Antennules of the spiny lobster trap water to identify odors using chemosensory hairs.

BIOMIMICRY TAXONOMY
Summary
"lobster olfactory antennules hydrodynamically alter the spatiotemporal patterns of concentration in turbulent odor plumes. As antennules flick, water penetrates their chemosensory hair array during the fast downstroke, carrying fine-scale patterns of concentration into the receptor area. This spatial pattern, blurred by flow along the antennule during the downstroke, is retained during the slower return stroke and is not shed until the next flick." (Koehl et al. 2001:1948)
