Vortex methods are an efficient and versatile way to simulate high
Reynolds number flows. We have developed vortex sheet methods for a
variety of flows past deforming bodies, many of which are biologically
inspired. In this talk we will present simulations and asymptotic
analysis of selected problems. The first is a study of oscillated and
freely-swimming flexible foils. We analyze the damped resonances that
determine propulsive performance. The second problem involves multiple
passive flapping ``flags" which interact through their vortex wakes. The
third problem is a study of flexible falling sheets. Here the
flag-flapping instability helps us determine the terminal falling speeds.
