The UN estimates that there are some 3 million shipwrecks...lying on the oceans' floors.
And...there are dozens more...stranded in harbors...and on beaches around the world...including the infamous cruise ship Costa Concordia...in Italy.
Below...is a haunting foto of an old ship carcass in the harbor of beautiful and remote Baracoa, Cuba.
But...the cause of its demise is not shared...or perhaps...even known by locals.
