This ugly dude is all the scariest parts of a crab combined with all the scariest parts of a spider, and then made giant. No thank you!

Imagine being in the photographer's position as he took this photo. It would be absolutely horrifying!

The ocean floor doesn't just house creepy animals, but also some human waste. There's just something super creepy about investigating a giant abandoned submarine.

How is the woman comfortable over that abyss!?

For many people, sharks are one of the main reasons to be afraid of the ocean. Imagine swimming along and seeing this below the surface of the water!

Kayaking alone on the sea only to turn around and see a shark tailing you? Nothing could be scarier!

One of the more well-known of the ocean's scary deep sea dwellers is the anglerfish. Although it isn't large, with that face and creepy lit-up tendrils, it's definitely terrifying.

The goblin shark is a truly terrifying-looking deep sea dweller. Imagine having this swim out at you in the darkness of the deep sea.

There is so much unknown about the ocean, mainly because we can only go down so far into it. The deepest part of the ocean extends 11 kilometers down into a watery abyss. Imagine what horrors that deep darkness hides!

We have no idea what this is and we don't want to know! Just throw it back, please!

Seaweed is not threatening, but it can sure look super creepy when lifted by a wave. They look like tentacles!

This woman looks very zen for being a few feet from that gigantic stingray!

The water isn't too bad when you can see the ground, but when it disappears into a gigantic dark hole, that's not OK. Turn around! Head back for shore!

The ocean is home to the largest animals on earth; many of which we don't even know much about! Just the immense size of some of the creatures is enough to send someone into a panic.

Normally the water's surface shields us from having to see the ocean's terrifying depths, but that's not so of the clear water around this island. Look at that drop-off!

This is one of the only photos of a live giant squid. Able to grow to up to 43 feet, the giant squid is one of the largest animals in the world. You definitely don't want to run into one of them.

Imagine being that close to an animal that's at least ten times your size. He must have been scared!

Jellyfish are nothing to mess with, as even the really tiny ones can cause severe pain and even fatality! This gigantic lion's mane jellyfish is more terrifying to look at than it is harmful, as their stings just cause redness and irritation. You probably still wouldn't want to run into this huge thing though!

Nope, nope, nope! Turn around, sir.
