Answer 1

The megalodon was a coastal creature not living in the depths of the oceans which is where that percentage comes from, humans have been on the surface of every available piece of water but safe exploration of the depths is what we are lacking. The megalodon we know of from teeth is not a creature that could survive in the depths of the ocean. Along with the significant drop In coastal water temperatures from 28 million years ago to when they went extinct 3 million years ago probably caused a significant loss of habits almost solidifying twits extinction
