From: The mechanics of abalone crawling on sharp objects without injury
Abalone crawling on sharp blades. (a) Parallel blades aligned on the substrate. The insets show enlargements of the side view of the single blade indicated by the red box. The right inset shows the included angle as α = 13.6°, and the top surface of the blade is a rectangular area. (b) Bottom view of an abalone foot on the blades, which indented the sole by around 3 mm. (c) After removal from the blades, grooves about 2.13 mm deep remained on the sole. (d) Appearance of the abalone foot after several minutes. The grooves had disappeared.
