Black Child Reticulated Python. Blurb from New England Reptile Distributors website:
This dramatic looking version of the Golden Child is just plain awesome! We have once again spent micro seconds over the name and dubbed this one the “Black Child”, we only thought it made sense. This mutation was the result of breeding the Golden Child gene into the Calico gene and some how hitting a combo that caused the melanin gene to go into hyper drive. The animal appears sheer black with incredible blue iridescence. If the Super form of the Golden Child is an all Black snake, we will be ecstatic!
