Spider "Head Wobble": This term refers to a trait that virtually all spiders show. In most cases, a spider will show slight movement, or wobbling of the head when the snake holds its head off the ground. In more severe cases, the snake may seem to lose orientation when it is excited or agitated. Nearly all spiders showing this trait live normal, healthy lives. It seems that the trait is just something we have to live with to have this beautiful pattern in our collections.
