We all know that the ocean is a deep, and sometimes, frightening place. Massive creatures with large threatening teeth are just one of the things that have been found in the depths of the ocean, but there are even more terrifying things out there to be discovered. If you’re already afraid of being in the ocean, then you should just stop reading right now because this list will surely give you nightmares.In 1987, an odd structure was found off the coast of Japan. The structure has parallel faces, holes, sharp edges, and a triangular shaped pool. For obvious reasons, it was nicknamed “Japan’s Atlantis” and has been the center of debate for over 20 years. Some people believe that the structure is an underground city hidden from the public eye, while others believe that it’s simply a unique rock formation.

The Ocean Exploration Trust was established in 2008 by Dr. Robert Ballard to engage in ocean exploration and education, and explore they did. In 2016, the organization discovered a strange purple blob off the coast of California. At first, they joked that it was a giant spider sack or an octopus, but still, they couldn’t figure out what it was. The identity of the Blobus purpilis is still unknown!

While Swedish explorer Peter Lindberg, Dennis Åsberg, and their crew were at the bottom of the Baltic Sea in 2011, they came across an unknown structure. As the divers got within 200 meters of the strange object, their electrical equipment malfunctioned. The crew noticed from sonar imaging that the anomaly had what appeared to be a perfectly round hole, a staircase, and square framing. As you can imagine, the photos had many people speculating that it was a UFO wreck. Professor Volker Brüchert of Stockholm University believes the structure was formed during the Ice Age after studying some of its rock samples. But Brüchert did add that the samples might be hiding something else beneath the surface, possibly something artificial. Unfortunately, news articles claimed that the structure was debunked, so Lindberg and his crew have been unable to get financing to return there to see if it’s artificial or natural.

In 1997, a very strong, ultra-low “bloop” was recorded by several stations, which happened to be thousands of miles away from one another. Scientists haven’t necessarily ruled out that the sound, which has never been heard again. The scientists can keep looking into that one, but we think it should be left alone.

Erosion is natural occurrence that happens everywhere in nature, even in the ocean. Twenty feet down into the ocean, off of the Bahamian shores, a long, abandoned road was discovered. Now, while finding a road under the water would be absolutely insane, geologists and archaeologists are in disagreement over whether it’s an actual road or just natural erosion.

As you should already know, most of the world has already been explored and mapped out. And while most places tend to be in the same place, some places mysteriously vanish. This is the case for the island of Bermeja, which was located in the Gulf of Mexico. Did you notice that we used the word “was?” Well, that’s because Bermeja can no longer be found! Mexican officials investigated the area, but they weren’t able to find anything. It’s believed by conspiracy theorists that the CIA had something to do with the island’s disappearance.

Antarctica is a vast uncharted land of ice, snow, and of course, penguins. Recently, a staircase-looking structure was discovered in Antartica through Google Earth. Most scientists believe that the structure is just an impact mark from a crater, but others, of course, believe that it could be UFOs or even an old Nazi base. All we know is that whoever would land on Antartica is out of their mind, obsessed with penguins or a glutton for icy-cold punishment.

For centuries, scientists, archaeologists, and unsuspecting travelers have stumbled across ancient ruins. In 2002, though, marine scientists discovered an archaeological structure from an Indian city that was approximately 9,000 years old! That makes it the oldest civilization ever discovered! But once again, people are skeptical about whether or not it’s real.

Humans have been recording the sounds of whales in the ocean for many years. While most of the whales have always sounded the same, there has been something going on with the mating calls of the Blue whales! Recently, marine biologists studying the whales have discovered that the Blue whales mating sound has become a much deeper frequency. Many scientists believe that the change in pitch is due to an increase in the competition for mates!

This incredibly large eye was discovered floating around in the ocean water near Fort Lauderdale, Florida. Scientists believe that the eye was from a rather large swordfish or a deep-sea squid, but it seems that some human interaction was involved since it was perfectly dissected from the unknown creature.

Strange sounds have been recorded coming from the Earth for as long as we can remember, but one sound, in particular, caught the attention of scientists. In 1991, scientists recorded a sound that they couldn’t identify. Since they first discovered the sound, it has been detected in several different areas of the Pacific Ocean. While they can’t be too sure, scientists believe that the sound is lava coming into contact with the ocean water. Let’s just hope that they’re right.

The mummified body of German sailor and explorer, Manfred Fritz Bajorat, was found in his yacht floating off the coast of the Philippines in 2016. Bajorat’s mummified body was found sitting at his desk, slumped over like he had dozed off. Bajorat had apparently gone missing in 2009, so it wasn’t a surprise to find his mummified corpse until they did the autopsy. According to the post-mortem examination, Manfred had only been dead seven days when his body was found, so how was he already mummified?

Great white sharks are one of the largest predators in the world, which makes this recent discovery extremely unsettling. Several years ago, the battered and bloody of a 9-foot-long great white washed up onto the shore. Scientists believe that something MUCH larger ate the shark. Some people suspect a massive great white cannibal of killing the shark!

Here we go with those strange sounds coming from the ocean again! In 1999, a recording was made that astounded scientists. The recording, which was 15 seconds long, was completely unrecognizable. At the time, they had no clue as to what could make the sound, but now, scientists believe it was the sound of an iceberg hitting the bottom of the ocean in shallow water.

Stories told by sailors about stumbling upon milky, florescent seas have been circulating around the world for centuries. While many sailors told tall-tales about mermaids and massive sea creatures, this story has a logical reason behind it. According to scientists, this glowing phenomenon is actually caused by bacteria that illuminates the water.
