Dusky Shark Essay

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.

Overfishing is a death sentence to the world’s oceans. As technology continues to improve a great deal of fish can be caught quicker; but at what cost? The effects of overfishing can lead to the extinction of not just the animals being fished, but also the predators that rely on fish to eat. Ninety percent of the ocean’s largest animals have been wiped out due to overfishing (“Overfishing- A Global Disaster”, 2011). National Geographic cites the academic journal Science (2006) that predicts by 2048, all fisheries will collapse due to lack of ocean wildlife. Fish are not the only animal caught in the nets used by fishing vessels. Often animals such as dolphins, sharks, turtles, and seabirds are

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.

Picture the beach, the golden sand and aqua water, the warm bright sun in the background, Imagine what is under the water, the aqua clear waters and the little fishes, but instead the ocean is full of nets capturing these harmless sharks. This is redicious to capture and kill these native Australian sharks. Shark culling has become the new issue for Australian media. Shark culling is not the answer for safer oceans.

There would be too much damage to the nervous and muscle system to regain use of the arm fully; the muscle and nervous system would not be able to send messages to the brain in order to control the arm.

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.

The issue of shark culling has recently surfaced in the media. The article ‘Proof still required that shark culling works’, written by Glenn Hyndes and published on abc.com, addresses the fact that there is no evidence that shark culling is beneficial for the public, yet the law has been used by the Western Australian Government. This article was written on December 12th 2013, when shark culling was discussed in the media, has a very passionate, logical and concerned tone towards the topic. Hyndes has written this article for an audience of people who think sharks are a danger, people who want to protect sharks and the Western Australian Government.

The cause of this debate comes with the return of White Sharks to the area. Over the past few years, there has been an increase of this apex predator to our coasts like never before seen, most notably since Labor Day weekend in 2009. Five sharks had been tagged by a marine biologist, Greg Skomal, and have been closely tracked and documented since. Skomal is a key player in this research as project leader

Strategy is not easily defined and furthermore the term is not exclusively related to just the business world. We can confidently say strategy is key to survival, not only in business but also in the animal kingdom. All animals under go a process of constant change in their physical appearance and in their behaviour. These changes take place over millions of years and the species that survive, do so because throughout their evolution they have perfected certain strategies that have enabled them to develop more successfully in the environment they inhabit. One such case of this successful development is the great hammerhead shark.

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.

Beginning with the simplest one-celled organism, an extraordinary animal rose in the murky waters entitled to a non-comparable killing-eating machine. This organism has become nature’s most genuine and most successful creature that it has remained unchanged for over 250 million years. Nature finally invented the perfect king of the sea. This animal has given the sea it’s “living” adjective; in turn, it was entitled—the “great white shark.”

Cetacean bycatch is an ongoing problem in the oceans of the world. Cetaceans are defined as whales, dolphins and porpoises(CBRC 1). Bycatch is “marine mammals that are “captured” but discarded”(Read 2). This happens when fishing industries are fishing for a certain type of marine animal and other marine animals are caught accidentally along with the intended catch. Many times, this leads to the death of the animal that was not meant to be caught, and the animal is tossed back into the ocean. This happens with all kinds of marine life, and it has caused the depletion of many different species. However, this is specifically bad for cetaceans, such as dolphins and whales, because they have such a long lifespan(Brown 2). They also take a very long time to mature(Brown 2). These factors make catching these animals very detrimental to the species as a whole because it takes longer for them to reach an age where they can reproduce(Brown 2). The population of many cetaceans have decreased exponentially. When there is someone watching the nets that cetaceans are accidentally caught in, many times they can be saved. However, there are only select few types of fishing methods that do this, and they are not of the prevalent fishing methods that produce cetacean bycatch. This is a problem because there is a connection between most living animals. If a certain part of the connection is eliminated, it will all fall apart. For example, the relationship between

Sharks are one of the most feared carnivores in the sea. There are 365 species of of sharks in the sea as we know today. All sharks are carnivores. Most of them eat live fish, including other sharks. A shark's most common natural enemy is an another shark. Most sharks eat their prey whole, or they tear off large chunks of the bodies. Some sharks crush their prey. Others take out small pieces off flesh from large fish. Sharks also feed on dead or dying animals. Sharks have the reputation of attacking human beings. But less than 100 shark attacks a year are reported throughout the world. Sharks are most common in warm seas and oceans. Whale sharks, are the largest shark known to man. Sharks are classified in the order

b) Sharks try so hard to become unhooked that they end up suffocating themselves. Most of time the long lining is not meant to catch sharks but other species, and so then the Sharks are just thrown back to ocean as a waste. This process is call bycatch.
