Hm, that's interesting. "Jungle" presumably means Jungle Carpet (Morelia spilota cheynei). "Carpet" could mean any subspecies within Morelia spilota or any hybrid/intergrade of subspecies within that classification, and so is extremely non-definitive. If by "Carpet," they meant coastal carpet (Morelia spilota mcdoweli), then the 3 of them have basically come to the same conclusion as this thread: it's either a jungle, a coastal, or a jungle/coastal mix. No way to be conclusive w/o breeding/lineage records.
