I'm sorry, I must be dense, but the articles seem to contradict one another. In one you say you are certain that your aberrant with just a black belly is a normal and in the other one you say that you are uncertain but you a pretty sure it's an anaconda even though it seems to have less anaconda properties than your first aberrant.
Also I don't think it helps to compare a super anaconda belly to either a normal anaconda or a black belly since it has been established by Brent already that super anaconda have different bellies than normal anaconda (blacker, narrower).
Here is Brent's comparison and there is a huge difference in super and normal anaconda bellies.

Have you bred either of your aberrants to anacondas yet?
I talked to Brent about my gal and he says that she has many of the qualities of an anaconda but needs to be bred to an anaconda and see if any supers are produced to know for sure.
I'm not willing to label mine an anaconda until she has been proven or disproven by breeding to an anaconda.
