Write An Essay On The Evolution Of Sharks

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 important to our ecosystem and humans needs to protect sharks. The number of sharks have declined by 80% and the main reason is humans. Secondly sharks are important to our ecosystem to keep things balanced. Another reason sharks should be protected is because sharks can be used at a drug to treat human viruses. In conclusion this is why humans should stop the killing and start

One of the major problems is shark finning. Shark finning is the practice of removing the shark’s fins after it has been caught. They keep the fins and the body is usually thrown back into the sea, and usually the shark is still alive when this happens. When this is done sharks are not able to swim, and eventually the shark dies from suffocation, blood loss or being eaten another predator. The reason why the fins are kept are because shark fins are one of the most expensive food items in the world and can be worth more than over $400 per kilogram. One of the problems with finning and the selling shark fins is that it has caused a lot of declines in shark populations. Shark finning is unmonitored and unreported so the actual amount of finning is unknown. Finning is done at random and unbiased, they go after any species, sex or size of shark. Research has been done on some of the fins brought in by fisheries and it shows that even fins from great white sharks are appearing in shark fin

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

Shark finning is the process of cutting off the fins of a shark and discarding the body at sea (“Stop Shark Finning”, 2009). People catch sharks for its fins, meat, oil, skin and so on. Sharks fins are most commonly used in Asian cooking which is shark fin soup. According to Maddalena, Sommeran and Leander (2007), people have been demanding for shark fins dramatically recently, it is unclear how many sharks are caught annually but some of the conservationists estimate the number to be upwards of 100 million. Besides, shark conservationists are aware about the consequences of the high demand of shark fins, they advocate people to stop killing sharks and eating shark fins. Practice of shark finning is causing imbalance marine ecosystems and it

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 things that sharks are being killed for is sickening. So far, humans have decimated about 90 percent of the world’s shark populations for the sake of shark tooth jewelry and jaws that tourists buy in massive quantities, sharkskin accessories, phony medicines made from their cartilage, and a huge range of cosmetics, deodorants, moisturizers, sun tan lotions, and lip balms that use shark liver oil as a base because it makes our skin soft. (Check the ingredients of these items before you buy. If they contain “squalene” or “squalane,” leave them on the shelf.) (M. R., Ph. (2015, February 08). The Most Misunderstood Shark Fact Of All Time. From

Whenever you go to the Fish and Chips shop, have you heard about “Flake”? Flakes are a type of shark. They have been killed just for us to eat. The price of them are also increasing. At least 100 million sharks are killed every year. In Eastern parts of Asia, Sharks were being culled for shark fin soup. Dragging out the sharks out of the ocean and cutting off their fins and throwing their dead body back into the ocean is unacceptable. How would you feel if we were dragged out of our home by a random person, got our arm cut off and got put back into our home again? I’m sure that we would all be horrified and terrified by this. It is said that Shark Fin Soup costs around $100 per bowl of soup. There are also some countries that have completely banned shark culling. They are Israel, Ecuador, Mexico, Egypt, Indonesia, Fiji and so on. It is very unfortunate that Australia isn’t a part of this. Sharks also help with ecosystems.

Credibility statement: For most of my life I have been a shark enthusiast so shark finning is an issue I stay very informed on through various academic sources.

Whether it is the fining for fin soup or the desire to have a large shark jaw, sharks are being killed at alarming rates.

Shark finning is popular in asia. They cut the fin off of the shark, and then throw the shark back in the water. Since sharks are being killed for just the fin, there are bans against finning. People also started just killing them after the movie Jaws came out(8). It pictured a Great White shark attacking people viciously. It upset people because it was based on a true story, but in the actual occurrence it was a bull shark that attacked the people not the Great White(8). There are many shark sanctuaries set up in the ocean to protect them. They can go there and live without having to worry if they will get caught in a net or get their fins cut off. In many countries there are bans on Great White Shark products. There are many projects in effect for protecting Great White Sharks(Institution, Smithsonian). Great white sharks are illegal to hunt because they are endangered. They also have a short life span of about sixty years, but very few make it to even thirty. There are many signs that say the great white population is increasing slowly but steadily(Institution,

Donohue, Patrick and Log, Destin. “Sharks 101.” State and Regional Newspaper, 7 September. 2006. LexisNexis Academic. Web. 28 May. 2016.

Marine Biology funding increased and studies lead to the improvement of many oceanic devices, such as cages, shark repellant research, and unmanned camera platforms. The International Shark Attack File in Florida now records all "unprovoked" and "provoked" incidents. A chain of laws with the intention to protect sharks also emerged. Some laws include the banning of Great White hunting and the Shark Finning Prohibition Act of 2000.

Within 1996-2000, shark fin imports increased by 6%. To get the shark fins, men would catch sharks, cut off their fins, and then throw them back into the water. Are shark fin soup worth killing millions and millions of sharks? There are also many different uses for the different parts of the shark. For example, shark oil can be used for makeup and cosmetics, shark cartilage pills supposedly benefits our health and is old in health food stores, and shark steaks are sold all over the world. Although there are many economic benefits from shark finning, it can also threaten recreational fisheries, and other traditional ways of fishing.

Secondly, I will discuss about the famous shark fin soup. Lastly, I will discuss the possibilities that can happen if sharks are extinct
