Great White Shark
The great white shark is the largest sea predator, growing up to 21 feet and weighing 5,000 pounds. It doesn't have feeling in anything but its mouth, so the great white bites before it eats to see what an object is. Great white sharks have been caught biting buoys, piers, surfboards and yes, humans. It's more likely to bite, though, not kill, even though many people believe otherwise.
