10. Megalodon
Can you imagine what a pair of 7.1 inches long teeth could do to a human.. or a ship? Well, Megalodon is a species of extinct shark that may have been the most powerful vertebrate predator on Earth. It was 59 feet long and, thankfully enough, it lived about 2.6 million years ago. Just to get a point, a Megalodon’s bite was 10 times stronger than that of the largest white shark today.
