From the morphospace to the soundscape: Exploring the diversity and functional morphology of the fish inner ear, with a focus on elasmobranchs

The Journal of the Acoustical Society of America, Journal Year: 2023, Volume and Issue: 154(3), P. 1526 - 1538

Fishes, including elasmobranchs (sharks, rays, and skates), present an astonishing diversity in inner ear morphologies; however, the functional significance of these variations how they confer auditory capacity is yet to be resolved. The relationship between structure hearing performance unclear, partly because most morphological biomechanical mechanisms that underlie functions are complex poorly known. Here, we advanced opportunities document discontinuities macroevolutionary trends a biological form, like ear, test hypotheses regarding what factors may driving diversity. Three-dimensional (3D) bioimaging, geometric morphometrics, finite element analysis methods can combined interrogate structure-to-function links elasmobranch fish ears. In addition, open-source 3D morphology datasets, advances phylogenetic comparative methods, for highly multidimensional shape data have leveraged opportunities. Questions explored with this toolkit identified, different justified, remaining challenges highlighted as avenues future work.

A journey through the field of fish hearing

The Journal of the Acoustical Society of America, Journal Year: 2023, Volume and Issue: 153(5), P. 2677 - 2689

Published: May 1, 2023

My interest in fish bioacoustics was ignited more than 50 years ago and resulted a zigzag time travel between various interesting problems that were unsettled at the time. The present paper gives brief overview of main topics I have worked on field hearing, i.e., auditory function swim bladder, directional lateral line system, infrasound sensitivity. Rather being comprehensive review these issues, is autobiographical limited. aim to show young scientists experimental science can be exciting, diverse, rewarding—and open doors rich collegial network, collaboration, friendships.

Comparison of auditory evoked potential thresholds in three shark species

Journal of Experimental Biology, Journal Year: 2023, Volume and Issue: 226(18)

Published: July 13, 2023

Auditory sensitivity measurements have been published for only 12 of the more than 1150 extant species elasmobranchs (sharks, skates and rays). Thus, there is a need to further understand sound perception in from different ecological niches. In this study, auditory evoked potential (AEP) technique was used compare hearing abilities bottom-dwelling New Zealand carpet shark (Cephaloscyllium isabellum) two benthopelagic houndsharks (Triakidae), rig (Mustelus lenticulatus) school (Galeorhinus galeus). AEPs were measured response tone bursts (frequencies: 80, 100, 150, 200, 300, 450, 600, 800 1200 Hz) an underwater speaker positioned 55 cm front experimental tank. AEP detection thresholds derived visually statistically, with statistical measures slightly sensitive (∼4 dB) visual methodology. Hearing differed between species, mainly respect bandwidth rather sensitivity. least developed benthic C. isabellum [upper limit: 300 Hz, highest sensitivity: 100 Hz (82.3±1.5 dB re. 1 µm s-2)] had wider range sharks Hz; (79.2±1.6 s-2) G. galeus 150 (74.8±1.8 M. lenticulatus]. The data are consistent those known 'hearing non-specialist' teleost fishes that detect particle motion, not pressure. Furthermore, our results provide evidence exploit higher frequencies (max. some Hz). Further behavioural morphological studies needed identify what factors drive differences upper frequency limits elasmobranchs.

Comparison of acoustic particle acceleration detection capabilities in three shark species

Journal of Experimental Biology, Journal Year: 2023, Volume and Issue: 226(18)

Published: Sept. 4, 2023

Behavioural studies have shown that sharks are capable of directional orientation to sound. However, only one previous experiment addresses the physiological mechanisms hearing in sharks. Here, we used a shaker table combination with auditory evoked potential (AEP) technique understand broadscale capabilities New Zealand carpet shark (Cephaloscyllium isabellum), rig (Mustelus lenticulatus) and school (Galeorhinus galeus). The aim this was test if more sensitive vertical (z-axis) or head-to-tail (x-axis) accelerations, whether there any differences between species. Our results support findings, suggesting ears can receive sounds from all directions. Acceleration detection bandwidth narrowest for (40-200 Hz), broader (40-800 Hz). Greatest sensitivity bands were 40-80 Hz shark, 100-200 80-100 shark. indicate may be abilities among bottom-dwelling equally particle accelerations. In contrast, both benthopelagic appeared accelerations at frequencies up 200 Hz. This is first study provide evidence differ their sound localisation abilities. Further comparative behavioural species different lifestyles, habitats feeding strategies needed further explore drivers increased elasmobranchs.

Sound and sturgeon: Bioacoustics and anthropogenic sound

The Journal of the Acoustical Society of America, Journal Year: 2023, Volume and Issue: 154(4), P. 2021 - 2035

Published: Oct. 1, 2023

Sturgeons are basal bony fishes, most species of which considered threatened and/or endangered. Like all sturgeons use hearing to learn about their environment and perhaps communicate with conspecifics, as in mating. Thus, anything that impacts the ability sturgeon hear biologically important sounds could impact fitness survival individuals populations. There is growing concern produced by human activities (anthropogenic sound), such from shipping, commercial barge navigation on rivers, offshore windfarms, oil gas exploration, aquatic organisms. it critical understand how hear, what they sound. Such data needed set regulatory criteria for anthropogenic sound protect these animals. However, very little known behavioral responses To help issues related sound, this review first examines bioacoustics. It then considers potential effects and, finally identifies areas research substantially improve knowledge bioacoustics Filling gaps will regulators establish appropriate protection sturgeon.

Hearing diversity in 34 000 fish species: A personal perspective

I have been studying fish hearing since 1966. Over that time, my interests evolved from basic mechanisms of to “translational bioacoustics” where help apply science the protection fishes potential harm arising anthropogenic sources. Yet, am still most interested in questions. Thus, this paper focuses on questions and shares personal view some interesting important think need be asked about by future investigators. Accordingly, not focusing what has learned, but, rather, focus raised we learned. Moreover, is comparative—there are more than 34 000 extant species—and know little any one species. Indeed, our knowledge comes 100 species! Therefore, considering immense importance fishes, it contention a great deal sense gives rapid highly directional information, often at distance, world around them.

Functional plasticity of the swim bladder as an acoustic organ for communication in a vocal fish

Published: Dec. 13, 2023

Teleost fishes have evolved a number of sound-producing mechanisms, including vibrations the swim bladder. In addition to sound production, bladder also aids in reception. While production and reception by has been described separately fishes, extent which it operates for both single species is unknown. Here, using morphological, electrophysiological modelling approaches, we show that male plainfin midshipman fish (
