I understand that the temperature that your eggs are incubated at determines the sex of the hatchlings, and any temperatures to far outside this fine thermal region causes death. But occasionally the embryo survives and the animal hatches with birth defects.
Can anyone tell the reason behind have birth defects in a viviporous animal? Such as this emerald boa we caught in Peru. |

Most birth defects don't go full term and are either re-absorbed or aborted. |

There is no reason why a snake without eyes should not live well in captivity. I have heard of some doing quite well.

It was a shocking feeder and ended up dying. I have close to no doubt that it was caused by high temperatures early on in incubation. A fair proportion of that clutch didn't hatch and some of those dead embryoes had one or both eyes missing.
