With the continuous development of bionic technology, human beings have made breakthroughs in obser-vation and simulation modeling of amphibians such as flying fish, Uria aalge, Gannet, and flying squid. On this basis, the field of aquatic unmanned aerial vehicle (AquaUAV) has also developed rapidly, but there are still some key technical difficulties. According to the types of bionic organisms, this review summariz-es the studies of the AquaUAV prototype, as well as the progress made in the wing structure, water/air propulsion method in recent years. Then, from the perspective of computer simulation and experiments, the research methods used in the study of kinematics and dynamics are analyzed. Finally, combined with the development status of this field, some key technical challenges are summarized and the future of AquaUAV is prospected.
