I agree with adam on this one. They all spin to some degree. I personally don't see how it can be considered any other than a defect. I know everyone always says they eat and breed fine, but they have not been around long enough to know if there will be any long term problems. No one knows if these snakes will end up living 40 years or die earlier than normal yet. I personally have chose not to work with them because of this defect. I think they are great looking snakes and the Lesserbees (check out the one John Piro is selling on KS it's insane) are one of my favorites but I have resisted buying any because of this. Maybe if someone figures out how to at least minimize this problem I would change my mind but I have seen some that were so bad that they pretty much layed coiled upside down 24/7.
