I honestly think it should be left alone, on the ocean floor. because, if you preserve it and exhibit it, it's like taking a memory and messing it all up. if you just leave it, then you're leaving it where it should be. If you do preserve it, some rich person will just come along and ask to buy it with no thought in the story behind it, but only wanting it for it's beauty and fame. I know I'm only one person, But really. Leave it.
