200 shipwrecks rest near Cape Hatteras NC. Most are sailing ships, but others, about 70, are from WWII. Truk Lagoon in Micronesia holds more than 60 Japanese ships sunk during WWII. Corals, sponges and fish have taken over all the wrecks for their own. Preservation of the shipwrecks is also discussed.
