The development of underwater robot imitates the locomotion and flow around a swimming fish since its manoeuvrability and efficiency is excellent. The work presented in this manuscript aimed to visualize the flow of a real fishtail to aid the design and fabrication of a mechanical fishtail. The flow across the tail of a Gourami fish when it was visualized and observed in a water channel under static water condition. The tail kinematics of the real fish were extracted and applied on the designed mechanical fishtail. The designed mechanical fishtail was employed to undergo the flow visualization experiment using Particle Image Velocimetry (PIV). The experiment was conducted with the flow in the water channel set at a velocity of 0.2�m/s while the mechanical fishtail was set to flap with an amplitude of 20�. Measurements were repeated with the tail flapping amplitude of 40�. Chain of vortices was observed to be generated by both real fishtail and mechanical fishtail. Through comparison, it is noticed that the flow pattern generated by the mechanical fishtail flapping with the amplitude of 20� has the highest similarity with the actual Gourami fish compare to the flapping amplitude of 40�. � Springer Nature Singapore Pte Ltd 2020.
