We studied the small-scale hydrodynamics of diverse olfactory antennae of marine animals to elucidate ways in which their physical structure and motion affect how they encounter the concentration distributions in odor plumes, and to gain insights for the design of man-made chemical sensors. The designs and motions of the lobster, crab, and mantis shrimp antennules we studied enhance their ability to take temporally and spatially discrete odor samples. We also measured turbulent water flow at several types of coastal field sites, simulated such turbulence in a flume with Koseff at Stanford, and measured how the fine filaments of high concentration in a chemical plume are affected when antennules flick through them when an animal is different distances from an odor source.
