 In the "" DVD commentary, writers Ted Elliott and Terry Rossio mention that the crew actually become less and less human until they are literally absorbed into the "Flying Dutchman" (Davy Jones knows this, but fails to inform new recruits).One character, Wyvern, is so transformed that he is now integrated into the ship's hull.The crew has little or no human flesh remaining on them, although newer members, like Bootstrap Bill, are only partially encrusted with sea life.
