According to archaeologists and scientists, we have only explored less than 5% of underwater worlds. This means there are sunken treasures, capsized boats, whole cities from centuries ago and, above all, creatures we never knew existed, lying at the bottom of our seas. So the seas around the world are still full of mysteries, just as in space, where alien life forms might be lurking in areas we haven’t explored. We have compiled some of the strangest and most incredible things recovered from the bottom of the sea and, yes, this list includes UFOs.
10 The First Computer Ever, from Greece: The Antikythera Mechanism
What is called the Antikythera Mechanism was discovered by sponge divers in 1900, from a shipwreck in Greece. It’s one of the strangest—and most amazing—things ever recovered from the bottom of the sea, because it is purported to have been built in 2nd-century BC. Another reason is because it has been touted as the world’s oldest computer, due to the fact that the device is supposed to chart the movements of planets and the passing of years.
Still, the use or actual function of the device remains unclear. It has only been pegged as the first computer because of its complexity in design.
9 Apollo 11 Engines Recovered By Amazon's Jeff Bezos
Last year, Amazon founder, Jeff Bezos uncovered components of two F-1 rocket engines from Apollo 11. They had been lying deep in the Atlantic Ocean, since 1969. And they are part of the craft that allowed astronauts to be sent to the moon for the very first time.
The engines are one of the strangest things ever recovered, not because it’s such a feat to have been found, but because Bezos’ efforts seem to have no underlying reason, as if one day he woke up and decided out of the blue, to recover the engines simply because it ‘s something he could do. Which is why Bezos funded the whole project and also why the press has called him "insane."
8 The Baltic Sea: Mysterious Circle-Shaped Object (Alien Aircraft?)
In 2012, Ocean X Team, the Swedish-based diving group, discovered a cylinder-shaped object while exploring the Baltic Sea. There’s much mystery surrounding the object, as its origins and functions are unknown. Some have claimed it to be an ordinary rock formation, while others have called it a “new Stonehenge.” Then there are the ideas that the object is a small underground volcano or a glacial deposit. It’s on our list because it’s been conjectured to be a UFO or a crashed extraterrestrial spacecraft.
This belief makes sense to some, simply because the object resembles the Millennium Falcon from Star Wars. Because of that resemblance, it must be something that tumbled from space. Somebody’s clearly been watching too much television. Still, we’d love for the object to be deemed as something alien. It tickles our imagination that other forms of life are out there. But the fact that it has been touted as just a plain object found at the bottom of the sea, quells the fun.
7 Cleopatra's Alexandria, Egypt and Their Underwater World
The existence of the Alexandria of ancient Egyptian ruler, Cleopatra has eluded many. Lost for 1,600 years, archaeologists finally unearthed parts of that world in 1998. It’s on our list as the strangest because, in an attempt to make it public and to be seen by the public, a proposed museum of Cleopatra’s city is in the works, making it the world’s first under-water museum.
From sphinxes to temples, and from statues to parts of a palace that have been conjectured to have belonged to Cleopatra herself, much of the city has been surprisingly preserved in almost perfect condition.
The United Nations insists that the underwater city remain in place to preserve its spot in history. This is why the plan of a special museum below the Bay of Alexandria's surface has been in the works. It will include the construction of tunnels within the museum for tourists to view the city and its remains.
6 Sea of Galilee: Mysterious Circular Stone Structure
In 2003, scientists discovered a very large circular stone structure in the Sea of Galilee in Israel. It’s one of the strangest things uncovered from the bottom of the sea because its function remains a mystery to this day.
The structure is made up of basalt rocks, and is twice the size of Stonehenge, weighing nearly 60,000 tons. The rocks form the shape of a cone. Archaeologists have postulated that the formation resembles a massive Bronze statue, or an ancient communal burial site. But the rocks remain a head scratcher, not only because its use and its date formed are unknown, but also because there have never been any findings similar in structure and in size found underwater. What we have is only speculation, and that's all we might ever have, as archaeologists find the rock formation hard to excavate because of its sheer size and because it’s a very costly endeavor. Who knows, maybe this is yet another discovery made by aliens bent on confusing us.
5 Lost Ancient Egyptian City of Heracleion
Heracleion, also known as the city of Thonis, vanished beneath the Mediterranean, around 1,200 years ago. The surprising thing is that it was discovered almost in its entirety during the last decade, submerged under 150 feet of water.
Archaeologists have discovered gold coins, 16 foot statues, as well as the remains of more than 64 ships. What is of interest is that the city, protected by sand at the bottom of the sea for centuries, has remained intact and preserved. What makes the city strange for something found at the bottom of the sea is that, to this day, and after so much research, speculation and above all, excavation, scientists and archaeologists still do not know what caused the city to fall into the water. And not only that, it has remained mythical, thought of as not existing, until only recently.
4 Doomed: More Than 10,000 Emeralds In 70 Feet Of Water
Amateur diver and treasure seeker, Jay Miscovich finally found his booty deep in the Gulf off Florida, in 2010. And what a booty it was. He discovered emeralds worth millions. This will go down as one of the strangest things uncovered in the sea because of the controversy surrounding the findings.
You’d think Miscovich’s emeralds would've made him wealthy. Instead, it just got him tied up in court after news broke and the feds entered the scene. A court order granted him only temporary custody of the emeralds, and because of that, Miscovich couldn't sell even a single carat. And then, there’s the mystery surrounding the emeralds—no one’s really sure where they came from. The story gets weirder—or creepier—because Miscovich killed himself, leaving many questions unanswered. Some said he could no longer wait to gain back what he found because he was deep in debt. Others claim he found being mired in a federal investigation to be his tipping point. The only thing we know for sure is that we’ll never be sure of what we know. Got that?
3 Bay Of Cambay, India - Sunken City
In 2002, archaeological remains of a lost city were found 120 feet under water in the Gulf of Cambay, off the coast of India. Said to be a chart-topping 9,500 years old, the city reveals that life might be more ancient than what Western historians and archaeologists have claimed.
The sunken city is one of the strangest things recovered because the architectural and human remains that were found, are still intact. Stranger still is that the lost city was submerged when the ice caps melted in the last Ice Age.
2 Life Persists Where It Would Seem Physically Impossible (Alien Existence?)
In 2012, microbes were discovered at the bottom of the ocean. They dated back to the Jurassic era when dinosaurs were alive. What makes this the strangest thing ever recovered is that the microbes were alive, and not only that, they have been alive for 86 million years. So much has fallen deep in the seas—whole cities from centuries ago, for example—that it makes it possible to believe that other lives, foreign lives, exist.
With barely enough oxygen, and with no fresh food supply during those 86 million years, the microbes are hanging on to their lives. It’s their very slow metabolism that has allowed them to survive. What’s amazing is that the microbes have been declared as the oldest living organisms in the world.
1 Spiders: They Creep You Out At Home And In The Water
Spiders are creepy. We know that. But did you know that spiders can live under water, making them the strangest thing found there?
These aren't weird fish creatures. These are actual spiders that breathe air but make their home under the waves, across Europe and northern Asia. They’re called Diving Bell spiders, so named for their sub-aqua webs that they fill with air in order to exist underwater. They only need to come up for air after many hours, although some scientists believe it’s once a day. Let’s hope the next time you’re swimming or diving, you won’t be pricked by these creatures.
