Abstract
Sharks are marine predators, well known as bloodthirsty killers by humans owing to the incidence of shark attacks and subsequent human casualties. But for these 4 or 5 people killed in a year, almost 100 millions of sharks are killed each year. According to the association "Shark savers", 97 to 99% of regional populations of shark species are gone already, and within 5 to 10 years, there will be no more sharks in the water. The great white shark is now listed as "vulnerable" in the International Union for the Conservation of Nature (IUCN) Red list, because it is currently in a high risk of extinction. It is now more urgent to protect them because they have a very important role to play in the functioning of an ecosystem in the oceans, as keystone species. This aspect will be developed later in this report.
Indeed, multiple causes are involved and humans are, of course, responsible for this massacre. Many governments are now aware of the magnitude of this phenomenon, and steps have been taken, but the killing persists, and the white shark in all likelihood will become extinct. The great white shark is one of the most dangerous sharks in the world. Its name was given because of the white color on its abdominal area, despite the fact that its back is grey. Its Latin name 'Carcharodon caracias' means "shark with sharp teeth" in Greek. It deserves its name because its teeth cut like a razor blade, it allow the white shark to kill any prey. the teeth can renew itself in their entirety in just 8 days. The white shark can be found near the shore in cold water as in warm water.
