We get to know that Kongs family or maybe entire species is wiped out by the skull creatures. We saw their bones in skull creatures' territory. Only Kong the king left. Now skull creatures are a lot in numbers. But we just saw Kong himself. So is Kong alone? If so then in future, when Kong dies no one to protect from those creatures!! Cause Kong alone can't reproduce.
Is there any official explanation? What is the lifespan of Kong?
