    The shark story was amazing.
    And then the following story shows Mrs. Thatcher! That was pretty cool.
    I think the Saratoga fell victim to the bubble phenomenon.

    I mean yeah, about 95% of the ocean floor is unexplored, but to say we know more about the "outer reaches of space" has got to be one of the most ignorant things I've heard on this channel....

  • Paranormal Activity and Mysterious Stories

    there's so much about the ocean that we don't know. i've been using google earth and discovered all kinds of high strangeness on the ocean floor. i also believe people at google maps are deliberately covering up know ancient settlements that were covered when the sea levels rose.

    Let's see, the Upsweep:
    sounds like a chorus of the damned
    likely originates from an area of volcanic activity
    is heard more in Spring and Fall, aka Easter time and Halloween time
    Now folks, I don't mean to make any wild assumptions, but it seems we've found the Gates to Hell

    I think the tracker on the Great White Shark probably somehow came off and fell to the ocean floor. Another fish mistook it for food and ate it. Then, the other fish passed or puked it up, or was attacked. The tracker was caught by the current and take to shore. It explains why it suddenly descent, the sudden temperature change and the ascent.

    There’s no such thing as an underwater waterfall it is in fact a trick of the eye, caused by the formation of sand and silt on the ocean floor.

    What is with the way these narrators pronounce things. On another video Tahoe was pronounced tay-ho.... 🤦🏻‍♀️🤦🏻‍♀️

    (at 1:30) Can anyone tell me exactly where "O-wah-who" is in the Pacific Ocean?? Can't seem to find it in the same position on MY world map as shown in this video. I sincerely hope the narrator isn't just attempting to pronounce "Oahu..." and the graphic of radiating concentric circles isn't as far off the mark as it seems...

    • HELLOkitty8O8
      HELLOkitty8O8 9 months ago

      Pat (Smithson) Peña Oahu is one island that makes up the Hawaiian islands that is the 50th state of the US and is situated in the Pacific Ocean. Narrator should’ve said off the coast of Hawaii not just Oahu. And that is not how it’s pronounced either. His way or your way.

    What I consider a giant squid is a Body the size of a submarine and tentacles hundreds of feet long. Not the one's that have been found. Those aren't giants. The same holds true with most everything else They call giants.

    I really like your stuff! But please don't stop in the middle of the videos to ask for people to subscribe, or click on the goddamn notification bell! That is seriously enough to make me want to say fuck this shit! And look elsewhere! You are aware that there are other similar RU-clip channels on here right!? Because maybe you could do some research on that topic and realize that you are not alone! And there are several to choose from! Just stop pausing the video and begging people to subscribe like an idiot! Just make a really good video with Theraflu thoroughly researched information and I can promise that the subs will happen!
    People will always follow and show support for the channels that seem to be honestly doing the work and at least trying to pay attention to what the commenters are saying! Other than the stupid shit like you need to get your nose done! Or you need to have bigger boobs!
    First of all, fuck those Sumbitch, little bastards don't matter! They're 13! Just do your research about the subject you're going to do the video on and continue just like you have been doing! I'm sorry I got in the way! I was only trying to mention that I really don't like anything about the way you stop the video to beg for the viewiers to please press the subscribe button and then and even after that, you ask them to please press the notification bell!

    If it is anything I learned from my time in the submarine force, fires are common. If they last longer than 2-6 minutes most if not all the oxygen would be used up by said fire.
