Sharks have been depicted as man-eaters and killers for centuries. The reality is, however, that of the more than 350 species, only a handful — including the great white, tiger, bull and great hammerhead sharks — pose any threat to humans.
In actuality, through habitat destruction and overfishing, we've become more dangerous to sharks than they are to us. And if they were to disappear, all ocean life would suffer.
While we know this is true, admit it: the fun of Shark Week is watching those Great Whites chomp at the cages. But the Discovery Channel throws in lots of shark news and conservation info to keep things on the up and up. If your cooling off M.O. involves time in front of the tube, at least you'll walk away with some Cliff Clavin chum - er - trivia of your own to throw around. Tune in Sunday, July 30, at 9 p.m. ET/PT. :: Discovery Channel Shark Week
