I don't believe the wobble head is due to inbreeding as spiders are dominate. If their genes were recessive I could see this a bit more, but as you can breed a spider to a normal and get spiders, they are less likely to be inbred in my opinion.

Also where someone said most respectable breeders would choose not to breed to not pass on the trait. One of the issues with spiders is that you can have two parent spiders that have a HORRIBLE problem with spinning or wobbling and the babies be fine, then you can take two seemingly non-spinning parents and breed and get spiders that spin horribly.

It's simply an issue with the spider gene. Some choose not to breed them, some do. It's personally don't think it's a major issue and will not choose to leave spiders out of my breeding plans, especially since most that I know who are choosing to leave out spiders, do so by instead supplementing pinstripes, which I don't like as much.

I don't have enough experience to decide if ALL spiders have this, or just some. There is a theory around that all spiders have this to some extent or another. Here's Adam from 8 Ball Pythons take on the subject: http://forum.8ballpythons.com/blog/?p=5

Either way, if you like them, breed them, if not, don't. Personally I just don't see it as a big enough reason not to use them in my collection.

My only question for Adam and some of the other big breeders. Has it been noted that the spinning in spiders is also apparent in the crosses (aka the different bees and such?) I've looked this up and haven't been able to find any information on this.
