CHOCOLATE Brazilian Rainbow Boa. What is the deal with these snakes ?? Who knows, I have a couple of these currently in my collection and as you can see this pair has all the characteristics of a typical Brazilian with one major exception..COLOR ! They have dark brown patterns on a lighter brown background coloration ?? One in the picture is "blue" the other has just shed. What a fun project. By pure definition they would be considered hypos i.e. reduction in the black pigment but these are something a little different.
