Size can also be traits of some localities such as the proper small rainforest jungles such as Palmerston jungles all of which aren't necceserry black and gold.You also get some small highland animals such as the Julatten black and whites,the coastal fringe types can get as big as 6 foot and the Atherton jungles are the largest jungles some reported to be up to 10 foot long but to me and many others they aren't proper or true jungles. The small nervous,shy psycho rainforest types are true or proper jungles.There's an Atherton for sale on here and is a good 8-9 foot long.Athertons don't tend to be black aqnd yellow however you do get some stunning Athertons maybe SXR athertons are a good examples of big brightly coloured animals and I've seen a few other nice bright Atherton lines around also,pike1's are some of the best I've seen colour and especially pattern wise.
Jungles if you get right into them and their distribution along with neverending variety can be quite complex to explain and understand.They never cease to amaze me,one of the best looking Aussie pythons there is imo
