The largest shark that ever lived, the Megalodon terrorized the oceans for 20 million years with jaws wide enough to swallow a great white whole. At 60 feet long and 50 tons, its bite force exceeded 40,000 pounds—the strongest of any creature to ever exist on this planet. It went extinct three million years ago, and every ocean swimmer silently thanks evolution for that every single day.

The 40-foot, 9-ton apex predator that ruled the Cretaceous period with the strongest bite force ever measured in a terrestrial animal—12,800 pounds of bone-crushing fury. Its banana-sized teeth could pulverize anything that walked, ran, or made the fatal mistake of existing nearby. Sixty-six million years of extinction haven't diminished its reputation one bit.
