You can find out more about the great white shark from books, but until these are delivered, you should entertain yourself with the information offered in this video.
And if you are so interested on the topic that you want to see the movie made by Spielberg, too, prepare for it by watching the following trailer.
You will be impressed by the great white sharks and you will learn a lot of new things about them.
It is true that these sharks have killed humans. However, they do not typically target them. For instance, 31 confirmed attacks against humans have been confirmed in the Mediterranean Sea in the last 2 centuries. Most of these attacks were not fatal and seemed to have been “test bites”. This is because every great white shark is a test biter, grabbing buoys, flotsam, surfboards and other unfamiliar objects in order to identify them. Humans make no exception. Other attacks have been caused by the sharks believing that a bather’s or surfer’s silhouette is from a seal. Moreover, some scientists have even reached the conclusion that these sharks do not like the taste of human flesh. Not only do sharks attack people, but also boats. These attacks are infrequent, but can still lead to the boats sinking. In captivity, white sharks do not live long. While they can have a life span of over 30 years in their natural habitat, they barely live 16 days in captivity.
Even though great white sharks have an infamous reputation, people seem to be attracted by them. Tourists are very appealed by these predators and are often unaware of the danger they pose. Diving neat sharks of most species is safe, but diving with these great whites requires great care. People who want to see these sharks up close should not do it without being “locked” within a steel cage. This is why cage diving has become very popular, especially in the waters of South Africa, South Australia, and Guadalupe Island. In relation to people, great white sharks are not to be messed with. While some people claim that shark attacks on humans are not common, these predators can still grab humans in an instance and play with them as if they were toys.]]>
The only sea creature that could possibly match of the great white shark is the orca, which is another name for the killer whale. The interesting aspect is that orcas are not even whales, they are actually dolphins, but they kill whales and great whites. The great white plays an important role in keeping the ocean clean. You might consider the great white as the doctor of the ocean. They not only eat, or at least take a bite out of, anything that is in the ocean, they eat weakened, sick or injured sea creatures. Surely, you have heard of the expression survival of the fittest. In the seas and oceans of Planet Earth, this is especially true. There are no undersea doctors and surgeons to patch up fish when they are sick or injured. This is where the great whites come in and clean things up.
Great white sharks, also known as white pointer sharks, or sometimes just white sharks, live in the coastal temperate regions of the world’s seas. They avoid warm waters. They best live in cold waters. Scientists tell us that the great whites prefer to live in cooler waters. The great whites live in the Pacific Ocean, along the eastern seaboard of both America, South America, Australia, New Zeeland, China and Japan, Indian Ocean off South Africa and the western coast of Australia, and in the Atlantic Ocean, off the eastern coast of both the USA and South America, North and South Africa, France, Portugal, and the Mediterranean Sea.
Another interesting aspect about the great white is that just like any other animals, it sleeps. While some rest on the ocean floor, others can rest one side of their brain at a time, allowing the other side to remain alert for predators.]]>
People were attacked and killed by the great white sharks. A few of them have lost an arm or a leg, their lives changing completely. The killers were the great white sharks, obviously. These creatures may attack by curiosity or even by fear as they are not used with people swimming in their territory. Other surf in those dangerous waters, although they know that these are the places where many great white sharks live. Nonetheless, they start to practice their favorite sport, but the adventure doesn’t always have a happy ending. People should be aware that their lives are in danger, so they should avoid swimming or surfing in the areas where a lot of great white sharks live.
We tend to think that this couldn’t happen to us, but the lives of many of us are completely ruined after we meet the great white sharks. There were cases when although people were very close to the great white sharks and very vulnerable, these creatures didn’t attack them. The same thing try to do the scientists. They want to prove that the great white sharks don’t attack as they are ferocious and aggressive killers, but because they are confused, curious or are afraid. Nevertheless, the films with great white sharks made people fear them even more and changing their opinion about these creatures is very difficult.]]>
Great white sharks try to avoid fighting for food. When there is only enough food for one, they have a tail-slapping contest. The sharks swim past each other, each slapping the surface of the water with their tails, and often directing the spray toward the other shark. The one of the two great white sharks who gets the meals is the shark that delivers the most tail slaps.
The great white sharks is actually not white. The colour of their bodies can range from dark blue, grey to brown or black. Their name comes from their universally white underbellies. The great white sharks rarely attack people, lest they should smell fear or blood. If you take a closer look at the snout of a great white shark, you will see that it is scratched and scarred. This is because of the fights they have with their prey. The great white shark eats so much that the food lasts for three months before needing one. Regarding the scratches on the snout, the great white sharks can also roll its eyeballs back, thus protecting the vital front part of the eye from being damaged. It is a known fact that most of the times, great white sharks fight with Orcas, better known as Killer whales. The Killer Whale is the only other predator that has been known to kill and eat the great white sharks.
The great white sharks are on the list of endangered species, since there are less than 10.000 sharks in the entire world. This is due to extensive poaching and the fact that great whit sharks breed late in life. They do not start breeding until they are at least twenty years old. Although they are dangerous predators, most of the people who have been attacked by the great white sharks, have survived. The shark realises it has made a mistake and does not finish off the prey.]]>
The great white sharks are the third largest fish predators in the world. They grow to an average of 15 feet in length. Though, there are some specimens that exceed 20 feet and weigh up to 5000 pounds. The bodies of the great white sharks have a greyish colour that blends in with the coastal sea floor. This helps them to camouflage when they are hunting for food. The bodies of the great white sharks have the shape of a torpedo, with sleek lines. The great white sharks take their name after the colour of their underbellies.
Another feature that makes the great white sharks such interesting animals is their capacity to rip off the meat. The mouth of the great white sharks has more than 300 triangular teeth arranged in several rows. Although the great white sharks don’t have keen sight, they have special organs that detect the electromagnetic fields generated by animals. Their method of attacking is catching the prey from underneath and not letting it go. The main prey the great white sharks feast on consist in sea lions, small whales and even sea turtles.
The great white sharks are found in cool, coastal waters all throughout the world. Scientist and marine biologists agree that their number decreases by the day, due to overfishing and accidental catching in fish nets. Moreover, the great white sharks are on the endangered species list, and if poaching and fishing will continue, soon enough the great white sharks will be in danger of extinction.]]>
There is a high debate right now concerning the great white sharks and their conservation status. The overfishing and poaching of the great white sharks has caused the decline of the shark population from the 1970s to the present. The great white sharks are now considered vulnerable. Fishermen target many great white sharks for their jaws, teeth and fins, and as a game fish in general. The great white sharks are however an object of commercial fishing, although their flesh is considered valuable. As of April 2007, the great white sharks have become fully protected within 370 kilometers of New Zealand and additionally from fishing by New Zealand flagged boats outside this range.
Still, the great white sharks represent a major source of tourism. Their infamous reputation enable tourists to dive near sharks, surrounded by a cage, to avoid any attacks. Cage diving is one of the most common tourist attractions on the coasts of Australia, South Africa and Guadalupe Islands. Cage diving and swimming with the sharks is a focus for the booming tourist industry due to its popularity. A common practice is to chum the water with pieces of fish to attract the great white sharks. These practices may make the great white sharks more accustomed to people in their environment and to associate human activity with food.]]>
Scientists tried to counteract this general belief about great white sharks by conceiving different experiments. These experiments involved humans that swim with great white sharks or even touch them. By doing so, they are trying to change the image about great white sharks, which are described as being very dangerous. There are theories saying they attack by fear, curiosity or when they take humans for their prey, so they are confused.
It is true that these creatures look very frightening due to their huge size, length and weight, but we still do not know very much about their lives. It is sure though they adapt very well and very fast to any habitat and are real survivors. Although they look so, great white sharks are still beings sensitive to pollution. Besides, they are also very hunted for soup and for manufacturing pills from their organs, so they are in danger. Without great white sharks, the natural balance would be completely turned upside down. So, these animals need protection even if we do not like them or perceive them as dangerous and horrible creatures. Too many animal species are extinct, but it is our responsibility to do something about it and stop endangering these beings.]]>
It is true that the great white sharks look terrifying and also like some monsters, but they are just animals that see humans as something unusual for their habitat. Sometimes, great white sharks can get scared and they overreact by attacking people. These animals exist for many years and they survived even when climate changes happened. They managed to adapt to all the new environments and they are still very strong animals. For the sake of our life, it is recommended to avoid the places where great white sharks live. Great white sharks image became negative after releasing films where great white sharks were presented as ferocious and very aggressive animals that were killing a lot of people. Since then, people had in mind those horrifying images with great white sharks killing people, but is not something that always happens.
Later, there were TV documentaries which presented scientists who dived into the waters where great white sharks lived and they were inoffensive. The scientists were very close to the great white sharks, they even touched them, but nothing bad happened. So, this subject is very controversial and the idea of great white sharks attacking and killing people is still debated. There are different opinions about this subject and the scientists still need to search more and to make other experiments, so we will have a better idea about sharks’ life. We judged these animals too soon, but it is time to think different.]]>
The major facts about great white sharks should also regard their life span. It is well known the fact that great white sharks live in average 25 years, while many individuals of these species can live more than 30 years. It has always been considered that great white sharks reach their maturity at 15 years of life. Other facts about great white sharks is that they are the most common attackers of humans. Because great white sharks can be found in most oceans, they are going to easily be able to enter into contact with humans. Most cases in which humans are attacked by sharks, involved great white sharks, as statistics show. Many great white sharks can be found in the Unites States, South Africa, but also the Mediterranean. Some of the most interesting facts about great white sharks is that their meat is not recommended for consumption for humans, as great white sharks are known to have a high mercury level in their body.
Despite their size and the fact that great white sharks are very strong, they do not necessary like to fight to obtain their food, so attacking humans will not be a purpose for them. Attacks occur when great white sharks mistake the person with their usual prey. This is actually the main reason why the victims of great white sharks are not necessary killed, but they are abandoned by the shark once it realizes that it was not the prey they looked for. Great white sharks do not finish the prey in such cases. Great white sharks have a huge liver and it is has been said that the liver of a great white shark actually is representing 24 percent of its weight. Although they are called great white sharks, these sharks are not necessarily all white, as they can be found in other colors, such as blue, gray, brown and even black. During their lifetime, great white sharks can change up to thousands of teeth.]]>
