Um well i may be new to BP's but i know that whatever study these people performed could not have linked the spider color pattern to the spider vision...I'm a bio major far along in my studies, just to give credibility not to brag. I have a spider and she does wobble a bit, i think its kind of cute, and honestly when i see her wobble it looks more like a muscular contraction because of some hormone release when excited about feeding or whatever. I highly doubt if not blatantly refuse that the spiders see their world as constantly spinning and wobble or twist as a result. Most likely this trait is connected to a slightly higher release of an excitatory hormone that occurs with this morph, which is a more sound explanation that can also be used to explain the reason that these snakes tend to be more curious and active, "tend to be." If it is just a hormone release trait, not problem, it is something that their bodies will grow and mature to control. Probably the reason most older older spiders stop their wobble.

Honestly when my snake Eva eats and she starts her wobble i play some music and i think she's just dancing, kinda how we dance when were excited.
