6 Deep Sea Creatures That Will Convince You Aliens Exist

6 Deep Sea Creatures That Will Convince You Aliens Exist

Statistically speaking, aliens probably exist, right? Like there are an estimated 10,000,000,000,000,000,000,000,000 planets floating around–and that’s completely ignoring the countless rogue planets that could also maybe harbor life. Which is… Unlikely. But even if less than 0.000000000000000001% of planets had life on them, you’d still be looking at more than 100,000 planets with life. But sure, life is fragile. So let’s look at some wildly extreme deep sea creatures that might convince you life is less fragile than we think.

But at the same time, stepping on a Lego brick will put us out of commission for an entire day.

As a preface, the deeper parts of the ocean can crush you with up to 9,000 pounds per square inch. Its temperature is right above or even at freezing for the water in your fridge (salt among other things makes ocean water freeze at temperatures below 0 degrees Celsius). There’s no sunlight, which means the prime source of energy in many ecosystems is gone, and our deep sea friends have to find an alternative.

The Giant Squid

Are we talking about Cthulhu, or are we talking about an actual giant sea monster that sometimes washes up on our shores. Some have been measured to go up to 59 feet in length and weigh up to a ton. That’s just the handful we’ve seen washing up on our shores. 

Given that we humans have probably known about giant squids for a good while, it’s no wonder the Kraken is a thing at all. 

Also, just remember that the giant squid lives in an almost zero light environment. Which means that you actually won’t be able to see this 60 foot monstrosity until it were to be right on top of you. Want proof? Here’s a video.

Nobody tell our readers about the even bigger colossal squid.


If you’ve ever wondered whether or not you could give yourself a monster jaw, well you’ve probably got some weird superpower fantasies. But there does exist a fish who has you covered. These long boys can crack their jaws open up to 90 degrees and eat stuff that’s up to and potentially over 60% their own size. 

That would be like you fitting an entire person and a half inside your belly at once. 

Unfortunately for the viperfish, this jaw blessing comes with a huge curse–which isn’t living in the ocean deep (though that’s kind of a curse in itself). Viperfish teeth can’t move like many other fish teeth (which apparently can kind of squish back down into their mouths). So to even fit anything into their maws they have to open their mouths that wide. Makes sense when you realize viperfish teeth are more about turning their mouths into cages than actually ripping stuff apart.

Also viperfish trivia, the bottom of their mouths is open for no reason other than “let’s open our massive mouth even wider.”


Known for their little head bulbs that light up, the anglerfish is probably one of the first things you think of when you think of the ocean deep. Like the viperfish, many of the over 200 species of anglerfish have really big teeth. So big their mouths don’t really close properly too.

But here’s something you probably didn’t know about the anglerfish that makes them nutty enough to make the list. That’s their extreme sexual dimorphism. That’s just when the males and females of a given species are morphologically different beyond just reproductive organs. 

Like how only male peacocks have the big frilly tail feathers. 

The anglerfish that comes up when you search it is actually female. Male anglerfish are many times smaller than their female counterparts, and don’t really look anything like their peers. Instead of reproducing, the male will embed itself into the female–and then all of its organs are basically dissolved in favor of turning the rest of its biomass into a sperm factory. 

Talk about codependency.

The Sperm Whale

Honestly they’re just kind of whales that can dive really deep. We just wanted to put them here to say you have a protector against the giant squid–since they fight. 

But it is pretty cool that sperm whales can go so deep and then come back up for air at all. Many deep sea creatures explode when brought up to the surface because air pressure only averages 15 pounds per square inch for us. Which is like 93 times less than the 1,400 pounds per square inch sperm whales deal with when they dive down to 3,280 feet.

Also they can hold their breath upwards 90 minutes.

Vampire Squid

We’ve listed a lot of really ugly weirdo abominations today, so here’s something that’s both alien and kind of beautiful. 

If you’re wondering why the vampire squid is named as such, it’s just because they look like they have a cloak and they’re red, they’re not known to drink blood. You might be thinking that red is a stupid color for living in a black environment.

Turns out, because red is the longest wavelength of visual light, it has a really hard time penetrating water. So when you’re thousands of feet deep, red might as well be “invisible.” Doesn’t help as much when we show up with our drones and flashlights, but you know. 

Giant Isopod

If you didn’t think giant squids were enough, say hello to the giant sea bug monsters known as giant isopods. Oh, and if you’re not scared of big sea bugs because they can hurt you, there exists footage of a giant isopod attacking a dogfish shark over the pithy scraps of food at the bottom of the ocean. Here it is.

Not the same kind, but still monstrous, is an isopod that literally eats the tongues of other fish. No that’s real, it eats their tongues and then becomes the new one.

Even though these are all crazy deep sea demon monsters we’d never want to see in our kitchens, it is quite sad that we’ve found plastic bags in the deepest parts of the ocean. Do protect our oceans, we haven’t discovered these alien monsters anywhere else.
