Marine crustaceans with hairy appendages: Role of hydrodynamic boundary layers in sensing and feeding
Decapod crustaceans have appendages with an array of rigid hairs covered in chemoreceptors, used to sense and track food. Crustaceans directly influence the flow behavior by changing the speed of flow past the hairy surface, thereby manipulating the Reynolds number (Re). Hairs act either as a rake,...

| description | Decapod crustaceans have appendages with an array of rigid hairs covered in chemoreceptors, used to sense and track food. Crustaceans directly influence the flow behavior by changing the speed of flow past the hairy surface, thereby manipulating the Reynolds number (Re). Hairs act either as a rake, diverting flow around the hair array, or as a sieve, filtering flow through the hairs. In our experiments, we uncover a third transitional phase: deflection, where the flow partially penetrates the hair array and is deflected laterally. We develop a reduced-order model that predicts the flow phase based on the depth of the boundary layer on a single hair. This model with no fitting parameters agrees very well with our experimental data. Additionally, our model agrees well with measurements of both chemosensing and suspension-feeding crustaceans and can be generalized for many different geometries. ©2019 American Physical Society. |
