Body resists soil adhesion: dung beetle

Body of the dung beetle reduces soil ahesion via non-smooth surface morphology.

"The adhesion forces of soil, which exist when soil is in contact with a solid interface, often make troubles for soil engaging components of vehicles and machines, such as earthmovers, excavator-buckets and bulldozers, and result in the fall of power output. However, the phenomena of soil adhesion disappear when soil-burrowing animals move in soil. Soil animals' such excellent ability of anti-adhesion is partly resulted from their non-smoothness surface morphologies [5], for example, the morphological body surface of dung beetle is of non-smoothness or roughness in micro scales, as shown in Figure 1."

Great example of Life's Principle "Fitting form to function" Has bumps all over body to prevent mud and manure from clinging to it. It has been mimicked in a bulldozer (!) to reduce the time lost cleaning equipment. Needs to have bumps to stay clean.
