As far as the question of these creatures being dangerous for human life is concerned, let me tell you that there are around 375 species of sharks available in all the oceans. Out of these, only about 30 species are responsible for the human attacks which are very dangerous for human kind.
Generally there are three classes of dangerous sharks
- Great White Shark (Carcharodon carcharias)
- Tiger Shark (Galeocerdo Cuvier)
- Bull Shark (Carcharhinus leucas)
All these sharks are to be treated with respect when it comes across to us. The reason behind is very common like any animal who will be threatened if someone comes near to it , so in order to protect themselves these sharks is prefer to attack .However when these sharks are starving they will surely eat whoever comes near to them. The chances of attacks on human beings are less than those who drowned in the oceans. It is believed that sharks won’t feed for human beings and it happens only if there is any mistaken identity.
There is an average 40-50 attack of sharks on human beings all over the world. However these numbers of attacks are increasing as the population is growing rapidly along with increase of usage of oceans for recreational purpose. These attacks will continue as long as the human beings will involve themselves going in the shark’s environment. Any shark which is more than 6 feet is always a threat to human being as they are big developed jaws and teeth.
There are two types of attacks on human beings Provoked and unprovoked attacks ,
Provoked attacks are generally happen because of human touching in which various divers are attacked after grabbing or feeding in under water.
Unprovoked attacks are occur when the shark make the first touch and these can be divided further into three types.
- Hit and Run attacks where normal injuries happen and deaths are rarely occur.
- Sneak attacks will takes place in deeper water in which severe injuries and deaths can occur if sharks will attack continuously.
- Bump and Bite attacks are the third type of unprovoked attacks, in which shark will bumps the person’s head and body which is quite severe and can occur death.
