Well megaladon is a giant SHARK and a blue whale is a giant WHALE
i think we have our answer
Megalodon wins easily because its species were fearsome predators while blue whales are mild, peaceful & gentle & they feed mainly on krill & blue whales live without attacking violently.
Megaladon wins easily. They were ferocious predators. Blue whales are passive creatures with no teeth and feed by living off of krill. This is a mismatch
Blue vs the biggest shark to ver live reaching 60 to 70 feet and weighing to 100 tons
