I kept them for years and also spent time working in Australia. The Aussies keep them by locale, and it is possible to confirm lineage. There are geographical intergrades that do not conform to strict color schemes.
As with womas and the various antaresia species, U.S. breeders often classify by looks - as, let's face it, these animals were all illegally smuggled out of Australia.
There are other ways to differentiate, namely a single pair of parietal bones in western populations as opposed to two or three in other populations. In terms of difference you can actually readily see, western specimens have fewer subocular and loreal scales.
I never knew that! I really appreciate you teaching me more about differentiating Black Headed Pythons locales by their scale counts . Also really cool to know you've raised some yourself and spent time in Australia with this wonderful species.
