However this is one of a few scientific investigations as sharks keep so many other interesting features and extraordinary abilities that were not investigated by scientists but are discovered day by day.

To meet the shark or not to meet

If you are the diver, you risk meeting the shark at least once in your life. But if you are the professional diver, probably you want to meet the shark. The professional divers are not afraid of sharks and they even like to play with them and to feed them. Nevertheless if you are the beginner and you don't want to risk, then follow some rules.

And of course the first and the main rule don't dive in the places where sharks live. This will save you from them for sure. But remember always that you are in the environment of sharks that is why you are the guest of the shark. So your behaviour must be natural, you should breathe silently with no sharp sounds and actions.

Usually trainers recommend the beginners to read some information about sharks. Sometimes knowledge got from the special instructions on behaviour when you meet the shark may be really useful. And if you have the instructor, operator or the expert in sharks, follow their instructions.

There are no dangerous sharks-killers. There are dangerous situations that may provoke the shark to show aggressiveness. And these situations are usually provoked by people when they start to swim away from the shark, start to fight with it, etc.

But if you met the shark, don't watch them, worry them and don't touch them. Remember that sharks are predators. That is why they are worth respect.
