Shark Attacks
The serious attacks are mainly by four species. The Bull shark. the Tiger, the Great White and the Oceanic Whitetip shark. The Grey Nurse (Sand Tiger) and the Bronze Whaler have for many years been blamed for many attacks but it seems nearly all were mistaken identity. The Grey Nurse is now protected in most States in Australia.
The Great White is the largest and has a high percentage of fatal attacks. The Bull shark is responsible for a lot of attacks on swimmers and people in shallow water. From reports it seems a lot of these attacks were only one bite but a large percentage of the victims died of blood loss and shock. It is likely to be the worlds number one killer shark on swimmers. I have heard of a lot of encounters

Many of these fatal attacks have occurred in South Australia in areas well known for Great Whites. Abalone divers nearly always work in areas where seals are present and the water is cool. This is ideal for attracting the Great White. Add to this the fact that they spend an enormous time in the water and it is a recipe for disaster. It was noticed in California USA, that Abalone divers were only attacked north of Point Conception. It was later discovered that the law in North California did not allow abalone divers to use scuba equipment, which meant they spent much more time at the surface. In southern California scuba was permitted! Spearfishing has two major negative factors. The first is that they are working on the surface as it is illegal to spearfish with scuba equipment. It is well known that the Great White usually attacks on, or very close to the surface, coming up from below its intended prey. The second problem with spearfishing is obviously the dead fish and blood attracting sharks. Even usually non-aggressive species of sharks will attack a spearfisherman if he has killed a fish. The book 'Shark Attacks' by Alex MacCormick (1996) also wrote of this incident. It seems this information was taken from 'The Adelaide Advertiser' newspaper in 1962. The book wrote the …show more content…
Incidentally I have never stopped diving and still enjoy the activity. Regards Brian Kennington

"You mention how unreliable even the official stories about Shark attacks are. Yes indeed. In the book Shark Attack by Alex MacCormick, they list an "unprovoked" shark attack by a Sand Tiger off Cocodrie Louisiana. They say the guy was just sitting on a beam and CHOMP a sand tiger grabbed both his legs and tried to twist them off.
I know the divers involved. They're featured in my book. One Diver had SPEARED the shark (for a Bar-B-Que) and it was twisting around in the bottom murk with mouth agape and grabbed the other diver's leg. Simple as that. They chuckled about it. "Those newspapers believe anything". Anyway that was ten years ago."

Shark nets have been implemented in locations across the world in response to shark sightings and attacks. Nets are submerged beneath the surface of the water, roughly 200 metres from the shoreline. The meshing is designed to be large to capture sharks, leaving them to struggle before eventually drowning under the weight of their own body. The meshing allows small fish to pass through, however captures larger fish and marine species. Shark nets provide no discrimination between common, vulnerable and endangered species, resulting in a high mortality rate for a variety of marine wildlife.
The Kingdom, Phylum, Class, Order, Family, Genus and species for the Bull Shark are as follows: Animalia, Chordata, Chondrichthyes, Carcharhiniformes, Carcharhinidae leucas (Simpfender & Burgess). The taxonomy of every living thing is different, so the classification of the Bull Shark is the one way worldwide to know exactly what animal is being referred to because one animal may have many different common names. Carcharhinus leucas is referred to by many different common names around the world for example the spanish it Tiburon Sarda, the french call it Requin Bouledogue, in Africa they refer to it as Van Rooyen's Shark, in Australia it is referred to as the Swan River Whaler, and that is only a few of the Bull Sharks many common names (Curtis).
The Carcharhinus leucas commonly called the "bull shark" is a very unique shark. The bull shark can live in both salt water and fresh water but is commonly found along the Mississippi River and around Nicaragua. The bull sharks has a very blunt rounded nose giving it a bullish type of appearance thus giving it the name bull shark. The sharks are a dark black to a light grey with a white underbelly. Bull sharks can grow to be about 350 cm long and weigh around 230 kilograms. Bull sharks also tend to have smaller eyes compared to many other sharks which indicates that the bull sharks have limited vision. The bull sharks have triangular teeth like the great white shark (one of the bull sharks cousins). The bulls teeth are heavily serrated and are about 1.5 inches long which makes it easy to tear apart the flesh of their prey.
Sharks have also been subjected to medical research, games and competitions, jewellery, souvenirs and cosmetics. We need to take into consideration that sharks play a vital role in the natural world that we live in. it is imperative that we look after these majestic creatures and ensure they remain protected. We need to be aware of the dangers of sharks, swim in protected areas where there are shark nets, and do not swim after dark in the sea (especially not alone) as the sea is the sharks home. Humans should also be wearing wet suits as protection in the ocean. The sea is where they live, they swim freely and they eat – they do not particularly target humans but rather prey on food that is available to them in their habitat.
Have you ever wondered what the scariest shark is? I know i have. Well the scariest looking shark i know is the basking shark. The basking shark has a huge mouth and will eat you if you mess with it. These animals don't have a regular nutrient cycle they just eat what they really can. There natural biome is .The habitat
When most people hear the word "shark", the image of a vicious killing machine pops into their head. They picture something out of the movie Jaws, where a massive Great White shark terrorizes an entire beach and eats dozens of people. However, this fictional story is nothing more than Hollywood entertainment. In the real world, the tables are turned. Humans are the ones who kill sharks, and not just by the dozens. It has been estimated that over 100 million sharks are killed every year by humans (http://www.iflscience.com). Some estimates claim that the actual number of sharks killed every year could be as high as 273 million (http://www.iflscience.com). In this research paper, I will inform you of the many ways that sharks are being killed,
In 2015 only 59 shark attacks have occurred around the world compared to the millions of sharks killed by humans every year. Due to these accidental shark attacks people tend to think that sharks, especially Great Whites are evil creatures with malice intentions when attacks do occur; but, on the contrary that is wrong. Sharks are not the only beautiful and unique creatures in the ocean, they also play a vital role in our ecosystem; however, due to human interference they might not be around much longer, through awareness sharks can be protected from endangerment.
Bryant, Charles “How many sharks are killed recreationally each year -- and why?” AnimalPlanet 9th March 2014 http://www.animalplanet.com/fish/shark-fishing.htm
“The United States averages just 16 shark attacks each year and slightly less than one shark-attack fatality every two years. Meanwhile, in the Coastal U.S. states alone, lightning kills more than 41 people each year” (Handwerk). Not man people can say that they have been attacked by a shark, or even know someone who has. The story is not the same for Bethany Hamilton. She is a shark attack survivor. When the odds of her surfing again were against her, she proved them wrong.
Sharon Guynup says, "Most sharks are harmless,” (“What Do You Know About Sharks?” 872). Over 300 species of sharks are harmless to humans, and the ones that are harmful do not attack often. Peter Benchley states, "Only four [sharks] attack human beings with any frequency," (“Great White Sharks” 890). When people swim, they should not be afraid of being attacked by a shark, especially if the area is not known for shark attacks.
Most people think that sharks are large, fast-swimmers, and savage predators. This is true of some species and groups should be interested of the appealing aspects of biology found within it: all sharks have an excellent sense of smell; some can detect electrical discharges; some sharks give birth to one of the
Although sharks belong to the class Chondrichtyes, there are many different types. Sharks arose about 350 million years ago and have remained virtually unchanged for the past 70 million years and still comprise a dominant group. It is thought that sharks almost certainly evolved from placoderms, a group of primitive jawed fishes. It took a long series of successful and unsuccessful mutations with fin, jaw positions etc to give us all the different designs of sharks around today. When asked to draw a shark, most people would draw a shape along the lines of the whaler shark family, tigers or a mackeral shark such as a porbeagle. However many people do not realize the sheer diversity in the shape of sharks, or that rays are really sharks. Seldom does such an animal inspire such a variety of emotions reflecting a mixture of fascination, awe and fear. Sharks have occasionally exacted a terrible price from humans who have trespassed on their territory. No better understood than the ocean that they inhabit, these creatures should be regarded in the same way as lions, tigers, and bears: as dangerous, predatory but nonetheless magnificent animals. Different Types of Sharks Living sharks are divided into eight major orders, each easily recognizable by certain external characteristics. Each order contains one or more smaller groups, or families. In all there are 30 families of sharks and they contain the 350 or more different kinds or species of sharks. The eight major orders of sharks include the Squantiformes, Pristiophormes, Squaliformes, Hexanchiformes, Carcharhiniformes, Lamniformes, Orectolobiformes, and the Heterodotiformes.
Thesis: Sharks should be conserved because they are an important part of the ocean, attacks are often incidental, and human behavior influences the behavior of sharks.
You are smelling the salty water around you and you suddenly feel something pass your leg.It`s a bull shark waiting to devour you.These species and the hammerhead are the two species of shark that you would not want to be noticed by.Both species are extremely dangerous and deadly.Bull and hammerhead sharks have many similarities and differences.The differences between these two species concerning apperance,diet,size and other important factors of the species` lives are important to know in case of close encounter and need of survival.It is important to know what they look like so it is easier to identify them and to know their special abilities so they will be easier to evade.Hammerhead sharks and bull sharks are very aggressive towards their prey and take over most oceans.These species are very important because if you want to study them for research,then you should know their normal personality traits for easier behavioral comparisons.
...k. Scared and moving back a little more, the shark was in a freeze position no flipping or wobbling, the only thing that was making a move was his gills. Wanting to know more I asked what kind of shark it is and was told that it’s a Caribbean Reef Shark. After the adult left all the children there, we start to poke it with a stick and was touching it with our hands and feet to feel the skin, which felt rough like I was touching sandpaper. When the kids were poking the reef with the stick I thought it would react in a very aggressive way but that wasn’t the case, it was still calm until they start getting aggressive their self. I sacred cause that’s when the reef begun to start snapping at every movement that was making. It was getting too much for me to take especially since it was going out of control, so I left and have no clue as to what happen to the Reef Shark.
