A body of water that 39 percent of the American population lives near about a mile of the scariest thing. For starters, we have barely explored any of that. And the parts we have actually explored are full of murderous monsters, diabolical natural forces, and black holes that look like another world. Yes, black holes are not relegated only to space.

However, this is not all; In fact, this scary trivia treasure barely scratches the surface of why the ocean is the oldest horror show in the world. So, if you want your knuckles to turn as white as the crest of a tsunami wave, read on. Just don’t say we didn’t warn you. And for cheaper emotions, check out the scariest facts about the ocean that will blow your mind.

Hurricanes can cause the greatest devastation when they land, their base of operations is in the ocean.

And when these ocean-based storms land, they land hard; In 2017 alone, 103 Americans died as a result of the injuries suffered in hurricanes Harvey, Irma, José, and María. Solar eruptions — storms from space — bounce harmlessly into our ozone layer.

The black hole in the ocean

Do you think space is home to all our black holes? Think again In scariest facts, the ocean is full of swirls similar to black holes in space, which means that nothing in your path can escape. Even more frightening, black holes in the ocean are massive, often measuring up to 93 miles in diameter. For the context, that is bigger than the whole of the great Los Angeles.

New creatures

If you think jungle beasts are horrible, you still haven’t seen anything. Creatures like the fangtooth (!), the goblin shark, and the flying shark are much scarier than anything you discover on land.

Even more frightening, we always find new monsters in the ocean: in fact, the largest colossal squid ever discovered was found only 11 years ago. Imagine what we will discover in the next 11 years.


While it is nice to imagine that there is nothing but placid water beneath us when we take a dip in the ocean, the reality is much scarier. In fact, the Intergovernmental Oceanographic Commission estimates that the ocean floor is home to the staggering 3 million shipwrecks. Space designated as any elevation above the Karman line has claimed a relatively small number of four ships.


It is understandable that you do not want to meet a shark while swimming, but the annoying jellyfish, of which there are millions in the ocean, can be a great threat to your life.

Thanks to their venom and the relative lack of detectability underwater, jellyfish have a body count five times greater than that of sharks. Again, we have never encountered a single creature so terrifying in the cosmos.

Filled with garbage

The ocean can look beautiful from that pristine stretch of the beach where your margarita is drinking, but make no mistake: it is a huge trash can. In fact, the Great Pacific Garbage Patch, which lives between California and Hawaii, has grown to 600,000 square miles, more than double the size of Texas.

Terrifying Predators

But, as you know, sharks are not the only danger that swims just below the surface. The National Ocean Service reports that the Australian box jellyfish is the most poisonous marine animal in the ocean.

These potential threats, along with the Pufferfish, which contains enough toxins to kill 30 adult humans, for which an antidote is not known, and the Barracuda, which can reach speeds of up to 25 miles per hour during the attack.


In total, these natural disasters at sea have killed about 175,000 people and can be caused by earthquakes, volcanic eruptions, landslides, or, basically, any large-scale disturbance at sea, according to the National Ocean Service.

While there are some ways to protect against these disasters, it is almost impossible to take into account the walls of water several feet high. In addition, the most devastating thing that hits our planet from outer space, an asteroid, causes most of the damage through the resulting tsunami.

Lighting magnet

While lightning may not hit the ocean as often as the earth does, when it does, the results can be disastrous. Because water is a conductive substance, lightning spreads rapidly and can electrocute any person, animal, or ship that is in it.
