The Guizhou Gastromyzontidae showed extraordinary normal adhesion and anisotropic friction on wet and slippery surfaces in the torrential stream. In this paper, we firstly characterized the composite microstructures of adhesive disc of the Guizhou Gastromyzontidae by using the Scanning Electron Microscopy（SEM）. Microstructures such as the hexagonal pad-like unculi, setae arrays and micro-pores were observed to cover the fin rays of the fish. Then, inspired by the surface structures, the adhesive discs with surface microstructures were designed and fabricated by using the 3D printing and molding technology. The regular disc with no surface microstructures was also fabricated as a control sample. The adhesion properties of the bio-inspired disc samples were investigated in water condition on substrates with various roughnesses. The results show that the artificial adhesive discs with composite microstructures have good normal adhesion properties in water condition. The artificial disc can broaden the applications of bionic underwater robotics.
