I heard an interesting theory on why spiders and spider morphs "wobble". Don't take this as fact, I posted it before and nobody on here had ever heard it before, but I heard this from a vendor at the last reptile show up here.

He was saying that he heard of a study that was done where they showed that spiders actually see everything as spinning constantly, which causes them to spin around to try to make the world seem upright. Supposedly as they get older they learn to either control the spinning or they just learn to work with it thats why most older spiders do not show as many signs of the dreaded "wobble".

I actually talked to Kara Glasgow up at NERD about the "wobble" when I got my spider from them and she was saying that the original spider which was brought in from Africa by them had the "wobble" and it's just been passed down through the many generations of spiders (I believe that that spider was one of, if not the original spider to be brought into the US).

My spider does "wobble" sometimes but it's not a violent thing, though I have seen other spiders who constantly spin and contort themselves in ways that I can't see being very comfortable or safe for the snake. Like your bumblebee my little guy is without a doubt one of the most outgoing, lovable snake that I own and I absolutely LOVE him .
