I'd really like to see test cases on this. I've never seen any of this in any of the spiders I've kept (from regular spiders to bees, etc). I have a vanilla killer bee right now that has a TERRIBLE corkscrew when he gets excited, ex. during feeding time. But he strikes fiercely, is fairly accurate (at least no less than a typical BP), swallows his prey down, evacuates on the regular. When I have him out he grips, he's curious... I see little to no behavioral or physiological differences between him and my plain, normal male BP. I have never seen any behavioral or physiological differences between any spiders I've kept and my normal BPs.

I don't have a large collection, so I think it would be interesting for someone to test this and track the differences, and then document said test cases. I haven't read the article you're referring to... did they do this? Or just paint in broad strokes?
