“…CNs are embedded in fluid-filled canals connected to the ambient water via small pores [20,21]. Consequently, CNs detect fluid motions inside the canal caused by pressure gradients between adjacent canal pores [22].…”

“…Although the canal structure already excludes the contamination of the sensors with particles larger than the canal pores, an additional segregation by means of flexible membranes covering the canal pores may further improve the lifespan of the sensor. Lateral line canals whose pores have a membranous covering also occur in some fish species [20].…”

Micro-Machined Flow Sensors Mimicking Lateral Line Canal Neuromasts

Fish sense water motions with their lateral line.The lateral line is a sensory system that contains up to several thousand mechanoreceptors, called neuromasts. Neuromasts occur freestanding on the skin and in subepidermal canals. We developed arrays of flow sensors based on lateral line canal neuromasts using a biomimetic approach. Each flow sensor was equipped with a PDMS (polydimethylsiloxane) lamella integrated into a canal system by means of thick-and thin-film technology. Our artificial lateral line system can estimate bulk flow velocity from the spatio-temporal propagation of flow fluctuations. Based on the modular sensor design, we were able to detect flow rates in an industrial application of tap water flow metering. Our sensory system withstood water pressures of up to six bar. We used finite element modeling to study the fluid flow inside the canal system and how this flow depends on canal dimensions. In a second set of experiments, we separated the flow sensors from the main stream by means of a flexible membrane. Nevertheless, these biomimetic neuromasts were still able to sense flow fluctuations. Fluid separation is a prerequisite for flow measurements in medical and pharmaceutical applications.

“…Lateral line neuromasts are known to be directionally sensitive and in teleosts the axis of maximum sensitivity corresponds with the long axis of the sensory strip (Coombs et al, 1988;Coombs and Montgomery, 1994;Janssen et al, 1987;Webb, 1989).…”

Anterior lateral line nerve encoding to tones and play back vocalisations in free swimming oyster toadfish, Opsanus tau

In the underwater environment, sound propagates both as a pressure wave and as particle motion, with particle motion dominating close to the source. At the receptor level, the fish ear and the neuromast hair cells act as displacement detectors, and both are potentially stimulated by the particle motion component of sound. The encoding of the anterior lateral line nerve to acoustic stimuli in freely behaving oyster toadfish, Opsanus tau, was examined. Nerve sensitivity and directional responses were determined using spike rate and vector strength analysis, a measure of phase-locking of spike times to the stimulus waveform. All units showed greatest sensitivity to 100 Hz stimulus. While sensitivity was independent of stimuli orientation, the neuron's ability to phase-lock was correlated with stimuli origin. Two different types of units were classified, type 1 (tonic), and type 2 (phasic). The type 1 fibres were further classified into two sub-types based on their frequency response (type 1-1 and type 1-2), which was hypothesised to be related to canal (type 1-1) and superficial (type 1-2) neuromast innervation. Lateral line units also exhibited sensitivity and phase locking to boatwhistle vocalisations, with greatest spike rates exhibited at the onset of the call. These results provide direct evidence that oyster toadfish can use their lateral line to detect behaviourally relevant acoustic stimuli, which could provide a sensory pathway to aid in sound source localisation.

“…Neuromast lines may consist of single neuromasts located at the bottom of shallow pits (pit-lines), in grooves of the epidermis (grooves lines) or enclosed in canals (canal lines) (Coombs et al 1988, Northcutt 1989, Arratia & Huaqufn 1995. Small pits on the surface of head bones of some fossils have been interpreted as pits for neuromasts .…”

“…In contrast, the neuromast pits in the new species from Tendaguru are distributed in lines (e.g., parietal line, subopercular line) and are scarce or absent in the operculum . The comparison is limited due to missing information for most species of Lepidotes, and that the development of neuromasts shows ontogenetic variation in Recent fishes (Coombs et al 1988, Arratia & Huaqufn 1995 .…”

The late Late Jurassic fishes collected by the Tendaguru expeditions (1909)(1910)(1911)(1912)(1913) are represented only by a shark tooth and various specimens of the neopterygian Lepidotes . The Lepidotes is a new species characterized by a combination of features such as the presence of scattered tubercles in cranial bones of adults, smooth ganoid scales, two suborbital bones, one row of infraorbital bones, non-tritoral teeth, hyomandibula with an anteriorly expanded membranous outgrowth, two extrascapular bones, two postcleithra, and the absence of fringing fulcra on all fins.
