Great white sharks are the main predators in the ocean. The only things that are responsible for the deaths of sharks are Age, Health, Humans and other sharks. Humans are responsible for 70% of deaths for great white sharks. Today there are more than 440 known species of sharks. Great whites only have 2-12 babies at one time unlike others who have hundreds.
One of the largest sharks in the world is the tiger shark. The tiger shark’s scientific name is Galeocerdo Cuvier. They are strong, but slow moving, relatively sluggish sharks that spend most of their time near the bottom looking for food. Despite their sluggish appearance, tiger sharks are one of the strongest swimmers of all the Carcharhinid sharks. Once the shark has come close to its prey, a speed burst allows it to reach the intended prey before it can escape (National Geographic).
Range Great white sharks live anywhere where water temperatures are between 54 degrees fahrenheit and 75 degrees fahrenheit. One of the densest populations is found in Dyer Island, South Africa. Great white sharks tend to be found in the presence of thick blubbery marine mammals such as seals and sea lions. Great white sharks are not just a coastal species. They have been found in the open ocean at depths down to 3,900 feet.
There are on average only sixty five shark attacks a year. A person is thirty times for likely to be struck by lightening. Sharks injure about thirteen people a year, but about two hundred thousand were hurt in accidents involving ladders, toilets, and chainsaws. The odds of getting attacked by a shark are very low compared to all of the other dangers in the world. Researchers are trying to explain to people through this theory that sharks don`t intentionally attack humans, they are merely just mistaking humans for their normal prey.
There are 70 species in this order, which includes the spied sharks, spiny dogfish, Sleeper sharks and lantern fish (I 50). Greenland Shark Classification: Kingdom: Anamalia Phylum: Cordates (possessing a notochord) Sub Phylum: Vertebrates (possessing a back bone) Super Class: Gnathostomata (jawed vertebrates) Class: Chondrichthyes (cartilaginous skeleton) Subclass: Elasmobranchas (ribbon like gills) Super Order: Selachii or Selachimopha (shark shaped) Order: Sqauliforms Family: Sqaulidea Species: somniousus Microcephalus (I 185) The shark’s habitat largely depends on the water temperature this allows its habitat that ranges from the Polar latitudes to the North Sea in the east and the St. Lawrence River in the West. The Greenland shark has also wonders south as far as the waters off Cape Hatteras and has also been found in the Gulf of Maine. The shark usually lives in cool water ranging from 2-7deg Celsius (II 63). However the sharks has also been found in the waters in the Artic Circle.
Our fears—and appetites—fuel an industry that hunts more than 100 million sharks each year and threatens to purge these vital predators from the oceans. The shark is an enchanting creature, over 400 different swim in the ocean today. Too many, sharks symbolize the terrible essence of ruthlessness, representing the ultimate savages of the seas. Although many folks would rather not deliberately socialize with these fearsome predators of the depths, I appreciate swimming among sharks. Sharks in addition to their direct predecessors are swimming within the world's oceans for well over three hundred million years, and were going about their business long before dinosaurs walked the world.
Great White Sharks are greatly misinterpreted as vicious man-eaters because of the media, movies, and people’s imaginations, but they are actually large fish who mistake people for seals and other marine life. What is a great white shark? The great white, among the least understood of Earth’s creatures, is an apex predator, meaning that it is at the top of the food chain with no natural predators. This means great whites have their pick of food when it comes to selecting their prey (Klimley 15). Carcharodon carcharias, better know as the great white shark, have existed as a group for over 350 million years (Long).
They have to move their whole body to swim rather that tail. Whale sharks grow up to 9 – 12 meters, when they are adults. The skin of the whale shark is yellow or white blotches. They weigh up to 12,500 kg. The heaviest whale shark was known to weigh 34,000 kg.
Perhaps that’s what is keeping vacationers from grabbing their trousers and snorkels. Over all, there have been 1026 attacks on humans by sharks in the last ten years. Only 294 of these attacks have been linked to Great White sharks. That’s roughly the number of people who drown each year in swimming accidents. Of these 294 attacks, less than eighteen percent were fatal.
