  2. How do we know some of these creatures were as aggressive as they claim? The Alligator Gar is quite menacing looking yet is one of the least aggressive fish, same thing with the sturgon. We've never able to observe these animals behaiviors so how can science make such bold claims about animals that have been extinct millions of years. We barely know anything about the behaviors of the creatures that currently exist in the open ocean, yet despite such factual inefficiencies science has no problem making these crazy assumptions about creatures they never observed. Like the super long neck one that had 7 ft long flippers. Just because he had 7 foot long flippers doesn't mean he goes to the bottom of the ocean. Perhaps he used those flippers to help swim up stream of a giant prehistoric river where they would breed and needed the powerful flippers to get up stream a river moving fast like the Congo river but 1 mile wide? We don't know if those long neck long flippers animals intruded into fresh like many animals do in the modern age, but it is stated with such certainty their purpose was for diving miles down into the deep. The statement doesn't even stand up to basic laws of physics because how would a creature with such a long skinny neck survive that pressure? The neck would be crushed paper thin. They make all these statements that cannot be backed up or substantiated.

  3. “…known to kill even the most well armored enemies…” I’m not completely doubting but how would it be “Known” for something. It would be nice to make it clear that this is speculation. Correct me if I’m wrong

  4. Megalodon still exists he was caught in 2016 to Scott 2017 and 2018 he's still alive he's lurking in the Mariana Trench never go down there he was caught in 1986 when a few people went down there with 20 ft camera powerlime then after a little bit something started pulling on it and then 6ft of the camera power line was bite off

  5. I think these creatures are alive somewhere. After all, the ocean is unexplored. I think they are just hiding or probably asleep. Some of you maybe asking how can something live for so long without eating? Well, maybe they have a special body structure that allows them to survive without eating for so long. It could also mean that they may be eating other creatures living down there that are also not discovered. But like I said, this is what I THINK, and these are just my random thoughts

  6. I remember something someone in my family went swimming and a bloop from 1987 swollowed them whole THEY DON’T EVEN HAVE TEETH WHY DID HE DIE well…my family is gigantic so it’s I guess 👌

  7. @Facts Verse please do top 10 biggest and terrifying flying creatures ever lived. Would be nice to hear about Quetzalcoatlus.


  8. Thumbnail is basically like:
    You see that giant Cthulhu in the background that is obviously a giant compared to a SEA SHIP? Yeah forget that, the real terrifying monster is the ship.
