I will have to disagree with it being 100% myth, we just simply don't know.

We haven't seen a dead animal besides one claim that I know of, http://www.reptileradio.net/ball-pyt...tml#post775644 and one claim out of many breedings that have been done doesn't have me convinced yet, even if the homozygous rarely goes full term, you think there would be more than 1 by now.

There hasn't been a proven homozygous spider and honestly I haven't heard of an attempt to prove one out, let alone the multiples attempts it would take to even make a claim of it being lethal or say it doesn't exist. People use the lack of evidence as evidence of it being lethal which is ridiculous imo. If no one is looking for it and enough time goes by, apparently it just dies all of a sudden......

As for a breeder who has done spider x spider breedings personally, here you go: http://youtu.be/-fhnR5YdGdI?t=1m

how ever I personally feel he doesn't give us any more information, I haven't heard of his attempts (if any) to prove out a homozygous spider, so we are still in the same boat of "we don't know"
