Killer sharks 322 bite for recorded people turned out to be for defense purposes. The result revealed that this species, which is considered to be quite dangerous, bites people because they were afraid of people.
These malicious fame of sharks, which have been shown as a serial killer for decades, remain disproportionately compared to the attacks on people.
An average of 100 shark bite cases are recorded every year around the world. 10 percent of them are deadly.
Statistics that do not fit much about the script depicted in the legendary Jaws movie.
A study published by the group led by Eric E. Clua at the University of Science and Literature of Paris shows that this fame may be unfair.
In the analysis of the French Polynesia, what triggered shark bites was investigated.
The results showed that sharks sometimes bit themselves to defend themselves and that the injuries were superficial. In other words, some sharks observed in the research did not bite people because they were looking for food. The main motivation of these behaviors is the instincts protecting themselves. In addition, its bites are severe, but it is not usually not lethal.
If a shark is attacking to feed, the victim will seriously lose meat and die due to bleeding.
Clua, “whether it is deliberate or not in responsible for shark attacks. They have entered their environment,” he explains the situation.
Bears, such as camel birds, animals attacked people against people had previously observed. For the first time for sharks, such a conclusion was reached.
Experts compared 7 thousand bite recorded since 1963. In some of these attacks, it turned out that people were attacked while having activities such as fishing or entering the shark area.
In his articles published in the Conversation Science magazine, scientists who classify the bites as provocative and non -driven, found that a total of 322 bits that took place worldwide may be for self -defense and that there was a 3.2 percent mortality rate. Aggressive sharks were usually medium -sized. So it was shorter than 3 meters. Particular attention was the black -tipped shark and gray reef shark.
The shark bites have been recorded since 1940 in Polynesia archipelago consisting of 118 islands. However, the main reliable information is in the records since 2009. In these records, a total of 74 bite was documented, while 4 of them were for the purpose of defense.
