“…The taxonomic, anatomical, behavioral and physiological variation among fishes is immense and includes both the ear and the peripheral structures associated with the ear [e.g., Retzius, 1881], leading to the suggestion that various species may detect and process sound in different ways, depending upon their peripheral auditory structures, the acoustic characteristics of their usual environment, or even upon their taxonomic positions Popper, 1983;Schellart and Popper, 1992]. This diversity has lead several investigators to caution against referring to 'the' fish with regard to hearing or the auditory system [Piatt and Popper, 1981;Schellart and Popper, 1992], since the taxa are too broad and the variations too great to permit such generalizations without our having a more comprehensive understanding of audition | among fishes. The bony fishes are divided into four subclasses, as illustrated in figure 1 [see Lauder andLiem, 1983, andNelson, 1984, for general taxonomy].…”

The literature on fish hearing has increased significantly since our last critical review in 1973. The purpose of the current paper is to review the more recent literature and to identify those questions that need to be asked to develop a fuller understanding of the auditory capabilities and processing mechanisms of fishes. We conclude that while our understanding of fish hearing has increased substantially in the past years, there are still major gaps in what we know. In particular, the comparative functional literature is extremely limited, and we do not yet know whether different species, and particularly hearing specialists as compared to hearing nonspecialists, have fundamentally different auditory capabilities and mechanisms.

“…The three-otolith pairs in teleost have a large morphological variability (Lombarte and Cruz 2007). This variability is especially true for the saccular otolith (sagitta) associated with the inner ear organ, sacculus, in non-ostariophsean fi shes (Platt andPopper 1981, Lombarte andCruz 2007). The morphological differences affect both the size and shape of the otoliths (Paxton 2000).…”

Background. The annular seabream, Diplodus annularis (Linnaeus, 1758), is the most common sparid fi sh in the Mediterranean Sea. This species is widespread in Tunisia. Despite their economic importance, due to their excellent white and delicate fl esh (demersal fi sh) and their signifi cant size, few studies have hitherto focused on stock discrimination and on the fi sheries management. The goal of this research was to evaluate the stock structure of D. annularis for two Tunisian insular populations based on the otolith shape, using different statistical approaches. Materials and methods. The specimens of Diplodus annularis were collected during fi ve months ranging from May through September 2014 at two sites: Djerba and Kerkennah. In total, 120 fi sh were collected from the two sites: 60 specimens of each population (30 males and 30 females) and were included in different statistical analyses. The Fourier coeffi cients were determined to evaluate the degree of similarity in the otoliths and detect the reciprocal variability. Results. By comparing the two studied populations, we revealed statistical signifi cant differences, an asymmetry (left-right), of otoliths (P < 0.05). In the same population, symmetry (left-right) was detected for the males, females of Kerkennah, and females of Djerba. However, an asymmetry was detected only for the males of Djerba. Also, sexual dimorphism was observed only for the Djerba population. Conclusion. The comparison of the otolith morphology of the two populations showed a clear difference in shape and a left-right asymmetry of otoliths. This asymmetry indicates that the two populations belong to different stock of fi sh. The stocks characterization is considered as an important tool for fi sheries management. Further studies are necessary to determine the origin of the otolith shape differences and whether they are related only to environmental conditions or a genetic basis may also be responsible.

“…The otoliths are acellular concretions of calcium carbonate and other inorganic salts developing over a protein matrix (Carlström 1963, Blacker 1969, Degens et al 1969 and in close association with the sensorial macula (Platt and Popper 1981, Lychakov and Rebane 2000, Schulz-Mirbach et al 2011. The otoliths, especially the sagittae, play an important role in inner ear functions (Platt and Popper 1981, Popper and Fay 1993, Popper and Lu 2000. Previous studies have indicated that the size of the sagittae is an adaptive factor associated with sensitivity to sound (Myrberg 1980, Montgomery and Pankhurst 1997, Paxton 2000, Cruz and Lombarte 2004.…”

“…Morphologically, the inner ear of teleostean fishes is essentially formed by three semicircular canals and otolithic organs (sacculus, utriculus and lagena), within which are located the otoliths (sagitta, lapillus and asteriscus, respectively) (Assis 2003, 2005, Cermeño et al 2006.

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...
