The Spider Problem?

[snakesRkewl]

It seems to me that it is more often the males that are the more extreme examples of this "defect" Anyone else think there might be something to this?

nope, I have seen as many female spiders wobble as males.
I have also seen a female spider combo that has no head wobble produce babies that wobble, don't let anyone tell you that you can make non-wobbling spiders just because the male or female doesn't wobble, it's just not something anyone can guarantee.
