We still don't know that for sure. That would be quite big for the Sea Emperor. But maybe this was a Male Sea Emperor! Huh? Ever thought about that? Because the one that will be in the game is going to be a female. So maybe this is the size of a male! But that is not still confirmed. For me the skeleton will be "The Lost River Leviathan".
