Ocean Off Hawaii Filled With Wreckage:

"The Mahi, a scuttled Navy minesweeper off the Waianae Coast, has grown into a 190-foot artificial reef that is home to corals, leaf scorpion fish, pufferfish, triggerfish, eels and magnificent eagle rays. The nearby LCU, a 100-foot landing craft utility ship, houses two timid white-tipped reef sharks that flee when divers approach."
