When you dip your toe in the water you are no longer at the top of the food chain.

Most of the plastic pollution in the ocean is not from straws, shopping bags, or consumer items as most of us were led to believe. It’s from fishing nets and fishing gear.

Only 5% of the entire ocean in the world has been discovered, that means that there is still 95% unmapped.

When a whale dies, it creates a whole new ecosystem

"Hot tub of despair" is a lake under the ocean, in the gulf of Mexico. It is highly concentrated with salt and has dissolved methane. Any creature that enters dies.

I’m a scuba diver and one thing that really scared me when I first started off diving, you hear SO MUCH more underwater then you ever will above on the surface, I’m not even talking about like the shifting or just the water itself moving, your hear things like fish clicking and other things like that, cuz underwater sounds move and travel a lot more so you hear a lot more and much quicker, was pretty out of nowhere when I first went under

Lost sailors in the sea who cling to wreckage basically have their skin dissolved by salt water after soaking for more than 3 days.

The largest biomass migration takes place every night when deep sea animals come up to feed

There are perfectly-preserved shipwrecks from ancient Greece preserved at the bottom of the Black Sea. The water is so deep that it becomes anoxic (oxygen free), which preserves organic materials like wood. Shipwrecks are cool, but I find the phenomenon a little disturbing, since there is probably no life down there.

I tell new scuba divers this: The ocean doesn’t care about you. It’s not actively trying to kill you. But it will do a lot of things on its own that will absolutely kill you if you’re not prepared and paying attention. I realize this could apply to any natural environment but it feels much more apt when talking about the ocean. One wave that you weren’t prepared for can make your day pretty bad. For the ocean it’s just business as usual.

The ocean is blue because all the other pigments are absorbed. So after a certain distance down everything thing becomes a monotone blue color, unless you have some other light source. The freaky part is if a diver gets cut underwater the blood looks black, like ink. All the red has long since been absorbed so there’s no wavelengths left to show you a red color when you bleed.

Ocean Acidification. Increasing concentrations of atmospheric carbon dioxide (CO2) lead to higher concentrations of dissolved CO2 in surface seawater. This results in ocean acidification, which may affect the growth of the photosynthetic phytoplankton that form the basis of marine food webs. So, total marine ecosystem collapse due to greenhouse emissions, the ocean produces more than half of the oxygen on earth, so that doesn't bode well for us.

We don't really know whats it in I can say that for thousands of years we drew sea monsters beliving they lived in it. Surprising alot of stuff we found in those pictures were in the ocean. (Giant Squid recently ). Just makes you think what else is actually down there that we don't know about.

There are parts of the ocean which are dead no oxygen in the water which means nothing can survive, no fish no plankton nothing at all. They are spreading exponentially. Whilst they are tiny now and have been. At the rate of growth. They’ll cause serious problems before the end of the century.

There are more viruses in the ocean than there are stars in the Milky Way.

94% of the Earth's oceans are just pitch black darkness.

The Mauna Kea Volcano in Hawaii is the both the tallest Undersea mountain and the tallest volcano Hawaii. It sits 6000 meters below the surface of the ocean and stands a staggering 4000m above. Giving it an overall height from ocean floor to peak of 10,000m.

If you commit suicide by jumping off a ship in deep water you will never be found, happens often enough on cruise ships, in those warm waters you'll be nibbled away before you gain buoyancy and return to the surface

Point Nemo is the most isolated place in the world. It's in the middle of the South Pacific gyre, which is a massive rotating current that basically keeps any nutrients rich water from ever getting in. So there is no sea life anywhere to be found except for a few crabs and bacteria that live near some thermal vents on the ocean floor. It's so far away from any land that if you sailed there the closest people would be on the international space station. This is the location HP Lovecraft was describing when he provided the location of R’Lyeh where Cthulu and the other old ones love, although Lovecraft's coordinates were slightly off. And in 1997 the loudest unidentified underwater sound ever recorded, known as "the bloop", originated near there. It was loud enough that it was recorded from multiple sensors 5000 miles apart and lasted for over a minute. The prevailing theory is that it was ice cracking off the south pole but we don't actually know what caused it for sure.

When sea creatures die in the ocean and their bones sink to the deep ocean floor, zombie worms eat the bones. The skin secretes an acid dissolving the bones, digesting the remaining fat and protein left behind.

It doesn't hate you. It doesn't love you. It doesn't even know you exist. When it destroys/capsizes your boat your boat didn't even cause a change in its movements. I am a sailor and I am in love with a cold heartless b***h who couldn't care less whether I live or die.

The sonar we use for deep sea mapping really screws up a number of species especially whales, dolphins and porpoises. Imagine walking around and a tornado alarm decibel-level noise triggers right next to you. We do that every time we use that high-powered sonar and it basically f's up their own sonar abilities causing them to be unable to communicate and navigate.

The fact that scientists think we have discovered more of outer space than we have of the oceans just scares me considering we don’t even know how big our universe is

Dolphins will r*pe almost any living thing, including humans. They do thus so much to the point where sharks are scared to go near them. Also Whales don't die of old age Rather, as they become older, their muscles become weaker causing them to not be able to swim and, as a result, drown, meaning that it's almost impossible for a whale to die of old age

Each ocean is a mass gravesite and we all go swimming in it and some of us end up in it

Just one millilitre of coastal water taken from the ocean's surface can contain up to 10 million viruses. The number of viruses decreases further offshore and deeper into the water.

Its well known but I feel like people just disregard how much stuff we've lost in the ocean. Like important pieces of history, military ships, planes, PEOPLE. And it's not just recent history? Like we still are finding ancient ships and mechanical things, skeletal remains and so on. That and all the statues and cities and things we've found sunk is incredibly terrifying. Because we just didn't know they were there? Like not including the things we haven't explored in the ocean that's native to the ocean, we have so much stuff to find in there. Like we still *technically* don't know what happened to Amelia Earhart. We think we found what might've been her remains on an island but we don't know if that was her or not. And where's her plane? Not to mention that while we have no clue how common it is people dump bodies in the ocean. Like. The ocean is a massive graveyard for bodies, vehicles and history.

90%of the sea-biomass is located in the deepsea, and 60% of the deep sea biomass is only lantern fish

Blue Whales cum 20 liters of sperm each time they ejaculate.

I remember watching a YouTube interview with a military diver. He described how when you’re doing a covert op you spend a lot of time just underwater doing nothing with no lights on until it’s time to move. He specifically mentioned how he had to get used to having large things bump into him in the pitch black.
