Here are the number 5 and number 4 mysteries shown in the video:

5) The USS Stein Monster

It was 1976 and the USS Stein headed into port after it’s SONAR system had experienced failure. Upon closer inspection at the port, the special rubber protective coating of the ship’s SONAR dome had cuts as long as 4 feet across. Within many of those cuts, the remains of sharp, curved claws were found – the type of claws associated with giant squid attacks.

However, these claw marks, measuring at around 4 feet across were much, much larger than any known squid previously discovered. Due to the size of these marks, it was speculated that whatever had done this damage could measure up to 150ft in length.

4) The Bloop

In 1997, multiple underwater microphones known as hydrophones picked up an extremely loud sound across a range of over 3000 miles. The sound was given the name “The Bloop.” The audio profile of the sound does resemble that of a living creature, except for the fact that it was many times louder than that of the loudest known creature, the blue whale….leaving the possibility open that a creature could exist much larger or at the very least louder than the blue whale. Others hypothesize that the sound was actually caused by a large icequake in Antartica…but the true source remains unknown.

We hope you enjoy the video.  Do you think any or all of these have some merit?
