Undoubtedly the most famous shipwrecks in history, thanks in part to a hugely successful film in the 1990s based on the sinking, the RMS Titanic was for a time the largest ship in history, and as a consequence the largest shipwreck. Despite its size, however, the whereabouts of the lost ocean liner were unknown for decades following its disappearance in 1912.
That changed in 1985, when the Titanic was found at a depth of 12,500 feet off the coast of Newfoundland. The shipwreck is composed to two large sections that drifted and settled about a third of a mile apart.
Because of its size and the state of deterioration of the vessel, raising it from the ocean's depths is prohibitively difficult. The Titanic also is now home to practically an entire underwater ecosystem, with a community of crabs, fish and bacteria now inhabiting its decks.
