We show that the a vortex (eddy) is generated at the leading edge of the fish tails and stingray wings. This leading edge vortex (LEV) creates a low pressure region in front of the tail/fin that enhances thrust generation by the tail/fin. This can inspire a new generation of propellers that use the LEV to enhance thrust production.
