“…If the biological structure and model are geometrically similar and their motion is characterized by the same Reynolds number, then the ratios of the velocities and the forces in the fluid around the model and the real structure are the same (Loudon et al, 1994;Mead et al, 1999). Physical models also permit the morphology and the kinematics of the structure to be modified so that their consequences to fluid flow around the structure can be explored.…”

SUMMARYMany arthropod olfactory appendages bear arrays of hair-like chemosensory sensillae. Odor molecules in the fluid around the animal must reach the surfaces of those hairs to be sensed. We used the lateral flagellum of the olfactory antennule of the spiny lobster, Panulirus argus, as a system to study how the morphology, orientation, and motion of sensilla-bearing appendages affects the small-scale water flow within the hair array. We tested whether antennule flicking enables lobsters to take discrete odor samples by measuring flow fields through an aesthetasc array on a dynamically scaled physical model of a P. argus antennule. Particle image velocimetry revealed that the magnitude and duration of velocity through the aesthetasc array during the rapid flick downstroke is just enough to allow complete replacement of the fluid entrained within the hair array. The complex zig-zag arrangement of aesthetascs hairs, combined with their offset orientation along the antennule, generates flow velocities that are uniform along the length of the hairs. This increases fluid exchange during the flick and reduces the boundary layer thickness surrounding the hairs. The return stroke occurs at about a quarter the speed of the flick, but the velocity of the fluid between the aesthetascs is approximately 25 times slower. The retained fluid during the return stroke remains virtually unstirred and sufficient time occurs for odor molecules to diffuse to aesthetasc surfaces.

“…Advection-diffusion models using data from dynamically scaled physical models of mantis shrimp antennules indicate that odor molecules in filaments moving into the sensor array arrive at the surfaces of the aesthetascs within milliseconds (Stacey et al, 2003). In contrast, during the slower return stroke of the flick and during the stationary pause between flicks, the just-sampled fluid remains in a layer coating the sensors, and new, odor-containing fluid flows around rather than into the array of chemosensory hairs (Mead et al, 1999;Mead & Koehl, 2000). Thus, an antennule of a mantis shrimp takes a discrete sample in time and space of its odor environment only during the flick outstroke (Mead & Koehl, 2000, Stacey, et al, 2003.…”

“…In addition, they occur in many coastal habitats, with and without waves. The external and internal morphology of their chemosensors (located on their antennules) has been measured (Mead et al, 1999;Mead and Weatherby, 2002). We use Hemisquilla ensiguera californica because they are active at a cool room temperature, engage in tracking behavior in the flume and are relatively easy to collect and maintain in the laboratory.…”

“…Stomatopods (Mead et al, 1999), like many crustaceans (Snow, 1973;Schmitt and Ache, 1979;Reeder and Ache, 1980;Devine and Atema, 1982;Gleeson et al, 1993Gleeson et al, , 1996Steullet and Derby, 1997;Hallberg et al, 1997), sample their chemical environment by flicking their second preoral appendages (antennules) through the surrounding fluid. In stomatopods (and some lobsters), the asymmetry of the flick ensures that already-sampled fluid is cleared out, so that new odor-containing fluid can come into contact with the animal's chemosensors (Mead and Koehl, 2000;Goldman and Koehl, 2001;Koehl et al, 2001).…”

Many marine crustaceans use water-borne chemical cues in ecologically critical activities such as finding food, mates and suitable habitat, detecting predators and communicating with conspecifics (Caldwell, 1979(Caldwell, , 1982Ache, 1982;Atema and Voigt, 1995;Zimmer-Faust, 1989;Weissburg and ZimmerFaust, 1993, 1994;Weissburg, 2000). The act of following an odor plume to its source is called 'plume tracking'. In turbulent environments, odor plumes consist of fine filaments containing high concentrations of odor molecules interspersed with the surrounding fluid (Murlis and Jones, 1981;Moore et al., 1994;Weissburg, 2000;Crimaldi and Koseff, 2001;Crimaldi et al., 2002). Crustaceans sample the fine structure of the odor filaments by moving their antennules through the filaments . We are interested in discovering how mantis shrimp (and by extension, other crustaceans) use the information contained in odor filaments to find the source of the odorant.Initial studies of plume tracking relied on descriptions of plumes as slowly diffusing clouds of chemicals rather than as filamentous, intermittent and dynamic structures. By recording at a point, later investigators showed that odor plumes are intermittent (Zimmer-Faust et al., 1988a,b, 1995Moore and Atema, 1988, 1991;Atema et al., 1991;Moore et al., 1994;Consi et al., 1995;Dittmer et al., 1995). More recently, planar laser induced fluorescence (PLIF) techniques have shown that odor plumes in water are filamentous Webster and Weissburg, 2001;Crimaldi et al., 2002). Koehl et al. (2001) have shown how odor filaments are encountered by a real antennule swept through a realistic plume by computer-driven motor attached to a stationary lobster carapace. Our study examines odor encounter by antennules of a live, odor-plume-tracking stomatopod.In addition, earlier plume-tracking investigations focused on unidirectional flow. While some species inhabit environments exposed to unidirectional flow (e.g. crabs and crayfish), many others live in coastal habitats and thus experience wave-affected flow. Understanding plume-tracking algorithms requires accurate information about the odor signal encountered by the animal's sensors as it tracks a plume in an environmentally relevant flow field. Our goal in this paper is to answer, for the first time, the following question: what is the instantaneous, fine-scale chemical signal encountered by the mantis shrimp as it tracks an odor plume in wave-affected and in unidirectional flow? This information, correlated with behavior, is the critical first step in deducing the algorithms used by odor-plume-tracking animals. Mantis shrimp as model systemsWe use mantis shrimp (also called stomatopods) as a model
