Locomotion of flatfish
Animals like flatfishes intentionally produce vortices to bury themselves when a potentially dangerous situation like a predator is detected. To prevent themselves from being caught, this process has to be very fast. The flatfish induces vortices which raise sand from the ground which settles down on the fish and makes it invisible to its attacker. The investigation and understanding of the complete process using a living fish is quite challenging and thus it is still a pending task. According to the literature important questions to be answered are the three-dimensional motion of the surfaces of fish as well as the structure of the three-dimensional flow field induced by fish. Investigations on these points (besides others) will contribute to a better understanding of the locomotion of fish.
