Do Tarantulas Shoot Sticky Silk Webbing Out Of Their Feet?

“The history of science has plenty of examples which teach us that our present truths are provisional. But in my opinion the present evidence shows that tarantulas do not produce silk by their feet.”
 — That’s what University of the Republic in Uruguay entomologist Fernando Pérez-Miles says. But other people who do experiments with spiders and look at their feet through high-powered microscopes disagree! People like Stanislav Gorb and Claire Rind disagree. Who is right, who is wrong? We don’t know. But you probably wouldn’t want to sleep over any of their houses.
