Hi

I just hatched this juvenile today from a single egg litter. Any of you know if this is reported before by this species?

I reckon it is not genetically but how does it comes to this?

No, its not genetic, it is the result of incomplete twinning. Have you ever heard of siamese twins in people? Same thing here. I saw a show on siamese (conjoined) twins showing several points of joining together, but so far in reptiles Ive only seen two headed individuals.

The only problem may be difficulty feeding, and one head will be dominant over the other. They will always try to go their own separate way.

Typically in reptiles, this occurs due to environmental changes during the early stages of development, usually pre-lay.

I've seen pictures of siamese turtles, and one twintail snake, but it very well could've been doctored, as I've seen nothing of that snake since.

It will be a rare example if the snake survives, in most cases two headed snakes don't do well and die.

Yes, it is rare, mutations either work as environmental, or genetic. Although, I believe conjoined twins are not an environmental mutation but when the fertilized egg split to form twins it did not seperate fully.
I have seen some examples in turtles that really look like two animals joiner, not just two headed. One had a split halfway up and had 4 front legs and two heads, like two bodies merged into one.

Please give updates on this snake. Also, I have seen two cases were they did survive, in a western diamondback and in an amelanistic black rat snake so good luck.

bicephalism is a result of weak genetics kinda like a scaless snake, very interesting but not something to strive for if u have a serious breeding op goning on. but its not something that can be passed down like amelanism its more like down syndrom in people. good luck with the snake
