The remains of the Titanic could disappear in 15 to 20 years' time because bacteria is eating away the wreckage, German marine biologists say.
Antje Boetius, of the Alfred Wegener Institute for Maritime and Polar Research, says "the hull of the boat is covered in rust and [bacterial] organisms."
The harmful, which could destroy what is left of the Titanic, was actually discovered many years ago, according to Clarin.
The researchers believe it's actually too cold down at the bottom of the ocean for the bacteria to eat away what remains of the tragic ship.
Boetius said: "In reality, this bacteria grows where temperatures are registered above 30 degrees centigrade. And there, where the hull is situated, the temperature is only a few degrees."
Nonetheless, the researcher believes, the bacteria will eventually cause the internal walls to collapse.
"These bacterias don't eat away the surface millimetre by millimetre, but instead they subject the boat to a type of bite that makes the hull become increasingly unstable and disintegrate," Boetius said.
The ship lies 3,800 metres deep in the sea after it sunk in 1912 and killed around 1,500 passengers. Over a hundred years on it remains the world's most famous shipwreck, and a company is even planning to take tourists on a deep-sea tour of the wreck.
