Could try turning the "fuzzy select" tool threshold down to 1. If the region actually has a different color index than the background, it will select it. If it's all the same then the select tools have no way to know where the edges were. If some other version of the skin exists with distinct areas, it could be inserted as a new layer at 50% opacity and it could be used for tracing a selection area.
