Biggest Shark Ever Found How Can You Tell If There's A Shark Nearby?

How can you tell if there's a shark nearby? - biggest shark ever found

I am terribly afraid of them, and I'm paranoid when I'm in the sea since I was a baby shark a few months in the shallow waters of the ocean, which means that the mother must have been found close. Anyway, check out my cousin a book that is the water clear and the waves are calm, but sometimes it is a great for him, that is, is a shark in the area. Please help?
