30 Deep Sea Discoveries That Left Us Scratching Our Heads

psquared - May 31, 2019



The great white shark is the biggest predator of the deep. But what eats the biggest predator? Scientists think the answer might lie in the sharks themselves… specifically, in their stomachs. An enormous female great white shark was tagged to enable tracking for an Australian documentary in 2003.

About 4 months later, the tag showed up on an Australian beach with no explanation, leading scientists admit the possibility that their 9-foot long shark was eaten by another cannibal shark.

Don't Judge A Fangtooth By Its Cover

Even the name “fangtooth” inspires some fear. But the poor fangtooth fish is pretty harmless in terms of deep down underwater predators. And even if it tried to attack you (were you able to survive in its habitat), it wouldn’t get very far. Fangtooth eyes are terrible — like, they need seriously thick glasses — so they have to physically bump into their prey in order to attempt a meal.

Almost makes you feel bad for the little guys.

Atlantis Contender Number 1


The Japanese seas hold many mysteries. Could the famed city of Atlantis be one of them? Divers in 1987 looking for hammerhead sharks in the Pacific Ocean found a massive monument thing at the bottom of the sea, partially submerged. Now known as the Yonaguni Monument, the structure is 450 feet by 130 feet and close to 90 feet high.

Haters say it’s all natural, but true believers say it’s at least 9,000 years old. Keep reading for even more terrifying things lurking in the sea.

The Name Says It All

The hatchetfish sounds terrifying, but it has really just been blessed with a thin, see-through body and a funny hatchet-looking thorax. They’re only a couple of inches long, but staring into their creepy little eyes will still make your life flash before your own.

Scary, sure, but likely to attack you? Not unless you’re hanging out in the deepest depths of the ocean.

Nessie's Russian Cousin


Everyone’s heard of the resident monster of Loch Ness. But what about the Water Dragon Master of northern Siberia? In Lake Bital, the world’s deepest lake, mysteries and legends abound about this massive monster. Not only do modern fishermen tell stories of Water Dragon Master sightings, but there are also stone carvings from the 3rd century BCE depicting the same exact thing.

Siberia might hold a family of ocean monsters, but read on: not all sea monsters are massive.

Not all crazy stuff in the ocean is enormous. Groups of luminous bacteria sometimes fill the sea and create visions even more terrifying than a shark’s fin or a group of approaching jellyfish. Once known as the Milky Sea Phenomenon, this sighting isn’t new, but samples taken of Arabian Sea water in 1985 led researchers to discover the tiny life forms behind the spooky water color.

Massive groupings of these little bacteria make the water look milky white and glow-y, a definitely creepy sight when you’re out in the middle of nowhere bobbing around in the dark.

Proof Of Life


A giant rock sitting in the bottom of the Baltic Sea wouldn’t be that big of a deal. But a giant metal Millenium Falcon? That’s a possible extraterrestrial crash site. This 200-foot wide object at the bottom of the Baltic has been prompting questions ever since it was discovered in 2012.

True believers think that this thing is over 140,000 years old, total proof positive of life beyond our universe.

Atlantis Contender Number 2


Egypt is home to ancient relics, stone statues, and some of the greatest mysteries of the world. But could it also be home to the mythical Atlantis? Off the coast of Alexandria, Egypt lies an underwater city full of gold coins and statues and temples, but no explanations as to how it got there. Researchers think the city was functioning nearly 2,300 years ago, but that’s all the French archeology discovery team knows for sure.

But it’s probably aliens, right? If you don’t believe now, keep reading for more evidence.

When Was Ice Cream Invented?


The picture of an ice cream cone is pretty iconic. But why would ancient peoples carve a giant ice cream cone out of stone and then throw it in the water? We may never know, but in 2003, researchers using sonar imaging found what seems to be just that at the bottom of the Sea of Galilee.

This big ol’ cone (it’s over 30 feet long) is just lying in the water now, waiting for the perfect scoop.

Freaky Fishies


There is a lake that has never been touched or even seen by humans. Satellite imaging discovered this lake under the Antartic ice in 1993. Suspicions about what this lake may hold are as vast and wide as the Antartic itself: fossils? Live fish? Nothing but frozen water flowers?

We may not know what lives in this lake, but the keep reading to learn about some weird known lake inhabitants.
