Basically the opposite of a leucistic ball python.
Albinism refers only to the reduction in melanin, where as Leucism refers to the reduction in all types of pigmentation.
Melanism refers to the increase in melanin, resulting in much darker pigmentation.
Following that thought..
Abundism refers to excessive amount of dark pigmentation.
Has anyone attempted or managed to breed an all-black ball python?
Is it at all possible?
