“…This LC was thought to enhance the sound detection by transmitting the sound pressure stimuli to the lateral line via the swim bladder horns, and converting the sound pressure to fluid flow through a laterophysic tympanum (Webb, 1998;Webb and Smith, 2000;Smith et al, 2003;Webb et al, 2006). Surprisingly, Webb et al (2012) did not observe a relationship between fish size and hearing abilities in Chaetodon ocellatus but they measured AEP audiograms with individuals ranged in size from 21 to 31 mm (vs 36-85 mm in the present study). The medial opening in the supracleithral lateral line canal in C. ocellatus is present in 14-17 mm individuals.…”

“…The medial opening in the supracleithral lateral line canal in C. ocellatus is present in 14-17 mm individuals. However, the swim bladder horns are formed when specimens reach the size of 25 to 29 mm, which roughly corresponded to their sample size (Webb et al, 2012). Although the distance between the swim bladder horns and both the medial opening in the supracleithral lateral line canal and the inner ear did not change appreciably during growth in C. ocellatus (Webb et al, 2012), it might be different in the case of C. citrinellus due to a different development of the LC system.…”

“…5). Previous studies have already measured behavioral audiograms in holocentrids (Tavolga and Wodinsky, 1963;Coombs and Popper, 1979), as well as AEP audiograms in a few pomacentrids (Egner and Mann, 2005;Wright et al, 2005;Wysocki et al, 2009) and chaetodontids (Webb et al, 2012;Tricas and Boyle, 2015). However, direct comparison of these studies with our AEP traces can be irrelevant because audiograms produce very different results depending on the methodology used (i.e.…”

Just after the reef colonization, fish species could use the acoustic cue to settle on different suitable habitats. In the present study, we used the auditory evoked potential (AEP) technique to measure and compare the detection abilities in five coral reef fish species, with some of these species that are found in the same habitat. We also examined the effect of fish size on sensitivity at the species level. All studied species except one showed size-related changes in sensitivity characterized by either a decrease (i.e. higher AEP thresholds) or an increase (i.e. lower AEP thresholds) in detection abilities with increasing size. The interspecific comparison of audiograms revealed that some species are more sensitive than others in terms of sound pressure level and frequency detection. Overall, this study indicates that the AEP threshold and the frequency bandwidth at early life stages may vary between and within fish species. The detection abilities are different in fish species that are not phylogenetically related, which might suggest that the establishment of their capabilities is not necessarily related to the reef conquest.

“…Pressure components of sound waves are thought to be detected by vibration of internal gas-filled structures such as the fish's swim bladder, auditory bullae or various branchial bubbles (Popper and Fay, 1999). The gas-filled structures vibrate in response to sound waves, sending these vibrations to hair cells as displacement stimuli, although a few species have also been shown to have a connection between a gas bubble and the lateral line system (Webb and Smith, 2000;Webb et al, 2012) and thus may gain displacement information via this channel as well.…”

SUMMARYIn the underwater environment, sound propagates both as a pressure wave and as particle displacement, with particle displacement dominating close to the source (the nearfield). At the receptor level, both the fish ear and the neuromast hair cells act as displacement detectors and both are potentially stimulated by the particle motion component of sound sources, especially in the nearfield. A now common way to test ʻhearingʼ in fish involves auditory evoked potentials (AEPs), with recordings made from electrodes implanted near the auditory brainstem. These AEP recordings are typically conducted in enclosed acoustic environments with the fish well within the nearfield, especially for lower frequencies. We tested the contribution of neuromast hair cells to AEP by first testing intact goldfish (Carassius auratus), then ablating their neuromasts with streptomycin sulphatedisabling superficial and canal neuromasts -and retesting the same goldfish. We performed a similar experiment where only the superficial neuromasts were physically ablated. At 100 and 200Hz, there was a 10-15dB increase in threshold after streptomycin treatment but no significant difference at higher frequencies. There was no difference in threshold in control fish or in fish that only had superficial neuromasts removed, indicating that the differential responses were driven by canal neuromasts. Taken together, these results indicate that AEP results at lower frequencies should be interpreted as multimodal responses, rather than as ʻhearingʼ. The results also suggest that in natural situations both the ear and lateral line likely play an integrative role in detecting and localising many types of ʻacousticʼ stimuli.

Fast drum strokes: Novel and convergent features of sonic muscle ultrastructure, innervation, and motor neuron organization in the pyramid butterflyfish (hemitaurichthys polylepis)

Sound production that is mediated by intrinsic or extrinsic swim bladder musculature has evolved multiple times in teleost fishes. Sonic muscles must contract rapidly and synchronously to compress the gas-filled bladder with sufficient velocity to produce sound. Muscle modifications that may promote rapid contraction include small fiber diameter, elaborate sarcoplasmic reticulum (SR), triads at the A-I boundary, and cores of sarcoplasm. The diversity of innervation patterns indicate that sonic muscles have independently evolved from different trunk muscle precursors. The analysis of sonic motor pathways in distantly related fishes is required to determine the relationships between sonic muscle evolution and function in acoustic signaling. We examined the ultrastructure of sonic and adjacent hypaxial muscle fibers and the distribution of sonic motor neurons in the coral reef Pyramid Butterflyfish (Chaetodontidae: Hemitaurichthys polylepis) that produces sound by contraction of extrinsic sonic muscles near the anterior swim bladder. Relative to adjacent hypaxial fibers, sonic muscle fibers were sparsely arranged among the endomysium, smaller in cross-section, had longer sarcomeres, a more elaborate SR, wider t-tubules, and more radially arranged myofibrils. Both sonic and non-sonic muscle fibers possessed triads at the Z-line, lacked sarcoplasmic cores, and had mitochondria among the myofibrils and concentrated within the peripheral sarcoplasm. Sonic muscles of this derived eutelost possess features convergent with other distant vocal taxa (other euteleosts and non-euteleosts): small fiber diameter, a well-developed SR, and radial myofibrils. In contrast with some sonic fishes, however, Pyramid Butterflyfish sonic muscles lack sarcoplasmic cores and A-I triads. Retrograde nerve label experiments show that sonic muscle is innervated by central and ventrolateral motor neurons associated with spinal nerves 1-3. This restricted distribution of sonic motor neurons in the spinal cord differs from many euteleosts and likely reflects the embryological origin of sonic muscles from hypaxial trunk precursors rather than occipital somites.
