Did you know that about 80% of the shark species have never attacked
humans? Sharks are found in all the oceans of the world, but there
are only four species that are considered dangerous: the great white
shark (known to most of us courtesy of the movie "Jaws"),
tiger shark, bull shark and oceanic whitetip shark. Humans are not
the preferred food of sharks despite public hysteria and opinion
to the contrary. Research suggests it to be a case of mistaken identity.
