The Japanese Spider Crab

This crab gets its name honestly. The Japanese Spider Crab can be found in Japan, yet it has also managed to show up in other areas of Asia. Of course, they are incredibly unique. Due to that, you can find them in many aquariums all over the world too. You’d be forgiven for being thrown back a bit by their appearance. While this truly is a crab, the spider-like features make it much scarier. Worst of all, these creatures get to quite a large size too.

Japanese Tsunami

Japan is not just home to giant crabs, but they are also known for getting some pretty bad tsunamis too. Of course, many Asian territories such as the Philipines also deal with their fair share of them too. Tsunamis are unique events, and would likely make anyone anxious. Thus, you do not need thalassophobia to be afraid of them. This particular image shows giant waves destroying an area in Natori, Japan in 2011. Luckily, most of the area has recovered since this event.

The Oddly Dangerous White Sturgeon

Weirdly, the white sturgeon is one of the most dangerous fish species. The man in the image above is named Jeremy Wade. He is known for following mysteries or legends about monstrous sea creatures for his show River Monsters. Wade has caught several fish over the years, but one he keeps coming back to is the white sturgeon. They attack humans at shorelines constantly. Interestingly, they hop around in both freshwater & saltwater during migration periods when not land-locked.

Massive Whales that Can Appear and Disappear

Blue Whales are beautiful creatures. They are the largest animal of any kind in the world today and hold the record for being the largest mammal to ever exist. Seeing one in the wild is relatively rare unless you know exactly where they navigate throughout a given year. However, due to their size, seeing them show up while you’re on the water can be horrifying for some people. Especially if you have thalassophobia, and experience something that the people in this boat above dealt with.

The Dangers Of Rip Currents

Rip Currents are incredibly dangerous. While a riptide usually comes in via the ocean, affecting the waves on the water, rip currents come onto the beach. Due to breaking waves having to crash out somewhere, water ends up on a beach. Yet it then has to go back in, which can sometimes cause people to get caught in one and be sucked out to sea. Above you’ll see an amazing situation where people made a human chain to save swimmers caught in one of these rip currents back in 2019.

Fish that Can Camouflage

Flatfish are notorious for creeping people out when they go into waters around the world. They hide on the ocean floor to both avoid potential predators and catch their own prey. Pictured above are two turbot demersal flatfishes. You might assume they were fossilized based on how they look. However, they are merely in the sand just covered up, lying in wait. Flatfish are known for blending into an environment like this, so one could be right below you in the water and you might never know.

Underwater Fog

There are many places divers can go in the water. Sometimes, the water is a bit murky or very much so. Those waters can be eerie, but it is likely people with thalassophobia will be just as creeped out by the infamous “underwater fog.” This fog is pretty weird to see. We’re used to seeing it on the surface near water, but underwater it forms in a similar way. Complex interactions with ocean evaporation, atmospheric pressure, shore temps, etc. cause this to take place. It’s creepy regardless.

Cave Diving Horror

Cave diving, sometimes known as spelunking, is something many people love to do worldwide. Just going through and exploring caves can be pretty fun for people. Yet regular caves can be creepy to explore. Now add the underwater part to this exploration. Cave systems are known for being difficult to deal with. People get lost in them all the time and those are mostly just surface caves. Underwater versions could be horrifying, and may God help you if you’re lost or your equipment fails.

Underwater Rivers

Underwater rivers are quite jarring. The name, however, is misleading. The Cenote Angelita Cave you see above has one and displays the misunderstanding well. A halocline, or cloud of hydrogen sulfide formed by decomposed organic debris at the bottom of the cave, makes the saltwater separate from fresh groundwater. That groundwater comes from below and seeps into the saltwater. Making it appear to divers that they are swimming in an underwater river attached to an ocean source.

Volcano Eruption Underwater

If you know anything about the planet, you know we have volcanoes not just on land but also in the water. Of course, oceans have risen over millions of years. This means some volcanoes once high above land will not be partially or completely submerged. Yet they are still just as dangerous as other volcanoes. Being near one when it is erupting is possibly life-threatening. Moreover, these volcanoes give off enough energy to power cities as well as start-up tsunamis.

The Depths of the Ocean Holds Truly Bizarre Creatures

Some people with Thalassophobia have reported being weirded out by this little guy. It is known as a Mantis Shrimp, getting its name from its similarities to the Praying Mantis. While the species gets far larger than the insect as well as larger than many other shrimp species, it is still relatively small. Humans have come into contact with them many times and did not have issues, but some did. The infamous punch from this shrimp is painful, and attacks can leave humans with some bad injuries.

Octopus Attacks

Most will tell you that if you leave them alone, octopi will leave you alone. An octopus rarely ever goes on the attack, especially against humans. They can be territorial though, so getting too close might cause this. Other times, they might be a little angrier than humans expect. The man above experienced this the hard way. An octopus was not happy with him being there and decided to attack him, taking away his camera along the way. Must not be a fan of being put on video without permission!

How The U.S. Navy Drownproofs SEALs

The United States Armed Forces has some of the most well-trained, and toughest men and women on the planet. Yet it goes beyond just being able to handle a weapon or fight. Sometimes, you need to be prepared to avoid death. In the Navy, you’re put through a drown-proofing course. This is essential for Marines and SEALs who will likely be around the water a lot. They tie up your arms and legs and have you do specific things numerous times until you’re, well, drown-proof.
