When will sharks attack a human being?

Some sharks may attack human beings if attracted by underwater noises, erratic swimming, the presence of a large number of bathers, or the glint of jewellery or some other article. But probably the greatest provocation to a shark is the presence of blood, for instance from a speared fish or live bait. Sharks are most likely to attack during the daytime, the areas of the greatest danger being those where the sea temperature is between 16 and 21 degrees Centigrade. Most attacks seem to occur about 200-300 feet from the shore where the water is shallow-or no more than two or three feet in depth.
