Sharks are big and strong fish. They are also dangerous for people. People who rest near the ocean and swim in it, must be always attentive because of these dangerous fish. Sometimes people want to catch any shark. But it should be done professionally. There is mind, that there is some quality in shark's body which can help in disease. That's why scientists are interested in sharks' anatomy very much.
But there are sharks which aren't dangerous for people. They live in the Black Sea. They are called Katran. But I think, in spite of this people should be attentive too.
As for me, sharks are great. They are beautiful and unusual creatures which have opportunity to live, as any other alive being.
