Are sharks deadly

YES some are but not all sharks are the only sharks i heard that are super deadly are the Zanbezi shark great white shark the Meglodon shark the bull shark the lemon shark and the mako shark so all you have to do to not be shark chow is don't swim at night don't get in the water if your bleeding or have any open soars or cuts don't wear jewerly or anything shiny because a shark will think it is the scales of a fish and if you are in the water where you know there are sharks don't make huge splashes that also attracs sharks because they think a fish jumped out of the water and the splash would be the fish hitting the waters surface and to a shark there is nothing better then an afternoon snake.
