Of course we have no way of knowing if they are actually extinct or not. Now before you pass me off as crazy hear me out. 1: we know next to nothing about the deep oceans. 2: Megalodon is an apex predator.Combine that with its huge size and it is logical to believe that there would be very few of them with each one needing large swaths of territory. 3: Just recently several species of prehistoric fish thought to be extinct have been rediscovered so there is some precedent.
I agree. I also wonder sometimes what if Earth was as big as Jupiter. What kinds of crazy things would be able live there. Seeing as 7 billion people would be small ant farm in a giant field comparison wise. O_o
Whales survive on krill. Granted this is a more violent predator traditionally thriving on larger prey, but who says it didn't adapt to eating smaller prey? Plus, there are likely to be gargantuan life forms undersea. Who knows?
the one in battlefield 4 was actually too big for scale, but not much. the megalodon could still jump out of the water and take out multiple helicopters and not feel a thing, but the place it jumps out of is probably too shallow too. so yea. its pretty fuckin big.
How unlikely, though? A scientific example of a prehistoric fish being found after having previously thought to be extinct is the celeocanth (I may be spelling this wrong), and there is the occurrence of the "bloops" that have yet to be explained, happening around the depths that these things and larger are believed to exist in. Unlikely, maybe, but very far from impossible.
