The sandfish (Scincidae: Scincus scincus) is a lizard capable of moving through desert sand in a swimming-like fashion. The epidermis of this lizard shows a low friction to sand as an adaption to a subterranean life below the desert's surface. Caused by material properties of β-keratin proteins forming the outer epidermis, this low friction reduces further adhesive wear. Both skin effects, the friction reduction and abrasion resistance outperform even steel. A possible explanation for these properties is an increased glycosylation of the β-keratins. In this study, the friction and...
