“…The greatest sensitivity of yellowfin occurs between 200 and 800 Hz, where the mean thresholds ranged from 89 to 100 dB re 1 µPa. This evidence concurs with that of the vast majority of fish studied to date which appear to have, apart from a few species with specialist hearing, a relatively narrow audible frequency range (Popper 2000). It thus appears reasonable that the experimental bluefin tuna in our study responded mainly to noises falling within the range observed by Iversen (1967).…”

The effect of boat noise on the behaviour of bluefin tuna Thunnus thynnus was investigated\ud in the Egadi Islands, Sicily, during spring 2005 using a fixed tuna trap set near shipping routes.\ud Tuna behaviour was observed when exposed to both natural ambient sound and sound generated by\ud hydrofoil passenger ferries, small boats and large car ferries. Acoustical and behavioural analyses\ud were conducted with and without extraneous sound to define a list of behavioural categories. Each\ud vessel produced different engine sounds with regard to their composition and bandwidth, and all\ud were distinctly different from ambient sound levels. In the absence of boat noise, tuna assumed a concentrated\ud coordinated school structure with unidirectional swimming and without a precise shape.\ud When a car ferry approached, tuna changed swimming direction and increased their vertical movement\ud toward surface or bottom; the school exhibited an unconcentrated structure and uncoordinated\ud swimming behaviour. Hydrofoils appeared to elicit a similar response, but for shorter periods. Agonistic\ud behaviour was more evident when exposed to sounds from outboard motors of small boats. This\ud study showed that local noise pollution generated by boats produced behavioural deviations in tuna\ud schools. Schooling enhances tuna homing accuracy during their spawning migration, and an alteration\ud in schooling behaviour can affect the accuracy of their migration to spawning and feeding\ud grounds

“…An invagination of the otic placode to form an otic vesicle is a character of the crown craniate group (Maisey, 1986;Janvier, 1996). The inner ear probably did not evolve from the lateral line, or vice-versa, but both probably arose independently (and at different times) from a loosely-arranged system of superficial neuromast organs or placodes (see also Popper et al, 1992;Popper, 2000).…”

The structure and function of the craniate inner ear is reviewed, with 33 apomorphic characters of the membranous labyrinth and associated structures identified in craniates, gnathostomes, and elasmobranchs. Elasmobranchs are capable of low-frequency semi-directional phonoreception, even in the absence of any pressure-to-displacement transducer such as ear ossicles. The endolymphatic (parietal) fossa, semicircular canals, and crista (macula) neglecta are all adapted toward phonoreception. Some (but not all) of the morphological features associated with phonoreception can be inferred from the elasmobranch skeletal labyrinth. Endocranial spaces such as the skeletal labyrinth also provide suites of morphological characters that may be incorporated into phylogenetic analyses, irrespective of how closely these spaces reflect underlying soft anatomy. The skeletal labyrinths of Squalus and Notorynchus are compared using silicone endocasts and high-resolution CT-scanning. The latter procedure offers several advantages over other techniques; it is more informative, nondestructive, preserves relationships of surrounding structures, and it can be applied both to modern and fossil material.

“…Type II hair cells contact small bouton endings of primary afferent neurites and the outer faces of neighboring calyces (Spoendlin, 1965;Engström, 1970;Ross et al, 1985). Anamniotes (fish and amphibians) such as the toadfish have traditionally been described as having only type II-like elements (Wersä ll, 1960;Flock, 1964;Gleisner et al, 1973), although there is increasing evidence for the existence of a multiplicity of morphologically defined hair cell types in these species (Popper, 2000). The present study was conducted to visualize the three-dimensional spatial distribution of GABA and glutamate immunolabeling in whole mounts of the vestibular labyrinth of the oyster toadfish, to examine the regional distribution of hair cell transmitter phenotype and the relationship between GABAergic and glutamatergic sensory cells.…”

Although gamma-aminobutyric acid (GABA) and glutamate are known to be present in the vestibular sensory epithelia of a variety of species, the functional relationship between these two transmitters is not clear. The present study addresses the three-dimensional spatial distribution of GABA and glutamate immunoreactivity in the vestibular labyrinth of the oyster toadfish by using whole end organs labeled by immunofluorescence with monoclonal anti-GABA and/or antiglutamate antibodies and visualized as whole mounts by multiphoton confocal microscopy. We find glutamate-immunoreactive hair cells present throughout the sensory epithelium. In contrast, prominent GABA immunoreactivity is restricted to a small population of hair cells located in the central region of the crista. Double immunofluorescence reveals two distinct staining patterns in GABA-labeled hair cells. Most ( approximately 80%) GABA-labeled cells show trace levels of glutamate, appropriate for the metabolic/synthetic role of cytoplasmic glutamate. The remainder of the GABA-stained cells contain substantial levels of both GABA and glutamate, suggesting transmitter colocalization. In the toadfish utricle, glutamatergic hair cells are present throughout the macula. GABA-immunoreactive hair cells follow the arc of the striola, and most GABA-labeled receptor cells coexpress glutamate. The localization of GABA was explored in other species as well. In the pigeon, GABAergic hair cells are present throughout the crista ampullaris. Our findings demonstrate that multiple, neurochemically distinct types of hair cells are present in vestibular sensory epithelia. These observations, together with the excitatory activity generally associated with 8th nerve afferent fibers, strongly suggest that GABA serves an important, specific, and complex role in determining primary afferent response dynamics.
