I would have to agree with John...
You might have a beautiful boa that is super aberrant that may look just like a Jungle or even better than some of the Jungles out there. Does this necessarily mean it's a Jungle Boa...no. Does this mean it isn't a Jungle Boa...no. The chances of you lucking out and picking up a Jungle for FAR less than $3000 are slim...but not impossible since very little is really impossible. Who knows...maybe you did happen to luck out...BUT (and this is a BIG but)...the only way to prove your boa out as a Jungle is to spend a few years breeding it out.
You need to prove out the bloodline before you try to sell it or any of its offspring as GENETIC Jungle Boas. Remember, there is much more to a Jungle Boa than only abberant patterns. And from what I've been told by others as well as what I've seen from photos, you can pick out Jungle Boas from normal Boas in a litter of slimy babies like you can Albinos from Normals. It is a very distinct difference yet ironically, it is hard to describe.
I believe there are three main things to look for in Jungles. First of all, pattern. The abberancies that people seem to think are the only markers. The cookie cutter shaped saddles and connected saddles. NOT necessarily blocky saddles...slight distinction here.
Second, the tail. Jungles tend to have elongated tail saddles with high contrast between the red saddles and the base body color.
And thirdly, body coloration in general. Jungles tend to be much more yellowish in body color than normal boas; even when they brown over as they get to be adults. They have a very yellowish-brown look to them.
Now if your snake has all these characteristics and you truly think it's a Jungle Boa...start doing the leg work! Breed him/her to a normal, completely unrelated, boa and see what you get. If you get a litter where several of the babies are abberrant...Great! BUT (there's that but again), you're not done there.
Take one of those abberrant babies you just produced and breed it back to your Jungle. Or breed two fo the abberrant babies together. What did you get from that breeding? You SHOULD get some SUPER Jungle Boas. If you did, then congrats, you've got a Genetic Jungle Boa from the Swedish line. Many people seem to forget about the SUPER Jungle Boas...maybe because there are so few of them.
It's a lot of work. In my opinion, it's all absolutely necessary if you want to call and market your animal as a Jungle Boa but you are unsure of the exact lineage of your animal. PROVE IT OUT! Prove it out beyond a doubt and nobody will doubt you! That's how the swedish line of Jungles came to be...it tooks years of work but look how much they are worth!
A lot of people think they've got something special. I don't blame them because we all love our animals and whether you've got a normal Colombian Boa or a Super Jungle Hypo Boa...you've got something SPECIAL! However, we need to warrant the prices we ask for our animals. You have to show people that you have a very good reason for pricing your animal the way you did...none of this "It LOOKS genetic" stuff.
The above are (mostly) just my opinons...take them how you may. I will now step off my soapbox and allow the next person in line to take my place LOL!
I hope some of this was helpful
