Carcharodon Megalodon (meaning giant tooth) was the largest and most powerful predatory fish that has ever lived. Megalodon also had the strongest bite force of any animal that has ever lived, at up to 18 tons. That bone crushing jaw strength allowed it to commonly hunt whales for its meals. Its teeth were similar in structure to today's Great White but significantly larger. Some Megalodon teeth have been measured over 7" in length. Compare that to the average 3" tooth size of a modern Great white and one can begin to imagine the size and power of Carcharodon Megalodon. The beast could grow to over 30 meters long.
