I asked the same question myself when I first got the question, but when it means "Fully Submersible", it's fully submersible, whole heater unit, and the cord. The only part that can't be wet, is the plug itself.
Though it can happen, so far it has not happened to anyone that I know that a turtle would bite the cord, if you're uneasy, leave the cord out of the water, but it doesn't matter really.
Hey hey hey.
