Gravity sampling is of vital importance for sampling seabed sediments and understanding submarine sedimentary environments and resources. In this study, a new bionic sampler tube (BST) with non-smooth surface for low-disturbance and rapid sampling is presented. The BST with depressions and swellings on its surface was designed on the model of the non-smooth surface of the dung beetle. Sufficient theoretical calculations, numerical simulations, and experimental tests were carried out to study its sampling performance. The penetration depth, sample length, and frictional drag of the sampler tube were calculated. The finite element model and the coupled Eulerian-Lagrangian (CEL) method were used to analyze and compare its sampling performance. Laboratory and field gravity sampling tests were conducted and the results demonstrated the advantages of the BST in improving sampling performance and in reducing adhesion and drag.
