Cool snake, it is very coincidental/ironic who found it. I think it would be interesting to own and observe, but not any value to me as a breeder, because polycephaly is not genetic in terms of a heritable trait. It's just a malfunction event during embryo development. The snake may or may not have long term issues regardless of who's hands it is in anyway. There is probably something for science to learn from that snake, but he could donate it after it dies too. Granted maybe more could potentially be learned while it is alive in terms of internal organ structures and figuring out the mechanism by which it formed two heads. I think if I found it I would keep it for a while just for the fun of it all, but soon it would be boring anyway and no point in breeding, so I would probably do as Albert suggests and find someone in the scientific community that would want to study it.
If it were genetic and you could potentially make lots of them AND if they were without issue, it would be an awesome breeding project, lol, but that's not probably ever going to prove to be the case.
Recessive two headed gene... hahaha
I would much rather see the scalesless gene circulating in the garter hobby. I think there would be a lot of beautiful combos produced. Just looking at the scaleless found in Tennessee this summer, I can only imagine how crisp and bold the colors would be on a erythristic scaleless eastern garter, not to mention no scales is just plain cool IMHO.
I am just glad that with the internet and Facebook increased availability via phone more people have access and we all get to enjoy seeing these mutants surface. We saw a lot of new things found in the wild this past couple years. I suspect this happened in the past too, but was just not as widely publicized.
