In the field of animal propulsion in a fluid, be it the swimming of fish or the flight of insects or birds, the problem is driven by an active movement of the structure (e.g. wings, body, or fins) that generates the propulsive force. The structure is thus usually deformable under the action of the flow and strong fluid-structure interactions occur. I will give an overview of two experimental problems that we have studied at ESPCI Paris, aimed at understanding fundamental dynamical elements related to flapping wing propulsion and undulatory swimming: (I) Insect-inspired two-vein flapping wings with anisotropic rigidity; and (II) Waves in the wake of a surface swimming snake.
