Seeing the huge variety in color and pattern of certain captive animals (like ball pythons) makes me wonder if there are genetic mutations in reptile species (like albino, etc.) that has been seen, or caught (more than once) in the wild and were thriving.

I've heard of pied ball pythons being found in the wild, that were apparently thriving, but what else? What about an albino cobra, or a hypo burmese?
