing an innocent person. He mentions the backlash of Hollywood blockbusters such as “Jaws” and “Sharknado 3” that intensifies one’s fear. Sharks have evolved in our

Sharks have been creatures that can date back to over 450 billion years, and have survived through all disaster and still live on Earth today. This is a great feat for anything to stay in existence for that amount of time, and hopefully sharks can continue to live on this Earth and not go extinct. There are hundreds if not thousands of species of shark from when they first swam Earth’s oceans to when they continue to swim the same oceans. The study of sharks is a very interesting and extraordinary topic, being able to put together images of what sharks used to look like compared to sharks now is just amazing. In this vast amount of time sharks have spent on this Earth there has been many things that has changed, through evolution and adaptation. Through research and personal opinion I plan to show how sharks have evolved, what has changed through evolution and the history of

Sharks are vicious creatures and eat humans. Don’t go into the water if you see a shark nearby or they will come after you. These are a few of the many things you will hear from the television or even people you may know. Humans are not a part of the shark diet so it is highly unlikely that a shark would randomly go after a human. The media likes to make their shark stories more exciting by adding words like “aggressive” or “threatened.” There was a total of 4 deaths caused by sharks in 2014 which is a large contrast to the 11,417 sharks that are killed per hour by humans. sharks) need to be preserved and protected in order to preserve our oceans. Laws that are more strict should be implemented in order to achieve this goal.

Every Jaws fan knows the shark gets it in the end. What they do not know is that too many sharks have gotten it; and that has caused a rapid decline in the shark population over the past thirty years. Since the 1970's, sharks of the Atlantic and Gulf of Mexico shores have declined eighty-five percent. Sharks are vital animal to our world's ecosystem, and if the decline is not controlled; we could be facing devastating problems in years to come. Information has been obtained from two books: The Shark Almanac by Thomas B. Allen and Sharks, An Introduction for the Amateur Naturalist by Sanford A. Moss. Sources also include a number of online references, among them BBC News, ENS News, The New York Times, and two online scientific

Arising over 350 million years ago, the shark species has been labeled as a human devourer. Now, with the increase in human population, the demand for shark meat, fins, and cartilage are at an all time high; therefore, the existence of the shark is becoming a concern (Budker 1971). Individuals are conditioned to think of sharks as a negative aspect to the environment, which is prolonging the effort to save shark species from becoming extinct. With that in mind, some private as well as national organizations have accepted the challenge of educating and informing people about the existence of the shark specie and its importance to the sea.

The issue surrounding the Western Australian shark cull initiative will be the central topic of discussion in this critical essay. A rise in shark attacks in recent years has caused the Western Australian government to employ the Department Of Fisheries Western Australia to pursue a systematic and regulated cull of sharks. However the Greens – who are a political party and pressure group – are advocating for this cull to be stopped through lobbying.

The Shark’s place in the marine ecosystem is as a predator at the top of the food chain as there is no natural predator of sharks. Sharks are not very fastidious about what they eat but their diet generally consists of seal, crab, squid, lobster and fish. If sharks were to become extinct there would be an ecological cost. The marine life that is the shark’s food source would start to overpopulate with nothing to prey on it. One possible reason that sharks are coming closer to shores is that their natural food source is diminishing due to overfishing by humans. To stop sharks from being too near to popular swimming locations, fishermen need to expand or change their hunting areas.

Hyndes has supported his contention by offering suggestions to shark culling at the conclusion of his article. He states that we should be looking at ways to reduce our encounters with these “predators” as us humans are the people who continue to invade their habitat. Tracking systems is also another suggestion that Hyndes has offered in his article, as well as electronic devices and wetsuits. He hopes to convince the audience that we all need to be placing more effort and more funds into such an important issue by testing and develop these devices so that we can either deter sharks from entering our populated beaches or reduce our encounters with them. Hyndes hopes to emphasise that there are other solutions rather than culling these precious species.

Sea Shepherd Conservation Society’s article “The Brutal Business of Shark Finning” reminds us that sharks play a key role in the ocean as both predators and scavengers.

The ocean is one of the most mysterious places on earth. So much of it is still unknown that the National Oceanic and Atmospheric Administration predicts that almost 97 percent is untouched. The fear of the ocean heightened following the premiere of the cult classic movie "Jaws" in 1975. The internationally recognizable theme music still subconsciously haunts beachgoers, even two generations following its release. The franchise "perpetuated the myths about sharks as man-eaters and bloodthirsty killers " said George Burgess, a shark biologist at the University of Florida in Gainesville.

Advancements in Marine Science and Technology are the main reasons why, more information is coming to light about these sharks migration patterns along the East Coast of the United States. Stated by Emily Tripp in her article Study uncovers great hammerhead shark migration (2011) “Using satellite tag technology, the research team was able to track one of these nomadic sharks for 62 days to discover its 1,200 kilometer (745 mile) journey from the coast of South Florida to the middle of the Atlantic off the coast of New Jersey.” (Para. 2) Satellite Technology is important to finding out the migration patterns of these sharks. This technology allows us to see the bigger picture and patterns the sharks follow under the waves. To get the Satellite

Recent studies from the article “Hammerhead shark migration gives new hope for conservation” discusses how these hammerhead sharks have been listed onto the IUCN (International Union for the Conservation of Nature) since 2007, also having certain regulation about international trade threatening species going extinct. Dr. Tristian Guthridge explains the benefits of understanding the shark’s behavior and more research of where these sharks are migrating, and possibly manage the time of fishing in the areas to eliminate human and shark altercations. With the wide spread of ocean water it can be difficult to study the traveling of sharks; however, the research group was able to tag the sharks “with both acoustic and satellite tag, and use photo identification and laser photogrammetry” (Charlie Huveneers).

The theory is that rouge sharks are sharks that have chosen to prey and attack humans, and some believe they have developed a ‘taste for human flesh’. Great White Sharks are highly efficient predators and are known as apex predators, they top the marine food chain and are extremely dominant specie of sharks. This essay discuss the question, should rouge sharks be killed or conserved? The Great White Sharks population was threatened in the 1970’s and 80’s from overfishing, this caused a global concern which led to Great White Sharks are protected under the Federal Environment Protection and Biodiversity Conservation Act since 1999.

Did you know that only four out of the 400 species of sharks attack humans? Sharks benefit both humans and other aquatic creatures. This is why sharks need to be protected and tracked. Sharks aren't really the demonized creatures we all think they are. To begin with, there are only 400 species of sharks, only four attack and the blue sharks are not one of them.

Sharks have always been alpha predators of the ocean and they are able to use the scent of blood to find their prey as well as make animals cower in front of them including humans. The portrayal of of sharks through the media and movies have always made sharks seem like they are violent and scary creatures that should be fears and killed off. However, this portrayal of sharks is not true and it helps unjustly distort the truth of sharks and how they really are. The fact shark attacks are a huge media sensation when they occur such as the example of the eighteen year old kid that was photographing a shark and was attacked by a shark. However, modern evidence goes against all of the previous assumptions of sharks and actually make them out to be a more peaceful species.
