The relative roles of the fish lateral line and inner ear for the perception of hydrodynamic stimuli are poorly investigated.
Here, we studied responsiveness to a 100 Hz vibrating sphere (dipole stimulus) of goldfish and oscars, two species that differ
in peripheral lateral line morphology, inner ear morphology, mechanical linkage between inner ear and swim bladder, and inner
ear sensitivity. We measured unconditioned dipole-evoked changes in breathing activity in still water and in the presence
of a 5-cm s−1 background flow. In still water, individuals from both species responded to sound pressure levels (SPLs) between 92 and 109 dB
SPL re 1 μPaRMS. Responsiveness was not affected by background flow or by temporary inactivation of the lateral line. The data suggest that
fish with different lateral line and inner ear morphologies have similar sensitivities to vibrating sphere stimuli and can
detect and respond to dipole sources equally well in still water and in moderate background flows. Moreover, behavioral responses
were not dependent on a functional lateral line, suggesting that in this type of experiment, the inner ear is the dominant
sense organ for the perception of hydrodynamic stimuli. 相似文献
