“…In contrast, the rod that we used for zebrafish operated at a scale (Re AC = 8 for 50 Hz) where viscous forces play a substantial role in the flow field. Consistent with this idea, we did not observe the 1/r 3 attenuation in flow velocity with distance predicted in the far field for a dipole stimulus (figure 6) (Kalmijn 1988). Unlike the flows of an inviscid dipole, viscous flows are altered by their interaction with the body (Rapo et al 2009, Windsor andMcHenry 2009).…”

“…The radius of the vibrating sphere used in previous experiments (a = 3 mm) (Coombs and Conley 1997a) was 20 times that of the rod that we used for zebrafish (a = 150 µ m). This means that the sphere in the sculpin experiments operated at a regime (Re AC = 3, 180 for 50 Hz) where viscosity may be neglected and the sphere may be modeled as an inviscid dipole (Kalmijn 1988). This dipole model successfully predicted the spatial pattern of microphonic potentials by the hair cells of CNs (Ćurčić-Blake and van Netten 2006) and the extracellular action potentials from the lateral line nerve (Coombs andConley 1997b, Goulet et al 2008).…”

Canal neuromasts enhance foraging in zebrafish (Danio rerio)

Aquatic animals commonly sense flow using superficial neuromasts (SNs), which are receptors that extend from the body's surface. The lateral line of fishes is unique among these systems because it additionally possesses receptors, the canal neuromasts (CNs), that are recessed within a channel. The lateral line has inspired the development of engineered sensors and concepts in the analysis of flow fields for submersible navigation. The biophysics of CNs are known to be different from the SNs and thereby offer a distinct submodality. However, it is generally unclear whether CNs play a distinct role in behavior. We therefore tested whether CNs enhance foraging in the dark by zebrafish (Danio rerio), a behavior that we elicited with a vibrating rod. We found that juvenile fish, which have only SNs, bite at this rod at about one-third the rate and from as little as one-third the distance of adults for a high-frequency stimulus (50 < f < 100 Hz). We used novel techniques for manipulating the lateral line in adults to find that CNs offered only a modest benefit at a lower frequency (20 Hz) and that foraging was mediated entirely by cranial neuromasts. Consistent with our behavioral results, biophysical models predicted CNs to be more than an order of magnitude more sensitive than SNs at high frequencies. This enhancement helps to overcome the rapid spatial decay in high-frequency components in the flow around the stimulus. These findings contrast what has been previously established for fishes that are at least ten-times the length of zebrafish, which use trunk CNs to localize prey. Therefore, CNs generally enhance foraging, but in a manner that varies with the size of the fish and its prey. These results have the potential to improve our understanding of flow sensing in aquatic animals and engineered systems.

“…A lateral line comprises arrays of mechanoreceptive units called neuromasts. Each neuromast consists a bundle of sensory hair cells encapsulated in a gelatinous cupula [17] . There are two types of neuromasts, superficial neuromasts that stand on the skin, and canal neuromasts that are located in fluidfilled canals below the skin surface.…”

As a flow-sensing organ, the lateral line system plays an important role in various behaviors of fish. An engineering equivalent of a biological lateral line is of great interest to the navigation and control of underwater robots and vehicles. A vibrating sphere, also known as a dipole source, can emulate the rhythmic movement of fins and body appendages, and has been widely used as a stimulus in the study of biological lateral lines. Dipole source localization has also become a benchmark problem in the development of artificial lateral lines. In this paper we present two novel iterative schemes, referred to as Gauss-Newton (GN) and Newton-Raphson (NR) algorithms, for simultaneously localizing a dipole source and estimating its vibration amplitude and orientation, based on the analytical model for a dipole-generated flow field. The performance of the GN and NR methods is first confirmed with simulation results and the Cramer-Rao bound (CRB) analysis. Experiments are further conducted on an artificial lateral line prototype, consisting of six millimeter-scale ionic polymer-metal composite sensors with intra-sensor spacing optimized with CRB analysis. Consistent with simulation results, the experimental results show that both GN and NR schemes are able to simultaneously estimate the source location, vibration amplitude and orientation with comparable precision. Specifically, the maximum localization error is less than 5% of the body length (BL) when the source is within the distance of one BL. Experimental results have also shown that the proposed schemes are superior to the beamforming method, one of the most competitive approaches reported in literature, in terms of accuracy and computational efficiency.

Summary:The sagittae otolith morphology of marine fishes has been used in many ecomorphological studies to explain certain ecological adaptations of species to habitat. Our study compares the sagittal otolith shapes of ten species of snappers (Family Lutjanidae) inhabiting the Persian Gulf. We used a morphometric analysis of the otolith measurements (length, height, perimeter, area and weight) and of the ratio between the area of the sulcus acusticus and the area of the otolith (S:O). The otolith contour was also analysed using wavelets as a mathematical descriptor. Morphological variations in the otoliths were associated with the morphology and external colouration of snappers as well as ecological traits. An analysis of the interspecific S:O ratio suggested that the highest ratios occurred in snappers inhabiting shallower waters. A categorical multivariate analysis, including morphological, ecological and otolith size factors, showed that the species adapted to dim light conditions had a greater otolith perimeter. An analysis of variance of the otolith contour revealed zones with a higher interspecific variability, although only the antero-dorsal zone showed differing patterns. Although the otolith patterns appear to have a phylogenetic component, they might also be related to diel activity rhythms or to the light conditions in the habitat. The results of the study showed that variation in otolith morphology can be used to explain the coexistence of sympatric species.Keywords: otolith; morphology; biodiversity; functional ecology; snappers; Lutjanidae.Una aproximación a la comprensión de la coexistencia de pargos (Lutjanidae) a partir de la morfología del otolito Resumen: La morfología del otolito sagitta de peces marinos se ha empleado en estudios de ecomorfología al objeto de explicar las adaptaciones ecológicas de las especies al hábitat. Nuestro estudio compara la forma del otolito de diez especies de pargos (familia Lutjanidae) del Golfo Pérsico. El análisis morfológico se realizó a partir de medidas del otolito (longitud, anchura, perímetro, área y peso) y la proporción entre el área del sulcus acusticus y del otolito (S:O). También se analizaron los contornos de los otolitos mediante descriptores matemáticos denominados wavelets. Las variaciones morfológicas en los otolitos se asociaron a la morfología y la coloración externa de los pargos, así como a diversos caracteres ecológicos. Las especies con valores más elevados en la proporción S:O habitan en aguas someras. El análisis multivariante categórico de factores, ecológicos y morfológicos del otolito (forma y tamaño), puso de manifiesto que las especies adaptadas a condiciones tenues de luz presentan el perímetro del otolito más grande. El análisis de varianza del contorno del otolito reveló la presencia de zonas con gran variabilidad inter-específica, si bien solo la parte antero-dorsal permitió distinguir patrones claros de variación. Aunque dichos patrones parecen tener un componente filogenético, también estarían relacionados con el ritmo de activ...
