How are scientists certain that Megalodon is extinct when approximately 95% of the world’s oceans remain unexplored?

Would like to understand the scientific understanding that can be simply conveyed.

Thanks you.

Same reason they think Dinosaurs are extinct: Lack of evidence of life.

There’s be some sort of evidence if they were around. Dead creatures, poop, scavenging remains, etc. There’s **none** of that. Only fossils that are verifiably old as crap. True, they can’t be 100% certain, but to the best of our ability to reason, it’s reasonable to assume in cases like this.

The “95% of the oceans haven’t been explored” thing isn’t really true and really depends on the context. Do you mean the ocean floor? Then sure. But ships are criss-crossing the open ocean all the time, and a super large shark like Megalodon would need to be swimming around in open water near the coasts to find enough food. We’d see it. Additionally, we’d find a lot of newer teeth washing up on shore. All the teeth we find from Megalodon are very old.

On top of what others have said, most of the unexplored ocean is deep cold ocean while megalodons likely lived in warmer shallower (relatively) areas. So they wouldn’t be living anyway in the areas we haven’t looked

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
