The Titanic tragedy has been immortalised in the form of its shipwreck which people can visit via a submarine, but there's a reason no remains have been found.
The sinking of the ‘unsinkable’ ship happened in 1912, 112 years ago when it collided with a giant iceberg in the Atlantic Ocean.
Over 1,500 people died that night and those who survived were changed forever.

But even though so many people perished aboard the boat, not one body has ever been found in the wreckage.
Not a bone has been spotted, even by film director James Cameron who has visited the site 33 times and claims to have spent more time on the ship than its own captain.
The director was the creative genius behind the 1997 film of the same name which starred the likes of Leonardo DiCaprio and Kate Winslet.
However, not even the film guru could see any remains.

He told the New York Times in 2012: “I’ve seen zero human remains.
“We’ve seen clothing. We’ve seen pairs of shoes, which would strongly suggest there was a body there at one point. But we’ve never seen any human remains."
So, why hasn’t any bones been found?

There are a few reasons why it could be that there is no evidence of the dead onboard the boat.
Life jackets
Even though it’s widely known that there were nowhere near enough life jackets or boats for those in the ship, a lot of people still managed to wear one.
This means that they were still floating when they froze to death in the Atlantic.

When a storm happened right after the sinking, they could have been swept away out to sea for weeks or months until they broke down into nothing.
The depth
Bones have been found on shipwrecks around the world, and a lot older than the Titanic.
Many believe that the reason the Titanic has never had bodies on it is that there are deep-sea scavengers who immediately came to pick apart what they could find on the ship.

There are 43 species of shark in the Atlantic Ocean that the NOAA Fisheries manage, however they do say that it’s extremely unlikely that a swimmer would encounter one in that side of the ocean.
But the sea floor could be a different story.
Composition of the water
It could also be down to the chemical composition of the seawater - which changes as you descend into the depths.
Deep sea explorer Robert Ballard, who first discovered the Titanic's wreck in 1985, explained that below a certain depth, water actually dissolves bones.
He said: "The water in the deep sea is under saturated in calcium carbonate, which is mostly, you know, what bones are made of.
"For example, on the Titanic and on the Bismarck, those ships are below the calcium carbonate compensation depth, so once the critters eat their flesh and expose the bones, the bones dissolve.
"Now in the Black Sea, because there's no critters to eat, the bones should not be exposed. So, you should have perfectly mummified fossils."
