Megalodon VS Blue whale - who would win?

 Did you know that Blue Whale are capable of defeating the megalodon?

Even though the megalodon is the biggest and the strongest shark the biggest megalodon can only grow up to 58 feet (18 meters) (though some argue it was up to 82 feet [25 meters]). By contrast, the largest blue whales clock in at a little more than 100 feet (30 meters) long, and on average are between 75-90 feet (23-27 meters) in length so this is an advantage to the blue whale so if the blue whale and the megalodon fought the blue whale will win
