Despite their reputation as fierce predators, less than a dozen of the more than 350 known species of shark are any threat to humans.
In fact, the two largest species of shark (the whale shark, which grows to more than 40 feet in length, and the basking shark, which grows up to 32 feet), as well as the aptly named megamouth shark, feed predominantly on plankton they filter from the water they swim through.
