Top 10 Deep Sea Mysteries That Still Remain Unsolved

“The ocean is 95% unexplored, unknown, unseen by human eyes.” 

Those large, beautiful bodies of water are home to an infinite number of strange creatures, and bewildering phenomena. The average ocean depth is 14,000 feet deep, which leaves a lot of room for the mysterious, the mythical and everything in between. Till now, there are a lot of deep sea mysteries can not be sovlved or explained by scientists.

1 Gulf of Mexico Shipwreck

Researchers testing equipment in the Gulf of Mexico inadvertently discovered the 200-year-old wreckage of a ship earlier in May, 2019. The long-lost vessel lies about 1,460 feet below the surface of the water, along a long, underwater cliff known as the Florida Escarpment.  Researchers haven’t been able to confirm details about the boat’s nationality, crew, rig or trade, the NOAA reported. However, the numbers “2109” were nailed to the edge of the ship’s rudder, and some iron and copper artifacts were spotted near the vessel.

2 Colossal Squid

Colossal squid, aka Antarctic cranch squid, are one of the largest, most elusive, and mysterious of the cephalopods. These massive squid are reported to measure up to 14 metres in total length with mantle lengths of about 2-4 metres (which would make adult colossal squid quite a bit larger than giant squid, Architeuthis dux) and they can weigh an estimated 150 kg.

These amazing creatures were first identified in 1925 when 2 colossal squid arms were recovered from a sperm whale’s stomach. Since then, few specimens have been recovered and there is still very little known about this species. Colossal squids have eyes that measure about 25 cm in diameter which are thought to be the largest eyes in the entire animal kingdom. They also have the largest beaks of any squid, which makes them a fearsome predator along with the 25 rotating hooks found in two rows on the ends of their tentacles.

3 Leptocephalus Giganteus

Leptocephalus giganteus is a species of ray-finned fishes with 0 observations, it has spurred debate over deep-ocean “mystery species” for decades, and more recently, have even become part of an unusual online hoax.

4 Aegean Sea Ruins

Am international team of archaeologists and geophysicists believe they have discovered a lost island in the eastern Aegean that was once home to the ancient city of Kane.

The island, is famous for its proximity to the 406 B.C. sea battle of Arginusae, at which the Athenians defeated the Spartans near the end of the Peloponnesian war.

5 Cuban Underwater City

Cuban underwater city refers to a site thought by some to be a submerged granite structural complex off the coast of the Guanahacabibes Peninsula in the Pinar del Río Province of Cuba.

6 Baltic Sea Anomaly

Dubbed the Baltic Sea Anomaly, the object is a 70-metre long strangely-shaped feature that showed up on sonar laying 100 metres (300 feet) beneath the waves.

Theories as to what the Anomaly could be have ranged from the interesting to the outrageous, with some claiming it could be part of fleet of crashed UFOs on ocean floor.

Some conspiracy theorists even point out it bears a striking resemblance to the Star Wars Millennium Falcon with a steel grey appearance.

7 The Milky Seas Effect

Milky seas, also called mareel, is a luminous phenomenon in the ocean in which large areas of seawater (up to 6,000 sq mi or 16,000 km2) appear to glow brightly enough at night to be seen by satellites orbiting Earth.

The above picture shows the first photo of the famous Milky Seas Effect. It’s a luminescence that turns thousand-mile patches of ocean a glowing milky blue.

8 Surviving Megalodons

The megalodon shark is widely regarded as both the largest shark to have ever lived on Earth and one of the largest vertebrate predators in history. Megalodons roamed the seas from around 28 million years ago until ~1.6 million years ago, when they were wiped out during the Pleistocene extinction.

Megalodons were, as we know, freaking huge. Some of the teeth discovered from this whopping great predator have been over 17 centimeters (7 inches) in total height, but the majority are between 3 and 5 inches (still, massive). Reconstructions using jaws and other fossilized remains suggest that megalodons probably reached maximum lengths of up to 54 feet (16.5 meters), around 3 times larger than great whites (C. carcharias). They even make T-rex’s look like pansies in comparison.

9 The Bimini Road

The Bimini Road, sometimes called the Bimini Wall, is an underwater rock formation near North Bimini island in the Bahamas. The Road consists of a 0.8 km (0.50 mi)-long northeast-southwest linear feature composed of roughly rectangular to subrectangular limestone blocks. Various claims have been made for this feature being either a wall, road, pier, breakwater, or other man-made structure. However, credible evidence or arguments are lacking for such an origin.

10 The “Atlantis” of Japan

On the southern coast of Yonaguni, Japan, lie submerged ruins estimated to be around 10,000 years old. We don’t know who built it, or when; but there it is, plain as day, available for anyone to go down and inspect. Even now, the current washes past sharply squared stone blocks standing dark and forbidding, rising nearly high enough to break the surface. It is called the Yonaguni Monument.
