We discovered that they can go through three-millimeter gaps, the height of two pennies, two stacked pennies, and when they do this, they can actually run through those confined spaces at high speeds, although you never see it.
Hem descobert que poden passar a través de forats de 3 milímetres, l'alçada de dos centaus, un sobre l'altre. I quan ho fan, poden, fins i tot, caminar a través d'aquests espais confinats a gran velocitat, encara que mai els veiem.
