Reducing energy consumption and protecting the environment has always been becoming the pursing goal and object for mankind, especially in the past several decades. Our living environment is all surrounded by the fluids, and the friction in turbulence has progressively developed into the important proportion of energy consumption. Therefore, how to realize the drag reduction in turbulence has turned into the imperative issue to be resolved, and many scholars have made great contributions in the field with achieving so many profits. In this paper, three different typical biological functional surfaces including sharkskin, lotus leaf and dolphin skin are reviewed and generalized systematically and comprehensively, the drag reduction mechanisms based on boundary layer control are generalized. The paper will enable the potential readers to better understand the recent progresses in exploring drag reduction technologies in turbulence, with improving the comprehension of the drag reduction mechanism and extending the relevant technologies into more applications.
