First, this 'morph' is a little more common than most of you think. I've been working with this morph for almost a decade now, and know of multiple others working with them as well.



The original female from whom the first 'anery' morphs came from was a standard wild-type zonata. It had a lot of black, but its red was red. When it was bred to another snake from the same locality two 'anery' female snakes were produced. During the first few years of breeding, the same pair only produced female 'anerys' (this was simply due to low sample size; at first it was thought it was a sex-linked trait, but that has since been proven untrue as multiple male 'anerys' have been produced). While the trait is apparently a simple-recessive, it does manifest itself differently within the sexes - but only in the red rings. Females tend to be born with lavender-gray rings instead of red. By most females third shed they are almost completely pure black and white (with the white in both males and females having a purplish-blue hue). Males, on the other hand, are born with pinkish rings instead of red, and tend to retain some of the ringing as adults (the pink slowly turns to a gray).



These are NOT your typical anerythristic animals. I don't know what they are, but I do know they are unique. Some populations of alterna are born tri-color and ontogenetically change to a bi-color animal in a very similar fashion (but the white in alterna is normal, where it is not in these guys).



Everyone that has these is highly secretive about their animals. But they are a lot more prevalent in collections than they might appear.



Below are examples of a typical male and female of this morph:
