Zombies are immortal (unless they are crushed with huge stones like in OST in Battle of Fountain) but Blackbeard isn't immortal and non of his human crewmen are immortal.
 * A little off-topic, but I have to say that is another small beef I had with On Stranger Tides. In the script, it was written that the zombies decomposed as Blackbeard himself died, while in the film, you only see Gunner and Quartermaster get crushed(not sure if it happened to Master-at-Arms or Yeoman though; I never saw them). But luckily, the fact that there were likely more that 4 zombies, and none were aboard the Revenge when Barbossa became captain, we can assume they decomposed as well.
 * Now back the scheduled blogging. lol xD
