Tiger Sharks
The tiger shark, Galeocerdo cuvier, is a large (up to
18ft) predator found in tropical and subtropical waters
world wide. Tiger sharks are one of the three main shark
species known to attack humans, and are responsible for most
shark attacks in Hawaii. Less than one shark attack occurs
per year on average in Hawaii (compared to an annual average
of 40 thousand drowning) and mosts attacks are non-fatal.
This attack rate is surprisingly low considering that
thousand of people swim, surf and dive in Hawaiian waters
every day. Despite these statistics, sharks attacks remain a
highly emotive topic in Hawaii. This reaction is
unsurprising in a state that is economically dependent on
tourism and recreational ocean use. Killing tiger sharks
contradicts traditional beliefs of native Hawaiians, who
consider these animals to be sacred ‘Auma kua’ or ancestor
spirits.

strips on its gray back, which pronounce in juveniles but
become pale or disappear in large adults. Its wide mouth,
broad nose, barrel chest, and the slenderness at the base of
its tail are distinctive. So, too are its heavily serrated,
cockscomb-shaped teeth. These, combined with is jaw

Every year, there are about 100 million Sharks killed, ultimately for its commercial success. Their fins are used as the main ingredient for a dish so-called Shark soup. However, many are unaware of the actual importance of Sharks' existence on Earth. They do a number of things to control and balance aquatic life down below, which in return affects how we live on the surface. Sharks have existed in our world for over 400 million years, if they were to suddenly disappear for industrial purposes, much problems will be encountered throughout the world. We must preserve the lives of Sharks, for many reasons most importantly that shark hunting is morally wrong, it may provide economic failure in a given time, and it may serve a critical unbalance of a healthy environmental state.
Flying Tigers is the name of a mercenary group of American pilots that helped defend China and the Burma Road from the bombing of the Japanese during World War II. The name of their planes was Tomahawks, but the Chinese called them Fei Hu for the sharks teeth painted on their planes. Flying Tigers were known as the American Volunteer Group of the Chinese Air Force. The Flying Tigers did not see combat until December 1941 when the Japanese started bombing China.
But occasionally the younger sharks are preyed on by bigger sharks that do not necessarily have to be Bull sharks they can be become prey to any larger species of shark and occasionally a crocodile. However there are parasites like Pandarus sinuatus, and Periscopus dentatus that use the surface of the shark’s skin and use it to survive (Curtis). Though that does not in anyway decrease or increase the economic uses for the bull shark, its effects on the environment, or level of danger to humans. In certain places around the world the amount of bull sharks is decreasing slightly, because sharks can be harvested to make fish food, for their meat, for oils, and their fins for shark fin soup, or in asia their skin can be used to make “good leather” (“Bullshark”; Curtis). Even though their numbers are thought to be decreasing according to the International Shark Attack Files, otherwise known as the ISAF, has reported that there have been at least 70 reported unprovoked attacks on humans of which 17 were fatal, but that is only the known number of the reported attacks by bull sharks there most likely have been many more attacks that went unreported (“Bullshark”; Curtis). They are known for being one of “the most dangerous sharks in the world” because they along side the tiger shark,and great white they are the most common sharks to attack a human

Manta rays, humpback whales, and dolphins are all gentle giants of the sea. These playful creatures enjoy leaping out of water, creating an unforgettable experience for the tourists of Hawaii (Saito). On the other hand, jellyfish and sharks cause fear in beachgoers because their attacks can lead to painful and life threatening injuries. Swimmers in Hawaii are often victimized by box jellyfish. The stings hurt quite a bit and cause an unpleasant burning sensation. Some people even suffer from a severe allergic reaction to the toxin and are hospitalized (“Dangers in Hawaii”). People may also be hospitalized from shark attacks. Three to four shark attacks occur each year in Hawaii, usually resulting in only the loss of an appendage. However, numerous shark sightings as close as twenty yards away from shore to as far as out at sea have been reported. Jan TenBruggencate’s article, "A Shark Bites off Left Arm of Teenage Kauai Surfer,” tells the story of thirteen-year-old Bethany Hamilton who fell victim to a shark attack in October of 2003. While surfing in Hawaii, a shark estimated to be 12 to 15 feet long bit into Bethany’s surfboard and took a majority of her left arm. Other major shark attacks include Joe Thomson, 1985, who lost his right forearm, Michael Coots, 1997, who lost the lower portion of his right leg, and Hokuanu Aki, 2002, who lost his left foot. Each victim had to fight with the shark to break free and were lucky to escape with minimal
The bull shark may be responsible for many shark attacks in the world but I believe that we have no right to kill them. Sharks are very important to animals food cycles and if the food cycles get messed up it can greatly effect the world. In fact, the bull shark is more vulnerable to human impact due to their ability to live in fresh and salt water but many sharks that are killed are for either shark fin soup or their liver oil. The sharks liver oil has many uses now but it started as a machine lubricant. Another way that sharks die is by recreational fishing. The sharks can get caught up in the fishermen's nets and eventually suffocate and die. As an environmental community, I feel like we need to inform people about shark habits and how to keep sharks safe. The water is their home and we are
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.
Sharks have several ways to dispatch their prey with surprise attacks, agility, and camouflaged sneak attacks. The shark’s dentition also tells the story of their diet as well as their method of attack. The Great White Shark, (Carcharodon carcharias), is the largest extant predatory shark on Earth and has large serrated teeth that tear through the flesh of its prey. Their teeth are 2.5-3 inches in height and have prominent serrations which allow them to tear large chunks out of prey including large fish, seals, sea lions, other sharks, carrion, dolphins, elephant seals, stingrays, and fish [8], [13]. These sharks hunt by swimming below the intended prey item and with a sudden burst of speed; they will attack with a large single bite and then swim off to allow the prey to bleed to death. These sharks are famous for breaching the water to grab seals and sea lions around the coast of South Africa in an area called Seal Island [7]. When the seals swim farther off from the island where the water is much deeper, the shark’s rate of a successful attack increase compared to the lowered success rate in shallower waters where the seals can easily outmaneuver them [7]. The bite force of the Great White measures around 4,000 pounds and is able to bite prey in half [10]. Great Whites
Everyone knows someone who is afraid of sharks. They might even advocate for the killing of sharks when they hurt someone or wonder why they exist on the first place. Every summer, shark attacks are a hot topic. There are news articles every summer about at least one person spotting a shark close to shore, and it seems like every other summer there is a blockbuster film about surviving a shark attack. Everyone knows that sharks are predators, but not everyone knows that sharks are on the decline. This is because of many reasons such fishing, and specific shark killings. Sharks are essential to our marine ecosystems, and the continued culling of them can cause the extinction of the species as well as a devastated ecosystem within our oceans.
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.
The great white shark is a very interesting animal. They get their names from their appearance. The great white shark is very big and has a blue stomach. The great white shark can be found in the pacific, Atlantic and Indian oceans. The number of great white sharks in the United States and in the world is unknown because it is too hard to keep track of all of them. They live in salt water and do not claim territories.
They are creatures with mysteries that aren’t yet explained most are but not all are explained. So let's see what is known that were mostly common.
#15 Island of The Blue Dolphins by Scott O’Dell is an example of the genre of historical fiction. The story is based upon a real story of a woman who lived alone on an island for eighteen years. The writing follows the years of this with its descriptions and true characteristics of this time period. The main character is a girl named Karana who lives on an island with her whole village including her brother. The story goes from the village being decimated by a battle, to everyone left leaving to find another home. Karana’s brother Ramo is not on the ship, but the captain will not wait for him. Karana jumps ship and stays on the island with her brother who is killed by feral dogs. Ironically she takes in a feral dog and trains him

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.
