Abstract: On-the-spot observation, analysis and taxonomy for geometric nonsmooth animal surface shapes is one of the important links for adhesion and resistance reduction of nonsmooth surfaces in bionic research. In terms of different geometric nonsmooth surfaces, an extensive taxonomic research on typical nonsmooth animal surfaces has been made by use of scanning electro-microscope based on thorough observation and extensive collection of soil animals in sticky soil. An initial investigation on the forming mechanism of nonsmooth surface is also made in view of ecology.
