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.

Hey, shark! Let's swim together

When people dive in certain place they may meet sharks that are rather peaceful and don't show aggression. For example, in the places of their living the part of the sharks' run will certainly get to the surface of water to the divers or people in the boat and will accompany divers during the submersion swimming round them.

The actions of sharks at the bottom of the sea are predictable. Sharks make the contact with people with pleasure showing their curiosity. Sometimes they provoke peoples' communication but not more. And among the lovers of diving, such sharks are usually referred to the Caribbean hound sharks, because this is the shark that is not harmful to people at all.

Sometimes the sharks' feeding is proposed as the additional entertainment to tourists. They may feed sharks both under the water and over the water. Those who are against such entertainment and those who don't mind have strictly different opinion on this point. After all the feeding takes place near the highly-populated places and such industry may influence the statistics of peoples' deaths from the sharks' attacks.

And this shark is considered to be the most dangerous being near the surface of the water that is why people use the methods of fast submersion and don't gather in the surface of water but at once under the water.
