James and JC,

Those are a couple of great replys with some real thought put into it, as well as good scientific thinking. In reality the Ghost San Felipe most likely has the upstream metabolic defect that JC proposed. "Hypopigmented" is a more accurate term, but honestly sounds like a disease or a bad date. LMAO

The working definition of hypomelanistic in the herp community refers to the reduction of black pigmentation only. "Ghost" may not be the right term either but does refer to a shadowing effect which is what we see in these boas. I can see why there may be sensitivities, because those rosy breeders currently doing a hypo x anery project will feel their prospects somewhat devalued by the alternative use of "ghost".
